Fluoride Debate - An exercise in truth decay by Dr Don Mac Auley.

PictureMicheal Martin has questions to answer?

We drink it every day without a moment´s thought. Soon we´ll be paying for it. But what price have we already paid for our drinking water over the last fifty years? 

There is a growing belief that the chemical fluoride, added to our drinking water in Ireland since the 1960s to reduce tooth decay, has caused – and continues to cause – damage to both the health and the teeth of Irish citizens.
A cumulative poison, fluoride has been linked to hip fractures, reduced IQ in children, bone cancer and thyroid problems. The majority of European countries have tried fluoridation and stopped it. Some have gone as far as banning it.

As readers of Hot Press will know, Ireland is the only European country to mandate this mass-medication from central government and, as a result, we have the highest levels of fluoride-induced tooth damage in Europe. Called dental fluorosis, this damage manifests itself as white lines or pitting on the surface of teeth.

Dental fluorosis is the first sign of fluoride poisoning.

So, why is there no uproar? Why are people not marching the streets, demanding an end to this outrage?

Well, we did protest. Back in 2000, new international studies linking water fluoridation to serious health damage led to a nationwide campaign, with – as reported in the Irish Independent in June 2001 – 32 town and county councils voting to take the chemical out of Irish tap water.




Back then, dentists too, were complaining about the epidemic levels of dental fluorosis in children's teeth. Even the Minister of Health at the time, Micheál Martin's own Cork Corporation voted for an end to fluoridation in October 2001. This decision, however, was not theirs to make. Under the law, fluoride is centrally mandated. The only way it can be removed from the water supply is by a change in the law, meaning that the decision is in entirely in the hands of the Department of Health and the relevant Minister, currently a Junior Minister, Alex White.
In response to the wave of public concern, in May 2000, Martin set up the Forum on Fluoridation. It was heralded as an opportunity to “independently review the fluoridation of piped water supplies.” But what happened over the next two years is a chilling tale of cover-up, amounting to scientific fraud, when (a) a clique of researchers went to great lengths to defend existing public health policy instead of public health; and (b) the Food Safety Authority of Ireland changed minutes of meetings, buried a damning report and ultimately appeared to mislead the Dáil.

At the heart of it all are valuable research grants, where the same researchers received millions in tax-payers money as they continued to lobby to keep fluoride in our drinking water.
It is safe to suggest now that the real reason for the forum may have been to take the heat out of the situation and to provide a platform to undermine the anti-fluoride campaign. As is the case throughout this extraordinary story, the language used by Micheál Martin, in the press release issued by the Department of Health, gives the game away. "The Forum will perform a very valuable function in looking into all aspects of the fluoridation debate, answering concerns which the public may have…" he said.

The assumption from the outset therefore was that the concerns would be "answered". Lest there be any doubt about the Department and the Minister's position, at the start of what was supposed to be an independent review, he nailed his colours firmly to the fluoride mast.  "Fluoridation," the Minister continued, "has made a major contribution to the oral health of the Irish population over the last thirty seven years. Oral health gains have been made by children, adults and especially the socially deprived with a reduction in dental decay rates of 70%."  


Clearly, the forum was never going to be the detailed health study required by law. That became even clearer when the membership of the Forum was announced: it was top-heavy with pro-fluoride “experts”, as analysed on the Fluoride Free website at the time. Many were government dentists or dental researchers who had already travelled the world promoting water fluoridation in other countries. Among these was Professor Denis O Mullane, the head of the Oral Health Services Research Centre at UCC. O Mullane describes himself as an “independent research worker” who has been studying, as he put it to the Oireachtas' Joint Committee on Health & Children in 2003,  “the effectiveness of water fluoridation for 32 years”. 

Picture
Denis O Mullane - promoting fluoride in Ireland and abroad.

Every study carried out by O Mullane has supported his opinion that fluoridation is safe and more importantly cost-effective. The vast majority of Irish studies regarding fluoride have passed through O Mullane and his team in Cork. His track record is flawless: not one study from Europe, in countries without fluoridation which havebetter teeth than the Irish, that can't be explained away.What no one had figured, in their rush to rubber stamp the fluoridation of the Irish people, was that there were a few independent scientists on the Forum, interested in a genuine review. Dr. Wayne Anderson represented the Food Safety Authority of Ireland (FSAI), an organisation that holds a statutory responsibility for the safety of our food. After all, once you dump fluoride into the water you also contaminate any food that requires water in its preparation.

One in particular that uses fluoridated water drew interest from the FSAI: baby formula feed. Since 1994, a growing number of international studies had shown babies living in areas with water fluoridation were being overdosed with fluoride. These studies showed that, due to their large consumption of water in relation to their small size, infants were particularly sensitive to the chemical, showing worrying levels of fluoride poisoning – dental fluorosis.
Aware of these concerns, the FSAI commissioned Anderson and two other toxicologists to carry out a fluoride assessment on Irish infants under four months of age to see if there was a similar risk of damage here. Incredible as it seems, this was the first toxicological investigation of fluoridated water in the history of the Irish state. But, according to the records we have seen, Anderson didn't inform his dentist colleagues on the Forum of their work: there is no reference to the study in the minutes of the many meetings. Why? After all, it was groundbreaking research.

It was also the first fluoride study that hadn´t been carried out by dentists, nor had it passed through O Mullane in Cork. Could the FSAI have chosen not to inform the Forum, because they felt other researchers on the Forum would try and influence the independence and findings of their study? Either way, this is, indeed, exactly what did happen later, when the FSAI finally presented their 25-page report to the Forum on Fluoridation.

The toxicologists' conclusions in that report were genuinely shocking. Having accessed it under a Freedom of Information request, we can confirm that it states that bottle-fed infants were receiving up to seven times the safe dose of fluoride.

“Fluoride is a potentially hazardous substance that exhibits a wide range of health effects in man," it warned. "These range from mild effects such as mild dental fluorosis at low doses to severe acute toxic effects at high doses.” The toxicologists' concerns about the fluoride levels swallowed by babies went far beyond concern for their teeth. “It is also envisaged that doses of this magnitude could result in significant levels of skeletal fluorosis,” the report stated.

In other words, the water in Ireland, fluoridated by the Irish state,  could be causing bone damage in babies, when used to make up formula milk. At the Scientific Committee meeting of the FSAI on 3 October 2001, the minutes of which we have seen, the full board supported the position that, because of this new evidence, “infant formula should not be reconstituted with fluoridated tap water.” The FSAI scientific committee was clear: Irish tap water was not safe to make up babies' bottles.


However, there was no rush to inform the public. On the contrary, in what, in my view, amounts to scientific fraud, the FSAI subsequently buried the report and changed the minutes of meetings. What's more, their member on the Forum would later fail to inform the Dáil of everything he knew. The timeline of what happened presents a damning indictment of those charged with responsibility for public health in Ireland.


A week before the FSAI's Scientific Committee reached their original conclusions, the Forum on Fluoridation held its last meeting for which there are minutes. Everything was rosy and members were reminded that there were only two meetings left, on  October 18 and 25 respectively, before the Final Report would be presented to the Minister of Health at the end of October.

On 11 October, the FSAI findings were circulated to members. The mood changed dramatically: the Forum went into information shutdown. No minutes would be taken for the final two Forum meetings. This was a remarkable decision considering the Forum had been funded from the public purse and would decide on a policy that affected every Irish citizen.

What exactly the Forum discussed during these meetings we'll never know. But thanks to the Freedom of Information Act, we do know now what happened to the FSAI study and why it was never made public.
The reason we know this is that there was a third, top-secret meeting – a meeting that never took place, according to the website of the Forum on Water Fluoridation in Ireland. At this meeting, held on 23 October, the minutes from which we have accessed under the Freedom of Information Act, the same researchers who had spent their careers promoting fluorides were in the remarkable position of having to discuss an end to water fluoridation in Ireland.

The meeting had been organised by the Forum Chairman, Professor Patrick Fottrell, “to consider the implications” of the FSAI study on water fluoridation. Note the wording here: there was no question about the results. This was a meeting to plan the next move, given the FSAI's damning conclusions.

Among those in attendance was O Mullane, who had informed the Dáil the year before, “For over 30 years, I have conducted epidemiological studies in Ireland and overseas. A major focus of my work has been measuring the effectiveness of fluoride.”

The question might have been asked of O Mullane: if he had been so busy studying fluoride in his research centre in UCC, for more than three decades, why did he not know that bottle-fed infants were receiving unsafe amounts of fluoride from Irish tap water? After all, this was not new information – published studies hadhighlighted similar concerns dated back to 1994. Or – as elsewhere in this saga, is the clue to O Mullane's apparent lack of interest in fluoride damage betrayed by the language in his Dáil statement: “I have been measuring the effectiveness of water fluoridation for 32 years”?

If he had only been reviewing the positive effects of fluoridation, had he been ignoring the damage inflicted on those most vulnerable in society, as the FSAI states: Irish infants under four months of age, who have no teeth. Maybe O Mullane saw the toxicological report, agreed by nine independent Irish scientists, as the writing on the wall for a public health policy he had spent 32 years defending. That this is what was at stake is clarified in the minutes of the meeting, with the heading: “Stop Fluoridation or continue fluoridation.”
Another revelation from the meeting clarifies that the number of infants being damaged by fluoride was significant. “In 1998, there were 53,551 births," the minutes record, "therefore at any one time there will be a large cohort consuming infant formula… As the rate of breastfeeding in this country is extremely low, the number of infants receiving infant formula is considerable.” Reading the minutes you get the feeling there was a tug of war in progress: on the one side the pro-fluoride side questioning the study, while the others preach the importance of the precautionary principle.

We now know which side prevailed in the debate – but at what cost to the credibility of the FSAI? And more importantly, to the health of Irish babies?

The very next day the foregone was concluded. The possibility of causing bone damage in infants under four months old hadn't even given the Forum a bad night's sleep. On 24 October, the chairman of the Forum, Dr.Patrick Fottrell sent a confidential note stating that “The Forum recommends the continuation of fluoridation of public piped water supplies.”

The statement prepared by the Chairman and the Forum members, and handed to Christy Mannion for the Minister´s attention, amounts to scientific and medical negligence.
Not only had they ignored the scientific evidence, the Forum subsequently went on to pressurise the FSAI into withdrawing their study. Three days after the crucial, secret meeting Wayne Anderson, the FSAI´s representative on the Forum, wrote to the FSAI's own Scientific Committee explaining that they'd missed the deadline. “The risk assessment had to be withdrawn…" he added… "the document cannot now be re-submitted and there will be no mention of the risk assessment in the final report of the Forum to the Minister.”

Although Anderson apparently had buckled, at first the FSAI were not for turning. At the following meeting of the Subcommittee on Additives, Chemical Contaminants and Residues, on 30 Oct 2001, the FSAI again reiterated its position and “decided to adopt the precautionary principle in this matter”, confirming that infant formula not be made up with fluoridated tap water.
Later, according to reports in The Examiner at the time, the minutes of both these FSAI meetings would be changed and the FSAI study buried. The Forum delayed its report for another year while the Forum and FSAI debated the fluoride poisoning of Irish infants. And it all happened behind closed doors.

On 10 Sept 2002, the Forum finally published its recommendation  that the levels of fluoride in our tap water should be reduced. This also is extraordinary: in all of the public documents presented by the Forum there is not one reference to turning down the fluoride taps. It is only ever mentioned in the minutes of the top-secret meeting, during which the debate raged about what to do with formula fed infants. “It was found," the minutes note, "that while tighter control (of fluoridation) coupled with a lower target value of 0.6 to 0.8 mg would decrease the degree of overexposure it would not eliminate it completely.” 

In other words, fluoridation will still cause damage to bottle-fed infants, just not as much.

Picture
Dr Wayne Anderson FSAI misled Dail?

The subsequent collusion between the FSAI and the Forum to keep this information from the public was staggering. In 2003, before the Oireachtas Health Committee, Dr Wayne Anderson completed the obfuscation. John Gormley (Green Party) asked Anderson: if the original report had not been changed would it have meant an end to water fluoridation in Ireland? His answer was this: “I do not know the full details of how that would have affected it, I would be speculating.”

It seems impossible to square that statement with the minutes, which confirm that Dr. Anderson was present at the top-secret meeting when Forum members discussed and debated an end to fluoridation on the back of a study
he himself had presented two weeks earlier.

In 2007, the Minister for Health in the Fianna Fáil/PD coalition government, Mary Harney, finally acted on the Forum's primary recommendation to reduce the level of fluoride in our drinking water. This was all of six years after the FSAI study reported that formula fed infants were receiving SEVEN times the safe dose. Interestingly, three years earlier, in 2004, Micheál Martin actioned a lesser recommendation, when he set up the Irish expert body on fluorides and health; clearly, the “expert” body was more important than the health of Irish infants.

The familiar figures of Anderson, O Mullane and other pro-fluoride members of the Forum were predictably invited to participate in yet another quango paid for by the Irish tax-payer. This was not the only benefit for O Mullane: at the height of the storm over the infant formula in 2002, he received an award from fellow Corkman Martin of €500,000-€1,000,000 to conduct research into "the benefits and risks of water fluoridation."
Wading through the relevant documentation, it becomes ever clearer that what happened between the Forum and the Food Safety Authority regarding water fluoridation in Ireland is scandalous.

The way in which a report from the FSAI was subverted by the Forum on Fluoride surely has implications for the ethics and independence of scientific study in this country. But, more importantly it shows us fluoride health researchers prefer to protect policy than the most vulnerable in our society. This was the case in the 1960s when a group of dentists and the Fianna Fail government thought they knew better; and they still think they know better, even though international research increasingly links fluoride to serious health and teeth damage.

Mary Raftery, the journalist who exposed child abuse in church-run schools once posed the question – Do they think we're eejits? Regarding fluoride in our drinking water, the answer is yes. And next year they'll expect us eejits to pay for their poison – as if we haven't already paid enough.

Fluoride Debate: Another Whitewash on the Way?

Published in Hotpress 18th Dec 2013
http://www.hotpress.com/politics/frontlines/Fluoride-Debate-Another-Whitewash-on-the-Way/10748636.html

Though organisations such as Irish Dentists Opposing Fluoridation continue to highlight 
major concerns about the Irish water system, there are fears that a new government review 
will fail to tackle the real issues.

Don MacAuley was a key fluoride whistleblower back in 2000. He founded the 100-strong group, Irish Dentists Opposing Fluoridation, helping to generate a significant breakthrough in public and media awareness of the health risks associated with fluoride in the early years of the Noughties.

That campaign was effectively smothered by the ‘Forum on Fluoridation’, set up by then Minister for Health Micheál Martin in 2002. Over the past year, however, fluoride awareness has taken another leap forward, urged on by the combined efforts of The Girl Against Fluoride, Aisling FitzGibbon; the research of scientist, Declan Waugh; the ongoing Hot Press investigation; Sinn Féin TD Brian Stanley, Labour TD Emmet Stagg and other individual politicians; and the work of many grassroots campaigners.

Dr MacAuley has now returned to the fray. Originally from Co. Tyrone, he studied in the UK to be a dentist and, having qualified, worked abroad. He first became aware that there was an issue about fluoride when he returned to Ireland in 1998.

Initially he was sceptical that there were health risks, but he quickly uncovered what he believed were convincing studies linking fluoride to serious adverse health effects.

Unable to get straight answers from the Department of Health and the Irish Dental Association to his queries about fluoride, MacAuley began using the Freedom of Information Act (FOI) to gather information. He says that he received several warnings from senior dentists in the Health Board to drop his FOI investigation and that he ultimately lost his job. Finding it impossible to get work, MacAuley set up his own practice in Navan, Co Meath, which he still runs.

It was only by chance that, in January 2002, MacAuley happened upon a mention on the Food Safety Authority of Ireland (FSAI) website of a fluoride assessment being conducted by the FSAI. A week later when he looked, all mention of the assessment had been removed. It was only by pushing to the max through the FOI (with the FSAI resisting all the way) that MacAuley was able to find out more about the FSAI report. That information is revealed in full for the first time in the accompanying article.

As we have previously suggested in Hot Press, the level of resistance in the Department of Health to anti-fluoridation views is almost impossible to understand. Thomas Sheridan, an internationally known Irish expert on socialised psychopaths, and author of several books on the subject, believes that it is very sinister.

“Fluoride could be the most negative and damaging issue since the Catholic abuse situation,” he told Hot Press. “Because if this thing comes out – that we are a sick, ill, damaged nation because of government policy constantly passing the buck – it could lead to a flurry of law suits.”

That seems an ever-more likely outcome. What emerges in Don MacAuley’s article is that, in full knowledge of the risk of poisoning our infant population, the Irish authorities have continued to facilitate the overexposure of hundreds of thousands of bottle-fed babies to fluoride.

Meanwhile, in a response to questions posed by Hot Press, the Department of Health has promised a review of the impact of fluoride on human and environmental health in Ireland.
“Two assessments are planned,” a spokesperson told Hot Press. “A review of evidence on the impact of water fluoridation at its current level on the health of the population and on the environment will be conducted by the Health Research Board on behalf of the Department of Health in 2014.”

No detail is provided in relation to how this review will be conducted, what evidence will be assessed, or whether international studies will be taken into account. The fear is that what is intended is another whitewash, specifically designed to bolster the State’s position, in defending any cases taken against it, including the one already being taken by Aisling FitzGibbon.

The Department also tells us that “a review of general health databases is planned to be supported by a public health specialist.”

However, as Don MacAuley’s accompanying report confirms, who is doing the review and how it is approached is vital. Anti-fluoride campaigners will be dismayed to see that the research is being carried out by one of Ireland’s long-time advocates of fluoridation, Professor Denis O Mullane.

“At present,” the spokesperson added, “the Department is collaborating in a University College Cork-led research project, ‘Fluoride and Caring for Children’s Teeth’ (FACCT) which will specifically examine the oral health status of children and inform national policy. The study will consider the impact of changes on the oral health of children, following policy decisions relating to toothpaste use by infants and young children made in 2002 and the reduction in the level of fluoridation in drinking water in 2007.”

Sceptics will point immediately to the title of the study, which presumes a connection between fluoride and ‘caring’. They will also be perturbed at a statement made in the answers provided to Hot Press. In advance of any study or review, we are emphatically told that “the Department does not accept that there is a huge amount of scientific evidence stacking up against the safety and effectiveness of water fluoridation.”

If that is already decided, then it is not worth wasting more public money on any review.

Fluoride in our water - The controversy.


Published in Meath Chronicle 22/10/2013

We drink it every day without a moment´s thought but the Irish state has been dosing our tap water with chemical fluoride for decades.  Back in the 1960s, some scientists believed that by adding fluoride to drinking water they could reduce tooth decay. However, there is a growing controversy that this medication of the Irish population, whether we want it or not, is outdated and dangerous. After all fluoride is a toxic substance, found in rat poison and pesticides. The Food and Drug Administration recognised its toxicity in 1997 when it required by law that all fluoride toothpastes in the United States carry a poison warning – "If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately".

Government dentists contend that the levels of fluoride in our drinking water are so low that there is no risk of poisoning. But how do you control such levels when you are prescribing a medicine by thirst? Before I prescribe a medication for a patient, I know the patient's age, their medical history, and whether they have an allergy or not. All this information is taken into consideration before writing a prescription. In water fluoridation, you know nothing about the patient, whether they are taking other drugs, nor if there is an underlying medical condition, and very importantly, you´ve no idea whether that individual is allergic to fluoride or not.

In fact, not only do the government not know this information, they don´t care! Section 6 of the Health Act 1960 that allows fluoride in our water also required successive health ministers to carry out health studies. In nearly fifty years, not one study has been completed. In light of the scientific controversy linking water fluoridation to serious health conditions such as bone cancer, hip fracture, irritable bowel syndrome and decreased IQ in children, Micheál Martin set up the Fluoridation Forum in 2000. Unfortunately, it was a wasted opportunity made up with the same government dentists who have built their careers on fluoride. The only positive aspect was the involvement of the Food Safety Authority of Ireland (FSAI) who studied the fluoride intake of bottle-feeding infants. Due to their small body weight, infants consuming tap water in their feeds were receiving up to seven times the safe limit for fluoride; and even more shockingly 200 times the levels found in breast milk.


The FSAI concluded, “the precautionary principle should apply and recommends that infant formula should not be reconstituted with fluoridated tap water”. This was the end of fluoridation in Ireland; either breastfeed or buy bottled water to feed your newborns, the prescription by thirst would be fluoride´s final downfall. But the report never saw the light of day. Realising the significance for fluoridation, the government forum buried the report. And next year, the same government will fix meters to our taps, they will expect us to pay to be poisoned by fluoride, as if we haven´t paid enough over the last 49 years.

Fluoride - The Inside Story


Inside Story: Panacea or poison?

 1 September 2013 by John Roberts Published in Sunday Business Post.

If you swallow more than a tiny "pea-sized" amount of fluoride, you are advised to contact a "poison control centre immediately".
Fluoride, the chief ingredient in toothpaste - a product most of us swill around our mouths with abandon twice a day - is highly poisonous. In fact, according to a Department of Health report, brushing your child's teeth at night could be a brush with death. "Swallowing as little as one-quarter of a tube (of fluoride toothpaste) may be life threatening for a one-year-old child," the Department warns, adding that a single tube of toothpaste has enough fluoride to kill a child up to about age 12.
In the US, all fluoridated toothpastes must carry a "poison warning". If you swallow more than a tiny "pea-sized" amount, you are advised to contact a "poison control centre immediately".
But there are no poison warnings on toothpaste in Ireland. A special Department of Health committee decided against introducing them here. "I think putting poison warnings on it is taking things a bit too far," said one of its members.
The truth is, if the government did sanction poison warnings on toothpaste, it would have some tricky questions to answer about what it's doing to our water.
Ireland is now the only country in Europe with a national policy of adding fluoride to the public's drinking water supply. By US reckoning, it is added at toxic levels. A glass of Irish tap water has the same dose of fluoride as a 'pea-sized' amount of toothpaste. Bizarrely, we are advised to spit out the toothpaste, to avoid fluoride's toxic effects. However, we are told that drinking the glass of fluoridated water - in unlimited quantities - is good for you. So which is it?
It is said that water fluoridation reduces tooth decay. However, 98 per cent of Europe - some of the most advanced nations in the world in healthcare terms - have rejected the practice. Many have done so due to health concerns. A recent European Commission report on the issue declared that "fluoride is not an essential element for human growth and development". On July 29, Israel became the latest country to ban the addition of fluoride to its water.
............................
A cumulative poison
Of more concern for Ireland is the source of the fluoride in our water. The ingredient in toothpaste is pharmaceutical grade sodium fluoride. The fluoride added to water, at a rate of one part per million (1ppm), is a much more toxic industrial grade chemical called hydrofluosilicic acid. A highly corrosive acid, it is mainly sourced as a waste product of the phosphate fertiliser industry.
Hydrofluosilicic acid has never been tested for safety on humans. Neither has it ever been proven to reduce tooth decay. Unsurprisingly, then, the only medicinal substance disseminated to 73 per cent of Irish people daily, claimed to reduce an oral disease, remains unlicensed by the Irish Medicines Board.
Fluoride is also a cumulative poison, because the body retains 50 per cent of all it ingests. And if it's in the water supply, it's in everything made from that water too. You get a dose of fluoride every time you drink a cup of tea, coffee, a diluted drink, or any beverage produced from the public mains. It's in your soup, and your boiled potatoes. It's even in infant formula made up for fragile newborns. And babies and young children are most at risk as their bodies retain up to 90 per cent of ingested fluoride. According to the European Commission's 2011 report, Irish children are getting unsafe doses of fluoride every day.
Hip fractures, cancer, arthritic complaints, thyroid impairment and neurological problems have all been linked to fluoride in water. It even damages tooth enamel - the very thing it is put in the water to prevent.
As we approach 50 years of fluoridation in Ireland, have its effects in the Irish population been quantified? Worryingly, the Department of Health has no convincing answers to the effect of its water fluoridation policy, or to many other troubling questions related to this controversial practice.
According to the US National Research Council, the practice of fluoridating water supplies has been the subject of controversy since it began.
Initially a post-war US public health experiment, the idea to add fluoride to public water supplies met with fierce resistance. "Fluorides are known protoplasmic poisons," warned the American Medical Association. Although the experiments were aborted in 1950, the US Public Health Service rushed to fluoridate the entire US anyway. It sparked a major backlash and a bruised US government was forced to change tactics and begin a major push for international approval.
Ireland was the first European country to embrace the measure. The Health 'Fluoridation of the Water Supplies' Act was introduced to the Dáil in 1960 by the Fianna Fáil Minister for Health, Sean MacEntee. It was a deeply divisive bill and opposition health spokesperson Richie Ryan labelled it "one of the most repulsive pieces of legislation which has come before the Dáil".
"Frankly, I was worried," says Ryan. Now aged 84, the former solicitor, MEP and minister for finance has been revisiting his original concerns.
"There was a considerable amount of worrying scientific and medical evidence raising queries about the long-term effects of fluoride. If it was going to affect teeth, then it was going to affect the entire human skeleton. And very little research had been done on that," he says. "You are medicating the entire population for a lifetime, in order to confer a limited benefit on children up to 12 years of age. It's a clumsy treatment at best."
The young Fine Gael TD successfully forced through a late amendment to the 1960 Health Act, stating that "it shall be the duty" of future health ministers to carry out health studies. Fifty years on, no such general health studies have ever been conducted by the Department of Health.
"They don't want to be found in the wrong," says Ryan, of the Department's inaction. "No department of state ever wants to admit that what they have done is wrongful. Once they have an adopted line, they'll defend it to the last."
A failed Supreme Court challenge by Dublin woman Gladys Ryan (no relation) in the early 1960s, with Ryan leading the plaintiff's legal team, delayed the introduction of fluoridation here for three years. However, Dublin's fluoride taps were finally turned on in July 1964, just over 49 years ago.
..........................
Rejection in Europe
In Europe, water fluoridation has been defined by trepidation, aborted trials and outright rejection. Leading scientists fought its introduction. "Fluoridation goes against all principles of pharmacology - it's obsolete," says doctor Arvid Carlsson, a Nobel Laureate in Medicine who advised the Swedish government to reject the practice.
While fluoridation is compulsory by law in Ireland, it is prohibited by law in the Netherlands. Dutch fluoridation trials were halted in 1976 when adverse health effects emerged in the test towns. Even other parts of Ireland rejected it, when 25 out of 26 councils in the North voted against its introduction in 1996. Thus, apart from some local schemes in England and Spain, Europe's water remains fluoride free.
According to Ryan, fluoridation rejection across Europe went virtually unnoticed in Ireland. "The Department of Health issued bulletins if any country in the world introduced fluoridation. They never issued a bulletin when it was rejected."
Today, the US accounts for over half of the world's artificially fluoridated population. And the measure continues to divide the medical community there. In 1998, a union representing 1,500 scientists and other professionals at the US Environmental Protection Agency called for its immediate cessation. "Our members' review of the body of evidence over the last 11 years . . . indicate a causal link between fluoride/fluoridation and cancer, genetic damage, neurological impairment and bone pathology," it said in a statement.
Just nine other countries worldwide fluoridate more than 50 per cent of their water supplies, and the practice is on the retreat. In the last year, vast regions across Australia and Canada have voted fluoridation out. Israel has followed suit.
Major scientific reviews are now saying that the promises that water fluoridation is "safe and effective" are not backed by hard science.
In 2006, the US National Research Council (NRC) conducted the most comprehensive review yet on the safety levels of fluoride in water. The report "should be a wake-up call", said one of its authors. Thyroid impairment, moderate skeletal fluorosis (arthritis), and impaired glucose tolerance (type 2 diabetes), can all be caused by the levels of fluoride consumed in artificially fluoridated communities at 1ppm, said the NRC report.
A European Commission report on water fluoridation, published in 2011, re-affirmed that "there is continuous controversy over the benefit of fluoride and (fluoridation)". The EC's Scientific Committee on Health and Environmental Risk (SCHER) said the evidence that swallowing fluoride in water reduced decay was not convincing.
While it's true that decay rates have plummeted in Ireland since the 1960s by up to 70 per cent, tooth decay has declined at similar levels in virtually every other industrialised country worldwide, without the aid water fluoridation. World Health Organisation statistics reveal that most of our non-fluoridated European neighbours now have better teeth than in fluoridated Ireland.
The European Commission specifically dismissed the role of water fluoridation in its 2011 SCHER report. Decay declines have been achieved "independent of the fluoridation policies across the EU Member States" it stated. Other reviews have also debunked fluoridation's alleged decay-defying properties.
"Given the level of interest surrounding the issue of public water fluoridation, it is surprising to find that little high-quality research has been undertaken," concluded a major review at the University of York in 2000.
The truth is that decay has declined globally, including here in Ireland, due to many factors: changes in nutrition, improved oral hygiene, better education, as well as fluoridated toothpaste.
Senior Department of Health officials have admitted in the past that because of these factors, most Irish people don't need fluoride in their water. However, today, the Department's position seems to have hardened.
"Children in Ireland have poor tooth-brushing habits," a Department spokesperson told The Sunday Business Post. Irish kids also ate lots of "foods and drinks sweetened with sugar", it added. Because of these factors, water fluoridation must continue for everyone.
Evoking Ryan's description of a "clumsy treatment", it's not clear if the children drinking too many sugary soft drinks - the very target of fluoridation - are therefore even drinking the medicated tap water.

'Fluoridation works'
The Irish government continues to cling to the mantra that "fluoridation works". However, along with international dental authorities, the Department concedes that the original logic for fluoridation is now obsolete.
Back in the 1940s, they thought fluoride had to be ingested, to be incorporated into a child's developing teeth, making it more resistant to decay.
But they got it wrong. Recently, they've conceded it only works "topically", in the mouth, such as via toothpaste, which you spit out. Dental authorities, meanwhile, say ingesting fluoride systemically causes harm.
Numerous reviews, including the York Report, have said that fluoridation at 1ppm causes toxic effects in 50 per cent of people. And remarkably, these effects show up in the very organ fluoride is supposed to be protecting: the teeth. The condition is called dental fluorosis.
...........................
Dental fluorosis
Dental fluorosis is systemic fluoride poisoning of the teeth. It's a sign that the normal development of tooth enamel was impaired, and it is only caused by fluoride.
Fluorosis appears as white lines on teeth, and can cause discoloured stains. At severe levels (which can result from swallowing toothpaste), the teeth are pitted and chipped. The tooth enamel is totally destroyed. Severe enamel fluorosis is a toxic effect that causes structural damage to the tooth, according to the US NRC report in 2006. And fluorosis is on the rise in Ireland, according to a report from the Department of Health.
With this evidence that fluoridation damages teeth, far more convincing than evidence of any benefit, international experts say it's time to stop.
"Litigation is inevitable. Inaction in the face of evidence could be considered negligent," said Dr Hardy Limeback, past president of the Canadian Association of Dental Research, when he addressed TDs at the Oireachtas Health Committee in 2000. But the existence of fluorosis raises much more troubling questions about water fluoridation.
If 1ppm damages your teeth, the only visible part of your skeleton, surely it's damaging your bones too? And if ingesting fluoride via toothpaste can poison every organ in the human body, almost instantly, does ingesting fluoride via water have the same effects, just over a longer period of time? The evidence is alarming.
Fluoride in water has been linked to bone defects, neurological disorders, cancer, genetic damage, gastrointestinal issues, thyroid problems and arthritic complaints. There are now more than 1,000 scientific studies on the subject. The research incites heated debates, for a simple reason; the amount of fluoride known to cause this damage is minuscule.
Most therapeutic substances have a margin of safety of at least ten. This means that people can consume ten times a "recommended dose" without suffering ill effects. But based on dental fluorosis, fluoride's safety margin is less than one. And of even more concern, catastrophic health effects are seen at levels well below the normal "no effect" safety margin of ten.
An edition of the British Medical Association's New Guide to Medicines and Drugs states that just 8ppm can wreak havoc with the entire human body, causing bone disorders and degenerative changes on the kidneys, adrenal glands, central nervous system and reproductive organs. That is just eight times Ireland's recommended concentration.
The World Health Organisation admitted in 2008 that skeletal fluorosis (with adverse changes in bone structure) may be observed when drinking water contains 3-6mg per litre, just over three times Ireland's optimal level.
Studies indicate that thyroid function can be lowered at just 2.3 ppm. IQ in children may be lowered at levels as low as 1.9ppm. Other studies indicate hip fractures in the elderly may be increased at 1.5ppm, and tripled at over 4.3ppm.
This lack of safety margin concerned the US National Research Council. Because fluoride is freely available in the water supply, there's no controlling the dosage. It's prescribed by your thirst. Therefore anyone drinking fluoridated water at 1ppm, can easily ingest the same dose of fluoride as people drinking 4ppm, a concentration known to pose serious health risks.
"In other words, any effect seen at 4 mg/L is probably going to occur in some people at 1 mg/L, in the people with highest water consumption or in people with impaired fluoride excretion, but this might easily be missed in the sample sizes typically used in studies," says NRC panel member Professor Kathleen Theissan.
The NRC report also warned that there is little understanding of the fluoride levels which cause the early stages of crippling skeletal fluorosis. These are marked by "joint pains, calcification of ligaments, and arthritic complaints", all symptoms widely prevalent in fluoridated communities. Other effects of fluoride's toxic potentialities are becoming disturbingly clear, said the NRC report.
"Fluoride appears to have the potential to initiate or promote cancer," it said. It can damage the brain, too, with as yet unknown consequences. The report discussed the possibility that fluorides act to increase the risk of developing Alzheimer's disease.
The NRC's call for more research has been ignored by fluoridating countries, including the US. The report has been dismissed as irrelevant in Ireland. "There is no scientific evidence that water fluoridation causes any ill medical effects," the Department of Health told The Sunday Business Post.
However, the Department refuses to do its own research to back this statement up, despite the 1960s Health Act stipulating this take place. When asked why no general health research has been done in 50 years, the department said it "uses information from across the globe in order to assess the health impact of water fluoridation".
According to the NRC's Dr Hardy Limeback: "The evidence has convinced me that the benefits of water fluoridation no longer outweigh the risk [of fluoridation]."

Death knell
An expert committee set up in 2000 by the then health minister, Micheál Martin, to look into water fluoridation found no evidence of fluoride's toxic effects when it reported in 2002.
The forum's findings contrasted sharply with that of a Belgian Health Ministry report, published weeks previously. It found that ingesting fluoride causes osteoporosis and neurological disorders. "Fluoride is a slithering poison, it slowly creeps into the brain," said the then Belgian health minister Magda Aelvoet, as she announced a ban on fluoride supplements in July 2002.
The Irish Department of Health's forum did, however, admit that we are getting too much fluoride. It recommended turning our fluoride taps down from 1ppm, to a safer 0.8ppm.
The forum also looked at the issue of having babies drink infant formula made from fluoridated tap water. Firstly, babies don't need any fluoride - they have no teeth. But as they drink three to four times more liquid than adults, relative to their size, they get three to four times fluoride's toxic effects. Also, babies can't excrete fluoride, so 90 per cent of it stays in their body. With one of the lowest breastfeeding rates in the world, this is a uniquely Irish public health concern.
An independent report submitted to the forum on the topic should have sounded the death knell for fluoridation.
"The Scientific Committee agrees that the precautionary principle should apply and recommends that infant formula SHOULD NOT be reconstituted with fluoridated tap water," said the report by the Food Safety Association of Ireland (FSAI). Irish newborns are getting "up to seven times the safe dose," it claimed. However, the recommendations were excised in the forum's final report.
Dr Don MacAuley, spokesman for Irish Dentists Opposing Fluoridation, believes the forum buried the Food Safety Authority's damning risk assessment. An Oireachtas Health Committee hearing on the issue in July 2003 yielded no clear answers on what happened. However, forum members admitted that the original FSAI finding spelled the beginning of the end.
"It probably would have meant an end to water fluoridation, or at least a serious reappraisal of it," Dr Joe Mullen told the Dáil committee. "If further evidence emerged that this was a problem, it would be a very serious blow for water fluoridation."
Further evidence has now emerged. In 2006, the National Research Council concluded that babies fed infant formula made from fluoridated water, are exceeding safe intake levels. In response, numerous US public health authorities, including the American Dental Association, advised that tap water should not be used to reconstitute infant formula.
In 2011, the EC's SCHER report said that even at Ireland's new lower fluoride level of 0.8ppm, Irish children, who are also regular users of toothpaste, are being exposed to unsafe fluoride levels in tap water. "For younger children (1-6 years of age), the upper tolerable intake level (UL) was exceeded when consuming more than 1L of water at 0.8 mg fluoride/L (mandatory fluoridation level in Ireland)," said the SCHER report.
It also reaffirmed that formula-fed babies in Ireland were exceeding the safe dose, as set by the US Institute of Medicine. "For infants up to six months old receiving infant formula . . . this amount is 200 times higher than the amount found in breast milk," said the SCHER report.
By its own admission, this evidence that fluoridation gives our most vulnerable citizens unsafe levels of fluoride every day should be enough for the Department of Health to stop water fluoridation. Instead, its fluoride promotion unit, the Expert Body on Fluorides and Health, maintains that fluoridated water is still "safe for use in preparing infant formula".
When asked why it has not issued advice to parents as per the US, the Department of Health, which accepts that fluoride works topically, on the tooth surface, and that new-born babies have no teeth, states that "all ages benefit from fluoridation".
It also claims that the controversy on infant formula is based on "inaccuracies and scientifically unfounded connections". It doesn't outline what these might be.

Public health versus public health policy
According to the Irish Dental Association: "The introduction of water charges is sure to provoke interesting debate surrounding water fluoridation." The dentists' representative body describes fluoridation as "the most practical, cost-effective and safe public health measure to control the occurrence of tooth decay in Ireland".
Unfortunately, the Irish public doesn't share its enthusiasm. According to a Dental Health Foundation survey, more than two-thirds of adults are "concerned about fluoride in their water". Almost a quarter are "very concerned", and nearly 90 per cent of submissions to the Forum on Fluoridation were from citizens against it.
Yet no political party has ever represented the electorates' views on the issue. Both government parties, Fine Gael and Labour, questioned fluoridation in opposition, but today seem in no mood to rock the boat. Meanwhile, Labour's Alex White, the junior health minister, has been actively defending the practice.
With Micheál Martin - who ratified its continuation in 2002 - now leader of Fianna Fáil, a challenge to the status quo has been left to Sinn Féin. The party's environmental spokesman, Brian Stanley TD, recently published a bill to repeal the 1960 Health Act. "This is not a party political issue, but an issue of public health. I will be seeking cross party support for this bill when we debate it in the Dáil," says Stanley.
Others are also actively campaigning for its cessation. Tralee native Aisling Fitzgibbons is planning a High Court case against the state later this year, to try to ban the measure. Environmental scientist Declan Waugh has produced research showing that Ireland tops the league table on many ill effects linked with fluoride ingestion, including cancer and neurological disorders.
Journalist Iva Pocock has recently asked the EU Petitions committee to declare hydrofluosilicic acid in breach of the EU's Medicinal Products Directive.
Irish Water, the new semi-state, will install 27,000 water meters a month between now and the end of 2016. As it does, it will be acutely aware of the absurdity of dispensing medicine through a public utility; 99.9 per cent of the Department of Health's precious fluoridated water is either lost in underground leaks, used by industry or flushed straight down the national drains as domestic waste. Virtually all of it bypasses our teeth. Stopping fluoridation today would save the state €4 million a year.
Studies from Finland, former East Germany, Cuba and British Columbia have shown no increase in decay rates in teeth after cessation of water fluoridation. In fact, if anything, tooth decay continued to fall after it was stopped. "The few studies of water fluoridation discontinuation do not suggest significant increases in dental caries," said the European Commission's SCHER report in 2011.
Here in Ireland, this doesn't leave us with much to smile about.
