Fluoride good for older teeth too

If you're a fan of your local water supply, the added fluoride used to help prevent tooth decay in kids may in fact be just as good for teeth in older adults, according to a new study.

The study revealed that fluoride levels in ordinary tap water may be preventing tooth decay in American adults as well. The only problem is that many municipalities use fluorosilic acid instead of fluoride.

Want to know where it comes from? I suggest you obtain that information from your local water authority. In fact, demand that information, then make your decision on whether tap water -- fortified or not -- is the best choice (adult or child).
