For decades, fluoride has been held in high regard by the dental community as an important mineral that is absorbed into and strengthens tooth enamel, thereby helping to prevent the decay of tooth structures.

In nearly every U.S. community, public drinking supplies are supplemented with sodium fluoride because the practice is acknowledged as safe and effective in fighting cavities.

Some private wells may contain naturally fluoridated water.

Fluoride is absorbed into structures, such as bones and teeth, making them stronger and more resistant to fractures and decay. A process in your body called "remineralization" uses fluoride to repair damage caused by decay.

Just drinking public water will provide a certain measure of fluoride protection. But for years, health professionals have endorsed supplementing our intake with certain dietary products and topical fluorides in many kinds of toothpaste and some mouth-rinses. Certain beverages, such as tea and soda, may also contain fluoride. Dental varnishes and gels may also be applied directly to teeth to boost fluoride intake.
