Quoted: Top Scientists On Fluoride’s Risk To The Developing Brain

April 21st, 2021 | Fluoride Action Network

FAN Note: It is vital that pregnant women and parents/carers who formula-feed infants be warned of fluoride’s serious risks to the developing brain.  Pregnant women and infants should not be consuming fluoridated water.  Numerous experts in the field of developmental neurotoxicity have equated the loss of IQ from fluoridation to that from childhood lead poisoning.  They include Bruce Lanphear MD, MPH, Christine Till PhD, and Linda Birnbaum PhD, the former director of NIEHS and NTP.

Loss of IQ has lifelong consequences for the individual, and a profound effect on the social and economic well-being of the nation. We urge our supporters to get this warning into the hands of any scientist, doctor, public health official, educator, media outlet or legislator (at any level) they know.

VIDEO: 12 Quotes from Prominent Scientists on Fluoride’s Risk to Kid’s Brains.


1. “New evidence questions existing policies about the safety of fluoride for babies’ developing brains. Given that safe alternatives are available and that there is no benefit of fluoride to babies’ teeth before they erupt or appear, it is time to protect those who are most vulnerable.” – Bruce Lanphear MD, PhD; Christine Till PhD; & Linda S. Birnbaum PhD in “It is time to protect kids’ developing brains from fluoride.” Environmental Health News (October 7, 2020)

Linda Birnbaum, PhD, Director, National Institute of Environmental Health Sciences and the National Toxicology Program, 2009-2019

2. “It’s actually very similar to the effect size that’s seen with childhood exposure to lead,” says David Bellinger, a professor of neurology at Harvard Medical School and Boston Children’s Hospital. NPR (August 19, 2019)

David Bellinger, PhD,  professor of neurology at Harvard Medical School and professor in the Department of Environmental Health at the Harvard School of Public Health. He is also a Senior Research Associate in Neurology and a Senior Associate in Psychiatry at Boston Children’s Hospital.

3. “You have a situation where there is a clear identifiable risk (neurotoxicity), and a serious one without any offsetting benefit.” – Michael Connett, esq, TSCA Fluoride Lawsuit (2020)

Michael Connett, JD, is a partner at Waters Kraus & Paul in the firm’s Los Angeles office. He is the lead attorney in the ongoing TSCA (Toxic Substances Control Act) lawsuit against the U.S. Environmental Protection Agency on fluoride’s neurotoxicity.

4. “I don’t think anyone disputes that fluoride is a hazard”. – Judge Edward Chen, TSCA Fluoride Lawsuit (2020)

Edward Chen, United States District Court for the Northern District of California, presiding judge of the ongoing lawsuit against the U.S. Environmental Protection Agency on fluoride’s neurotoxicity.

5. “The principal hazard at issue from exposure to fluoridation chemicals is IQ loss.” – Dr. Kathleen Thiessen, TSCA Fluoride Lawsuit (2020)

Kathleen Thiessen, PhD, is President and senior scientist at Oak Ridge Center for Risk Analysis. D Thiessen served on the National Research Council panel that prepared the landmark 2006 review, Fluoride in Drinking Water: A Scientific Review of EPA’s Standards. Dr. Thiessen has authored health assessments on fluoride, and other toxic substances, for the EPA and other federal agencies.

6. “Fluoride exposure during early brain development diminishes the intellectual abilities in young children.” – Bruce Lanphear, TSCA Fluoride Lawsuit (2020)

Bruce Lanphear, MD, MPH, a professor of health sciences at Simon Fraser University in British Columbia. Dr. Lanphear’s groundbreaking research on the neurotoxic effects of low-level lead exposure has shaped regulatory policy in the U.S.

7. “Fluoride is a developmental neurotoxicant at levels of exposure seen in the general population in water-fluoridated communities“. – Dr. Howard Hu, TSCA Fluoride Lawsuit (2020)

Howard Hu, MD, MPH, ScD, a physician-scientist, board-certified in Internal Medicine and Preventive (Occupational) Medicine. Dr. Hu was the senior investigator on an National Institutes of Health-funded study examining the effects of prenatal fluoride exposure on IQ and other neurodevelopmental harm.

8. “IQ losses associated with community water fluoridation are substantial and of significant public health concern.” – Dr. Philipe Grandjean, TSCA Fluoride Lawsuit (2020)

Philippe Grandjean, MD, PhD, is adjunct professor of environmental health at the Harvard School of Public Health. A Danish scientist, he works in environmental medicine and is the head of the Environmental Medicine Research Unit at the University of Southern Denmark. He has led groundbreaking investigations of neurotoxic chemicals, including mercury and fluoride. He is considered a leading expert in the field, having won numerous awards.

9. “We recommend that women reduce their fluoride intake during pregnancy.” – Dr. Christine Till, NPR (August 2019)

Christine Till, PhD, a tenured Associate Professor in the Clinical Developmental Area in the Department of Psychology and Faculty of Health at York University in Toronto, Canada. She is also appointed as an Adjunct Scientist of the Neurosciences and Mental Health Research Program at The Hospital for Sick Children.

10. “I think it’s important to think carefully about putting fluoride into the drinking water. There is a percentage of the population that’s sensitive, and quality of life can be incredibly impacted if fluoride is there.Dr. Amanda Sleeper on Fluoride Hypersensitivity, YouTube (December 2019)

Amanda Sleeper, PhD (Neuroscience/Pharmacology)

11. “There are people who will protect fluoride no matter what the cost, no matter what the evidence says. They will disregard the evidence and continue to say that it is unequivocally safe and effective. We’ve seen this over and over by people who have strong interests in promoting fluoridation.Dr. Christine Till, Excalibur News (October 2020)

Christine Till, PhD, a tenured Associate Professor in the Clinical Developmental Area in the Department of Psychology and Faculty of Health at York University in Toronto, Canada (see more above)

12. “Simply put, fluoride research on neurotoxicity is following the same trajectory as the research on lead’s neurotoxicity from the 1970s to 1990s; namely, as far as early life is concerned there is virtually no safe level of exposure.” – Dr. Paul Connett, Founder of Fluoride Action Network (2020)

Paul Connett, PhD (Chemistry), Professor Emeritus, co-founder and director of the Fluoride Action Network. Co-Author, The Case against Fluoride: How Hazardous Waste Ended Up in Our Drinking Water and the Bad Science and Powerful Politics That Keep It There (Chelsea Green 2010), and author, The Zero Waste Solution (Chelsea Green 2013).
