Since 1945, municipal systems serving 170 million Americans have added fluoride (mostly in the form of hydrofluorosilicic acid) to their water, and the prevalence of cavities in the U.S. has fallen dramatically.

Fraunhofer and dental student Matthew Rogers took 20 healthy teeth extracted for orthodontic or periodontal reasons, cut them into tiny blocks of tooth enamel and exposed the blocks to a variety of popular soft drinks, including Coke, Pepsi, Mountain Dew, Dr Pepper, Sprite, Canada Dry ginger ale and canned Arizona iced tea. All the drinks weakened or permanently destroyed the enamel. Diet sodas were just as bad as regular sodas, and canned iced tea caused...
