Examining the scientific and historical landscape of water fluoridation, weighing its established dental health benefits against emerging concerns regarding neurodevelopmental risks. Documents from the National Toxicology Program (NTP) and recent meta-analyses suggest a moderate link between high fluoride exposure and lower IQ scores in children, particularly at levels exceeding 1.5 mg/L.

Experts remain divided on the implications for the current U.S. recommendation of 0.7 mg/L, as data remains insufficient to confirm risks at such low concentrations. Ultimately, this highlights an ongoing debate between major medical org ...
