The debate over Fluoridation being used in public water supplies is about as old as the practice itself.  I was raised in a DFW suburban city that used fluoridation, and at least to my knowledge, I have had no ill effects but very healthy teeth.

Was it the added fluoride,  genes or just good hygiene?  One of the first two probably played a bigger role than my personal habits.   The debate has raged on for years and I have seen good arguments on both sides.  The information below was recently forwarded to me and seems to make a good case against fluoridation:

NIH Studies link Fluoridated water to Brain Tumors, Cancers of Mouth, Pharynx, Colon, Rectum, Liver, Urinary Organs, Bones, T-cell System Hodgkin’s Disease, Non-Hodgkin Lymphoma, Multiple Myeloma, Melanoma of the Skin, Monocytic Leukemia, etc, etc… J Epidemiol. 2001 Jul;11(4):170-9.

Abstract:  Age-specific and age-standardized rates (ASR) of registered cancers for nine communities in the U.S.A. (21.8 million inhabitants, mainly white) were obtained from IARC data (1978-82, 1983-87, 1988-92). The percentage of people supplied with “optimally” fluoridated drinking water (FD) obtained from the Fluoridation Census 1985, U.S.A. were used for regression analysis of incidence rates of cancers at thirty six sites (ICD-WHO, 1957). About two-thirds of sites of the body (ICD) were associated positively with FD, but negative associations were noted for lip cancer, melanoma of the skin, and cancers of the prostate and thyroid gland. In digestive organs the stomach showed only limited and small intestine no significant link. However, cancers of the oral cavity and pharynx, colon and rectum, hepato-biliary and urinary organs were positively associated with FD. This was also the case for bone cancers in male, in line with results of rat experiments. Brain tumors and T-cell system Hodgkin’s disease, Non-Hodgkin lymphoma, multiple myeloma, melanoma of the skin and monocytic leukaemia were also correlated with FD. Of the 36 sites, 23 were positively significant (63.9%), 9 not significant (25.0%) and 4 negatively significant (11.1%). This may indicate a complexity of mechanisms of action of fluoride in the body, especially in view of the coexising positive and negative correlations with the fluoridation index. The likelihood of fluoride acting as a genetic cause of cancer requires consideration.

If you make the decision to stop adding fluoride to your municipal water supply, may I suggest that money be used for cleaning the sediment out of the bottom of your storage tanks.  I can’t think of a better way to improve water quality and  reduce treatment chemical cost with minimal expense, see: http://www.ronperrin.com.
