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 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 a compound of the element fluorine, which can found throughout nature in water, soil, air and food. By adding fluoride into our drinking water, it can be absorbed easily into tooth enamel, especially in children’s growing teeth, which helps to reduce tooth decay.
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 the practice of supplementing our intake with certain dietary products, and topical fluorides in many toothpastes and some kinds of rinses. Certain beverages such as tea and soda may also contain fluoride. Certain kinds of dental varnishes and gels may also be applied directly to teeth to boost fluoride intake.
