A new report linking fluoridated drinking water to lower IQ scores in children is sure to ratchet up the debate over a practice that's considered one of the greatest public health achievements of the 20th century.

An analysis of more than 70 studies on fluoride and IQ levels concluded there was a relationship between higher levels of the common water additive and lower IQ levels in children, though a large

(CNN) – Being exposed to high levels of fluoride could impact intelligence. According to a new government survey, fluoride levels in children’s urine were measured. They reported a drop in IQ scores as fluoride levels rose. The study was published in the medical journal JAMA Pediatrics Monday, but the research was released in late 2024.

A review of 74 medical studies links higher fluoride exposure to lower IQ in kids — but mostly draws on research that took place outside of the U.S. and had a high risk of biased results.
