US EditionFluoride in drinking water does not negatively affect cognitive ability — and may actually provide benefit, study finds
A U.S. study of nearly 27,000 teens found no cognitive harm from recommended fluoride levels and observed slightly higher high school test scores among exposed youths.
- The new study found robust evidence that young people exposed to recommended levels of fluoride in drinking water performed better on cognitive tests than their peers without fluoride exposure, as noted by Dr. Rob Warren.
- Utah and Florida have banned the practice of adding fluoride to municipal drinking water, following claims by Secretary Robert F. Kennedy Jr. regarding IQ loss due to fluoride.
- The study followed nearly 27,000 individuals and showed that consistent exposure to fluoride correlated with higher high school test scores and did not contribute to cognitive decline as they aged.
- The American Dental Association supports community water fluoridation, considering 0.7 milligrams of fluoride per liter as optimal, while the US Centers for Disease Control and Prevention has not changed its recommendations.

Fluoridated Water Not Linked to Lower Cognitive Abilities: Study
Drinking fluoridated water is not linked to lower cognitive abilities, researchers said in a new study. Students who lived in areas that added fluoride to water tested better in school, John Robert Warren of the University of Minnesota and other researchers said in the paper, published Nov. 19 by Science Advances. “We find robust evidence that young people who are exposed to typical, recommended levels of fluoride in drinking water perform bette…
Fluoridated water linked to better adolescent school achievement
Children exposed to recommended levels of fluoride in drinking water show modest cognitive advantages in secondary school, with no clear evidence of harm to cognitive functioning around age 60, according to researchers at the Institute for Social Research and Data Innovation at the University of Minnesota and multiple collaborating institutions.
Study finds fluoride in drinking water boosts cognition, challenges claims of IQ decline
A new study published by the American Association for the Advancement of Science finds fluoride in drinking water does not impair cognitive abilities and may even boost them. Using test scores from nearly 27,000 Americans, researchers reported that students with full childhood exposure to recommended fluoride levels scored higher than those without, with no evidence of cognitive decline later in life. The findings challenge earlier government re…
