actually it doesn't, read a book. there is no such thing as a fluoride deficiency, it's not a mineral your body needs. drinking fluoride does nothing for your teeth, when they use it at the dentist office it's a gel, and you don't swallow it. the point is the side effects. name a single organ or bodily function that requires flouride. perhaps you're thinking of iodine?   the flouride that is in drinking water is not that mineral, it's a waste product of aluminum production. if it's naturally in air soil and water, then why is something artificial, artificially added?
