fluoride: Higher fluoride exposure, especially drinking water above about 1.5

Higher fluoride exposure, especially drinking water above about 1.5 mg/L, is associated with lower IQ in children in major reviews, but this should not be flattened into an identical claim about every lower-dose fluoridation system.

fluoride: Current evidence is insufficient to determine whether the U.S.

Current evidence is insufficient to determine whether the U.S. recommended community water fluoridation level of about 0.7 mg/L negatively affects child IQ.

Expert context2 sources

fluoride: Broad claims that community water fluoridation is a major

Broad claims that community water fluoridation is a major cancer driver are weaker and less central than the better-supported debates around dental caries, fluorosis, total exposure, and child neurodevelopment at higher exposure.
