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 fluoride exposure at recommended levels linked to modestly higher high school test scores without cognitive decline later in life.
- 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.

Large-scale U.S. study links water fluoridation to slightly improved cognitive development
Recent findings published in Science Advances provide new evidence regarding the long-term cognitive effects of consuming fluoridated water during childhood. The study suggests that growing up in communities with water fluoridation levels typical of the United States does not harm brain development and may be associated with slightly higher academic achievement in adolescence. These results offer a counterpoint to ongoing debates and legal chall…
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.
