Why Is Fluoride Added To Drinking Water

Fluoride is used to fight tooth decay in children. The key initial studies purporting to demonstrate its effectiveness as an anti-cavity fighting compound were performed back in the 1940s. Those studies, conducted in Grand Rapids, MI in 1945, in Newburgh, NY in 1945, in Brantford, Ontario in 1945, and in Evanston, IL in 1947, are now being called into question. According to Dr. Philip Sutton, author of “The Greatest Fraud: Fluoridation” *A Factual Book, Lorne, Australia, 1996), these studies are actually of dubious scientific quality.

More recently, other studies attempting to document the effectiveness of fluoride have been conducted. Dr. John Yiamouyiannis examined the raw data from a large study that was conducted by the National Institute for Dental Research (NIDR). He concluded that fluoride did not appear to have any decay preventing success, as there was little difference in the DMFT values (the mean number of decayed, missing or filled teeth) for approximately 40,000 children. It did not matter whether they grew up in fluoridated, non-fluoridated or partially fluoridated communities. (Yiamouyiannis, J.A. “Water Fluoridation and Tooth Decay: Results from the 1986-87 National Survey of U.S. Schoolchildren”, Fluoride, 23, 55-67, 1990).

A larger study has been conducted in New Zealand. There, the New Zealand National Health Service plan examines the teeth of every child in key age groups, and have found that the teeth of children in non-fluoridated cities were slightly better than those in the fluoridated cities. (Colquhoun, J. “Child Dental Health Differences in New Zealand”, Community Healthy Services, XI 85-90, 1987).

Although children’s teeth have improved steadily from the 1930s to the 1990s, this improvement appears to be independent of the addition of fluoride to the water. A study has yet to be conducted that specifically addresses whether the addition of fluoride affects the quality of teeth, while controlling and accounting for other factors and other sources of fluoride.
