1. There is no credible evidence that fluoridated water has ever prevented a single dental cavity. Here’s some quotes from the 2015 Cochrane review of artificial water fluoridation.
    p 2 “A total of 155 studies met the inclusion criteria; 107 studies provided sufficient data for quantitative synthesis.”
    p 2 “There is insufficient information to determine whether initiation of a water fluoridation programme results in a change in disparities in caries across socioeconomic status (SES) levels.
    There is insufficient information to determine the effect of stopping water fluoridation programmes on caries levels.
    No studies that aimed to determine the effectiveness of water fluoridation for preventing caries in adults met the review’s inclusion criteria.”
    p 3 “Researchers from the Cochrane Oral Health Group reviewed the evidence – up to 19 February 2015 – for the effect of water fluoridation. They identified 155 studies in which children receiving fluoridated water (either natural or artificial) were compared with those receiving water with very low or no fluoride. Twenty studies examined tooth decay, most of which (71%) were conducted prior to 1975. A further 135 studies examined dental fluorosis.”
    p 14 “Five studies were funded by research grants from research organisations, health authorities and government organisations, one study was funded in collaboration with members of the committee pro-fluoridation, while the other studies [on caries] did not state their funding sources.”
    p 17 “We judged that all the 20 studies included for the caries outcome (including disparities in caries) were at high risk of bias overall.”
    p 17 “We found all studies to be at high risk of bias for confounding. We considered confounding factors for this outcome to be sugar consumption/dietary habits, SES, ethnicity and the use of other fluoride sources.”
    p 28 “Whilst these [fluoridated] areas tend to have low to very low DMFT, there are many other parts of the world where fluoridated water is not widespread that also have low caries levels. Equally, there are areas with relatively high distribution of water fluoridation and moderate caries levels (e.g. Brazil).”
    p 30 “The quality of the evidence, when GRADE criteria are applied, is judged to be low.”

  2. Ah Dan… Beyond the tirade of abuse on most other web sites, you may even be a nice person. And you may even be the Galileo of the modern era. Or you might just be wrong, wrong, wrong. And every reputable health and scientific authority in Australia thinks you are. All great scientists are mavericks, but sadly not all mavericks are great scientists. But if it makes you feel better, keep fighting the fight. Hope that skeletal fluorosis clears up soon.
