Of the 19 high-quality studies assessing the association between fluoride and IQ in children, 18 reported an association between higher fluoride exposure and lower IQ in children. Forty-six of the 53 low-quality studies also found evidence of that association.

This review finds, with moderate confidence, that higher fluoride exposure (e.g., represented by populations whose total fluoride exposure approximates or exceeds the World Health Organization Guidelines for Drinking-water Quality of 1.5 mg/L of fluoride) is consistently associated with lower IQ in children.
