2) Fluoridation is not necessary. Most Western European countries are not fluoridated and have experienced the same decline in dental decay as the US (See data from World Health Organization in Appendix 1, and the time trends presented graphically at http://www.fluoridealert.org/who-dmft.htm ). The reasons given by countries for not fluoridating are presented in Appendix 2.)
3) Fluoridation’s role in the decline of tooth decay is in serious doubt. The largest survey ever conducted in the US (over 39,000 children from 84 communities) by the National Institute of Dental Research showed little difference in tooth decay among children in fluoridated and non-fluoridated communities (Hileman 1989). According to NIDR researchers, the study found an average difference of only 0.6 DMFS (Decayed Missing and Filled Surfaces) in the permanent teeth of children aged 5-17 residing in either fluoridated or unfluoridated areas (Brunelle and Carlos, 1990). This difference is less than one tooth surface! There are 128 tooth surfaces in a child’s mouth. This result was not shown to be statistically significant. In a review commissioned by the Ontario government, Dr. David Locker concluded:
“The magnitude of [fluoridation's] effect is not large in absolute terms, is often not statistically significant and may not be of clinical significance” (Locker 1999).
