Abstract
The debate surrounding fluoride use for caries control has intensified due to recent events, including a National Toxicology Program (NTP) report and a court ruling mandating EPA action on fluoride levels in tap water.
Despite concerns about fluoride's potential neurodevelopmental impact at high concentrations, current evidence shows no adverse effects at the recommended levels of 0.7 ppm in U.S. community water fluoridation programs. While studies in regions with endemic fluorosis suggest an association between high fluoride exposure and lower IQ, methodological limitations undermine causal conclusions.
Global and U.S. health authorities, including the WHO and ADA, reaffirm the safety and efficacy of fluoride as a cornerstone of public health strategies against dental caries. Continued research is essential, but current recommendations remain robustly supported.
