Not to open a can of worms, however in my opinion, the research that I have read on fluoride in the drinking water is related to many health problems and studies show it does not have an effect on tooth decay. The dental community has been brainwashed starting in dental school by the pharmaceutical industry. It's all about the money and profits like most drugs rather than the health of the patient. Please see the following links for a view into this topic that you may not have heard and will open your eyes. Watch the following videos with an open mind.
The ADA and pharmaceutical companies are not our friends - follow the money.
The Fluoride Deception is the latest mini documentary from Mike Adams, executive director of the Consumer Wellness Center. Through the use of animation and motion graphics, it exposes the truth about where fluoride really comes from: The toxic byproducts of the phosphate mining industry.

The Politics of Fluoride “[T]he political profluoridation stance has evolved into a dogmatic, authoritarian, essentially antiscientific posture, one that discourages open debate of scientific issues.”
– Dr. Edward Groth, Senior Scientist, Consumers Union, 1991. F.A.N.tv is home to an evolving catalogue of both full length documentaries and short clips. The videos, which feature FAN's interviews with leading figures in fluoride research, including dentists, toxicologists, and award-winning journalists, seek to shed light on the health concerns with current fluoride exposures and the history/politics of the water fluoridation program.
