Flouride in water lowers risk of cavities

The theory behind the introduction of fluoride in your water supply initially seems beneficial – to reduce the incidence of dental caries in children. However, the health dangers of fluoride are so numerous; they far outweigh any benefit to your teeth, and that's IF water fluoridation actually did what its claimed to do. Today, even promoters of fluoridation concede that the major benefits are only from topical applications; fluoride works from the outside of the tooth, not from inside of your body, so why swallow it?Statistics tell us that water fluoridation is ineffective for preventing caries. There is practically no difference in tooth decay between fluoridated and non-fluoridated countries, and no difference between states that have a high- or low percentage of their water fluoridated. Meanwhile, fluoride can cause significant harm, from dental fluorosis to thyroid damage to reduced IQ... and much more.
