How can I be exposed to fluoride?
Individuals can be exposed to fluoride through a wide variety of foods, drinks, and dental care products. Some foods, such as tea and seafood, have high levels of fluoride. Bottled water or beverages can contain fluoride from public water. Mineral water may also have high levels. In the case of natural waters, the variation in the fluoride content from region to region is dependent upon such factors as the source of water, type of geological formation and the amount of rainfall. (Dry regions tend to have higher fluoride.) Surface waters generally have low fluoride while ground waters typically contain more. Certain dental care products have fluoride added, and your dentist can advise you on which formulation may be beneficial to you or your child.
