This chart is based upon the data collected in the largest dental survey carried out in the US (NIDR, 1986-87). The study examined tooth decay and dental fluorosis among 39,000 children in 84 communities. The blue bars show that as community fluoride water levels went up so does the prevalence of dental fluorosis. This is a STRONG relationship. In contrast, as the community fluoride water levels go up there is very little - if any - significant difference in tooth decay (striped pink bars). This is a VERY WEAK relationship.
What kind of risk would you impose on the developing brains of babies and young children to achieve this questionable benefit?
See the petition to the USA EPA to ban fluoridation under the Toxic Substance Control Act (TSCA).
