A report from the National Research Council concluded that adverse effects of high fluoride concentrations in drinking water may be of concern.

Fluoride may cause neurotoxicity in laboratory animals, including effects on learning and memory.

Children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.

Fourteen recent cross-sectional studies from endemic areas with naturally high fluoride concentrations in groundwater supported the previous findings of cognitive deficits in children with elevated fluoride exposures.

A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations.
