Dear Dr. Walensky,
First, let us congratulate you on your recent appointment as Director of the CDC. Like millions of Americans and others we wish you every success in your leading role in the fight against the COVID-19 pandemic.
With respect to this emergency we believe that it is critical that everything possible be done to maintain the public’s trust in the credibility of your agency. Hence the reason we are writing to you today.
We write as professionals who have experience in a wide range of arenas including academic research, medicine, dentistry, public health, public utilities, law, journalism, the environment and environmental health.
Most of us have spent many years involved in the debate over water fluoridation and have carefully studied the science dealing with the toxic effects of fluoride.
Neurotoxicity of fluoride
Of particular interest to us has been an ever-growing body of studies, beginning in the mid-1990s, that indicate that fluoride is neurotoxic.
To date, more than 67 human studies, most from endemic fluorosis areas in China, have associated lowered IQ with fluoride exposure. Promoters of water fluoridation have dismissed the relevance of these studies a) because of methodological limitations and b) because many (but not all) of these findings occurred at higher fluoride concentrations than those used in water fluoridation programs. Nevertheless, there has been general agreement that the findings have been remarkably consistent (Choi et al., 2012).
A very significant improvement in the quality of these studies occurred in 2017, when the first of four NIEHS-NIH funded studies were published (Bashash 2017 and 2018; Green 2019; and Till 2020). These were rigorously designed studies for which many potential confounders were controlled. In addition, fluoride exposures and cognitive outcomes were based on measurements made at the individual (as opposed to community) level. For the first time, the studies included measurements made in pregnant women and their offspring. This was important because fluoride is known to cross the placenta.
Most importantly, the fluoride exposures in these studies were at levels commonly experienced by pregnant women and children in fluoridated communities in the USA. The weight of evidence now strongly suggests that fluoride is capable of damaging both the fetal and the infant brain at very low levels.
Presumably, such findings have been jarring for those who have enthusiastically supported water fluoridation and who have hitherto believed that the only harm caused by fluoride for those drinking fluoridated water was mild dental fluorosis (disrupted enamel formation which can appear as white spots or staining on teeth). Needless to say, damage to the developing brain is far more serious than damage to the tooth enamel.
The leaders of the Oral Health Division at the CDC appear to be in a state of denial on fluoride’s neurotoxicity. This was clearly illustrated at a recent event, which has triggered this letter to you.
CDC Oral Health director’s false statement
At a recent webinar (March 11, 2021) organized by the American Association of Dental Research (AADR) and the National Institute of Dental and Craniofacial Research (NIDCR), CDC Oral Health Director Casey Hannan responded to a question submitted to him about a week before the meeting. He claimed that the recent NIH-funded studies, discussed above, were conducted at levels much higher than currently used in water fluoridation programs. This answer was false and it is disturbing that it was issued in a prepared statement. A slip-up in an off-the-cuff comment might have been excusable.
Here is his exact quote:
Contrary to Hannan’s assertions, the NIEHS-NIH funded studies were carried out at doses currently experienced in fluoridated communities. Specifically, these studies were either done in communities fluoridated at the CDC’s recommended level of 0.7 ppm (mg/L) of fluoride in water (Green 2019 and Till 2020) or in communities experiencing equivalent fluoride doses as measured in mother’s urine (Bashash, 2017 and 2018).
Hannan might simply claim that he was doing his job in carrying out the Oral Health Division’s mission of promoting water fluoridation as a method of fighting tooth decay in children. To our point, it is the way that the CDC’s mission has been carried out over so many years that concerns us. It has been highly biased and Hannan’s blatant mis-statement is just the latest example. Many of Hannan’s predecessors have repeatedly claimed that fluoridation is “safe and effective” without producing the studies that demonstrate safety and ignoring those that show harm.
The Oral Health Division’s biased promotion of fluoridation
We believe CDC Oral Health Division personnel have seen their task as simply promoting the benefits of fluoridation, and have repeatedly downplayed health risks posed by swallowing fluoride. We believe that this situation, in part, is due to the fact this small division of about 30 people has no specialists in tissues other than the teeth. None are specialists in neurology, neurotoxicity, bones, the thyroid gland, the kidneys, and other systems that have been found by the National Research Council to be affected by fluoride (NRC 2006). The Oral Health Division appears to employ no toxicologists.
While fluoridation is instigated at the municipal level (often against the express wishes of many citizens), local decision makers are often heavily influenced by the CDC’s enthusiastic promotion of this practice. Indeed, hardly a day goes by without some local official somewhere stating that the CDC considers fluoridation, “One of the top public health achievements of the twentieth century” (CDC, 1999).
The CDC’s failure to adequately consider health risks posed by fluoride
We are concerned that the CDC’s failure to adequately consider the health risks posed by fluoride has left a gaping hole in CDC’s understanding of the consequences of fluoridation.
The loss of IQ points has lifelong consequences. For the individual, it has been estimated that a loss of one IQ point would reduce lifetime earnings by $18,000 (Grandjean et al., 2012). The losses observed in the NIEHS-NIH funded studies range from 3 to 9 IQ points for an increase of 1 mg/liter of fluoride in water and thus an estimated drop of 2-7 IQ points drop for a community fluoridated at 0.7 ppm. To put that into perspective, at the population level a shift downwards of 5 IQ points halves the number of very bright children (IQ >130) and increases by 57% the number of children needing special care (IQ <70). Both changes have enormous social and economic ramifications for the USA.
In addition, a major prospective cohort study from Sweden demonstrates a higher risk of hip fractures in post-menopausal women associated with long term exposure to natural fluoride at levels in water in the same range as America fluoridates its water [Helte et al., 2021].
Also, recent epidemiological studies conducted in the United States, using individual biomarker measures of fluoride exposure, have found an association between low to moderate fluoride intake and impaired renal and hepatic function [Malin et al., 2019], increased risk of hyperuricemia [Wei et al., 2021], as well as adverse effects on reproductive endocrinology in U.S adolescents [Bai et al., 2020].
Need for a pause in CDC’s promotion of fluoridation and a resolution of the safety issues surrounding fluoridation
When you and your staff have examined these recent findings, we hope that you will agree that there is an urgent need to put a pause on further promotion of fluoridation by the CDC – at least until these scientific issues have been very carefully reviewed by qualified CDC personnel who have had no prior association with efforts to promote this practice.
To this end, and looking even beyond fluoridation, we urge that you institute a special committee, or even a new division at the CDC to regularly review the scientific underpinnings of public health practices. Such reviews would look at neurotoxic and other effects that, in the context of public health policy, could expose the whole population to unacceptable risks. Reviews should be comprehensive and rigorous and be submitted to Congress on an annual basis.
As far as the Oral Health Division is concerned we believe that until the issue of these serious health threats has been resolved, the division should focus its resources on ways of fighting tooth decay without exposing the population to fluoride in the water supply. As you know, most countries promote dental health without fluoridating their water.
There is a clear need to focus on dental care for low-income families, but we need to do so without compromising our children’s mental development. Federal, state and local governments need to provide better access to preventive dental care and early education for better diet and dental hygiene. The latter has proved very successful in Scotland (see the ChildSmile program).
Seen as a way of reducing inequities in dental care, fluoridation claims a noble purpose. Unfortunately, the effort has seriously backfired. Lowering IQ with fluoride exposure adds a further handicap to the mental development of children from low income families, especially those living in the inner city. The latter are already contending with a higher burden of lead pollution (see Fluoride Action Network’s 2015 report submitted to the Environmental Justice Interagency Working Group).
Immediate warnings needed for pregnant women and parents
As an immediate step, we urge you as Director of the CDC, to issue warnings to both pregnant women and parents of formula-fed infants to avoid fluoridated water and other sources of fluoride. A Cochrane Review in 2017 concluded that ingestion of fluoride during pregnancy conferred no dental benefit, so this is a situation where risks are being taken for no proven benefit. This point was made by two leading public health researchers (Bruce Lanphear MD, MPH, and Christine Till, PhD) along with Linda Birnbaum, PhD, former Director of the NIEHS/NTP (2009-2019), in an editorial published in Environmental Health News, Oct 7 2020.
Please put protecting our children above protecting an outdated practice
In summary, Dr. Walensky, we sincerely hope that the CDC under your new leadership will acknowledge the strong scientific evidence of fluoride’s neurotoxicity (and other health effects) and that you will put the welfare of our children and the overall health of our people at the forefront of the agency’s agenda.

I have spent a decade of efforts in two non-profits to educate lawmakers and officials about the tragic harm fluoridation causes vulnerable populations. If Dr. Welensky witnessed the suffering my son goes through when he is inadvertently exposed to fluoride (fortunately now rare because of my painstaking and expensive precautions) she would not allow the CDC to promote this practice for another single day. She would see an otherwise happy young man brought to his knees in pain.”

I tend to take a broader perspective of the issues surrounding water fluoridation and despair at the selective use, and misuse, of the so-called science. In my view water fluoridation:
- is unnecessary, with questionable legality
- sets a precedent of using the public water supply system as a vehicle for delivering medication to individuals
- breaches the fundamental rights of an individual to consent to medical treatment
- is surrounded by uncertainty over the benefits
- exposes populations to inadequately safeguarded harmful risks.”

My water treatment engineering and operations experience began revealing twelve years ago, and very disturbingly, that fluoridation has been an egregious violation of the spirit and intent of the federal SDWA and the public trust, if for no other reason than it typically and knowingly allows for legally contaminating our tap water with lead and arsenic, as well as fluoride. Lead and arsenic are recognized and regulated contaminants with their respective MCLGs of zero. I have seen Certificates of Analysis showing arsenic up to 51 ppm in the fluorosilicic acid (FSA) being shipped from the fertilizer industry supplier. FSA is the most common fluoridating chemical agent added to the public drinking water at treatment plants in the US.

I was not able to perform daily tasks. After diagnosis, by avoiding city Fluoridated tab water and fluoridated dental products, my symptoms started to improve and after a few months of avoiding these sources I came out of disability. However, to this date, drinking a glass of fluoridated tap water or taking one shower with fluoridated tap water (at 0.7ppm) will trigger all the above-mentioned symptoms.

“From 1977-1982, I was involved in advising a committee investigating a proposition to introduce water fluoridation into Sweden. I authored several papers on fluoride submitted to governmental agencies and politicians. I worked together with, among others, two Nobel laureates: professor of biochemistry Hugo Theorell and professor of pharmacology Arvid Carlsson. Theorell was very familiar with fluoride’s inhibiting action of many enzymes in the human body. Carlsson pointed out the fundamentally erroneous method of distribution of a pharmacologically active substance without having control of the dose to individuals. In 1982, addition of fluoride to water, other beverages or any kind of food was declared unlawful in Sweden.
“I also advised opponents to an old ongoing fluoridation study in Finland, where two cities with equal socioeconomic levels were compared: Kuopio with artificial fluoridation and Jyvaskylla, which had very low levels of fluoride in its drinking water. This action finally led to a stop of fluoridation in Finland. Interestingly, a study performed afterwards comparing the dental status in Kuopio and the control city Jyvaskylla showed that after 33 years of public water fluoridation in Kuopio, the only difference in caries status was the presence of more filled first molars in the fluoridated Kuopio!

“My decades of illness began during my second pregnancy in 1981. My doctor told me that some pregnancies are just more difficult than others. I almost lost my child, more than once. It took me the better part of two years to figure out that the stomach troubles, rashes, and other symptoms that plagued me and my children were connected to city water. It took me another 32 years to figure out that my arthritis, kidney pain, liver problems, and daily dizzy spells were because my high-quality water filter wasn’t sufficient to remove enough fluoride. The PHS knew in 1956 that the ‘allergic’ population were highly vulnerable to these effects (Feldman 1956; Feldman & Kosel 1961) but endorsed fluoridation policy anyway. My city began fluoridation on July 1, 1981 during my pregnancy. My son who has an IQ of 130 dropped out of high school because of frustration over his learning disabilities, disabilities consistent with those reported in NIH sponsored studies on the neurodevelopmental effects of prenatal exposure to fluoride. My doctor back then refused to examine the hives my children and I had, and yelled me out of his office when I asked him if something in the water could have been making us ill, shouting, “Who put you up to this? I’m sick and tired of people telling me there is something wrong with the water!” He was the chair of the Board of Health who ordered the fluoride into the water. He knew, I didn’t – not then, but he knew. It’s been 40 years this summer since my city began poisoning my family. It’s been 65 years since HHS knowingly began poisoning families like mine. Now you know. Stop it!”

“I became a Member of the Australian and New Zealand College of Psychiatrists in 1985 and have taken an interest in the toxicity of fluoride since 1988 after reading Fluoride: the freedom fight by Dr. Hans Moolenburgh (Edinburgh: Mainstream Publishing; 1987). In about 1991 at a conference of the New Zealand Branch of the Australian and New Zealand College of Psychiatrists, I presented a paper on one of my patients who suffered a psychotic illness after exposure, in a commercial glass house, to a fluoride-containing glass cleaning spray. I subsequently wrote a review of the psychopharmacology of fluoride which was published in International Clinical Psychopharmacology in 1994 (https://pubmed.ncbi.nlm.nih.gov/8056997/.
“For some time, I have supported the publication of peer-reviewed scientific papers on fluoride by becoming, in 1994, a co-editor of Fluoride: Quarterly Journal of the International Society for Fluoride Research, and, in 2013, after the death of Professor Albert Burgstahler, the editor-in-chief. In 2008, I authored a book describing fluoride toxicity (Fluoride fatigue. Fluoride poisoning: Is fluoride in your drinking water—and from other sources—making you sick? Dunedin, New Zealand: Paua Press; 2008. Available from: untitled (fluorideresearch.org)). The International Society for Fluoride Research is a non-political organization which does not take a position on water fluoridation and publishes research on all aspects of fluoride based on scientific merit and my support for this letter reflects my personal view that the fluoridation of community water supplies, to achieve drinking water fluoride levels of approximately 0.7 mg/L, is detrimental to the developing brain. The results from two well-designed prospective studies, from Mexico (Early Life Exposure in Mexico to Environmental Chemicals, ELEMENT, by Bashash et al.) and Canada (Maternal-Infant Research on Environmental Chemicals, MIREC, by Green et al.), show that the benchmark concentration level (BMCL) for a benchmark response (BMR) of 1 IQ point for the maternal urinary fluoride level is about 0.2 mg/L. Preventing fluoride-induced developmental neurotoxicity in children by lowering the dietary fluoride intake to the estimated safe level for pregnant women and children may not be easily achievable but a start could be made by relatively simple measures such as avoiding fluoridated water (See: untitled (fluorideresearch.online).”

“I have been campaigning against fluoridation since the 1980s, when the measure was first proposed in my home town of Hull, Yorkshire. I oppose fluoridation on the grounds that it is linked to a growing number of serious health conditions; that it is compulsory medication without consent; that it pollutes water systems and damages natural ecosystems; and that it is neither necessary nor cost-effective in preventing dental caries.”

“I supported fluoridation practices for many years believing the dental community’s claim that fluoride was a natural “nutrient,” that the appropriate studies had been completed and that there were no known adverse side-effects. Having completed an undergraduate degree in toxicology and a clinical doctoral degree I had the opportunity to undertake my own review of the scientific literature on fluoride. To do this I had to get passed my knee jerk resistance to question what I have since found out to be just dogma. The current and even passed scientific research shows without question that fluoride is toxic to brain cells and to the endocrine system. To continue supporting this outdated practice of water fluoridation is simply unjustifiable in light of our current science-based understanding of the toxic effects of fluoride ingestion.”

“I have been a Dental Hygienist for 47 years. I was taught at school that water fluoridation is very beneficial for the public. I have since learned that fluoride is actually “hexafluorosilicic acid,” which is a toxic waste bi-product of the phosphate fertilizer industry. We were not taught the science about artificial water fluoridation. We were not taught that fluoride is a neurotoxin and no amount is safe. I do NOT want my children/grandchildren to be continually exposed to water fluoridation knowing that it can and will affect their minds and bodies.”
