The American Dental Association (ADA) has reaffirmed its strong support for community water fluoridation, following a recent study in Journal of the American Medical Association (JAMA) Pediatrics that explored the potential link between fluoride exposure and lowered IQ in children. The study, which conducted a meta-analysis of 74 studies, suggested a possible connection between fluoride exposure and reduced IQ. However, the ADA maintains that the study does not provide new evidence to alter current water fluoridation practices.
Dr. Steven Levy, a leading fluoride expert and member of the ADA’s National Fluoridation Advisory Committee, criticized the study’s methodology, calling it “deeply flawed.” He pointed out that the study found no evidence of a connection between fluoride exposure at levels recommended for community water fluoridation and lowered IQ. Dr. Levy also emphasized that the studies included in the meta-analysis examined regions with fluoride levels far higher than those used in the U.S.
The ADA also cited a more recent study from the University of Queensland, which found no measurable impact on children's cognitive development or IQ at fluoride levels similar to those in the U.S. Dr. Brett Kessler, president of the ADA, reiterated that fluoridated water, along with regular brushing with fluoride toothpaste and a healthy diet, is a proven and effective way to prevent dental disease.
The ADA also pointed to concerns over the National Toxicology Program’s (NTP) monograph, which formed the basis of the JAMA Pediatrics study. The ADA highlighted flaws in the NTP’s report and referenced a District Court ruling that concluded the report did not prove fluoridated water harms public health.
While the ADA remains open to future research, it continues to support the safety and effectiveness of optimally fluoridated water for public health.
