Fluoridated drinking water does not help prevent tooth decay. "Dental fluorosis -- a condition in which your tooth enamel becomes progressively discolored and mottled -- is one of the first signs of over-exposure to fluoride. Eventually, it can result in badly damaged teeth and worse... It's important to realize that dental fluorosis is not "just cosmetic" as the EPA and the US Centers for Disease Control and Prevention (CDC) suggest. Dental fluorosis can also be an indication that the rest of your body, such as your bones and internal organs, including your brain, has been overexposed to fluoride as well. In other words, if fluoride is having a visually detrimental effect on the surface of your teeth, you can be virtually guaranteed that it's also damaging other parts of your body, such as your bones." http://articles.mercola.com/sites/articles/archive/2013/12/24/fluoride-toxicity.aspx Nothing on this site should be trusted until their data reflects data updated by recent research.
