  • Yes, high concentrations of anything aren’t good for you. That study found a negative effect at comparatively high levels, but did not quantify any safe level, let alone conclude the safe level is zero.

    Our review cannot be used to derive an exposure limit, because the actual exposures of the individual children are not known. Misclassification of children in both high- and low-exposure groups may have occurred if the children were drinking water from other sources (e.g., at school or in the field).

    Based on known performance in areas with lower fluoridation (≤1 mg/L), it would suggest there is a safe limit that can improve dental health without neurotoxicity.
