Pro-fluoridationists claim that the reduction of tooth decay since the 1950’s is a result of fluoridation. However tooth decay has been declining since the 1920’s, long before fluoridation was introduced and has continued to decline at the same time rate in fluoridated and non-fluoridated areas, showing that fluoridation has no effect upon tooth decay.
Part 3: Fluoridation’s effectiveness is a myth. In the first two parts of this series, I discussed the history and disastrous health impacts of water fluoridation and suggested safer and more effective alternatives. In this final part I explain why the more than 100 studies pro-fluoridationists cite in favour of fluoridation are invalid and contradicted by abundant evidence that water fluoridation does not benefit teeth at all. More research issues are uncovered in the main article.
