While at heightened risk, poor families are least able to afford avoiding fluoride once it is added to the water supply. We performed a systematic review and meta-analysis of published studies to investigate the effects of increased fluoride exposure and delayed neurobehavioral development.
Recent testing by the National Sanitation Foundation suggest that the levels of arsenic in these silicon fluorides are relatively high up to 1. Once fluoride is put in the water it is impossible to control the dose each individual receives because people drink different amounts of water.

The paper concludes that given the questionable evidence of benefit and increasing evidence of harm the policy of water fluoridation for the prevention of dental caries should be abandoned in favour of more effective interventions combining communitywide and targeted oral health interventions.
Lin Fa-Fu; et al No one can deny that high natural levels of fluoride damage health. Many scientists, doctors and dentists who have spoken out publicly on this issue have been subjected to censorship and intimidation Martin His analysis is based on a detailed review of the effect of fluorides on physiological functions and concludes that there are harmful effects from adding artificial fluoride compounds to water supplies.
Further studies by McKay, Kempf, and Churchill on water samples in areas in Idaho and Arkansas in confirmed the link between mottled enamel and high water fluoride levels [ 2 ].
