Fluoride Facts
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. The CDC Web site provides information on community water fluoridation. People seeking information on whether their water system is fluoridated, can now find out by visiting a new Web site at the Centers for Disease Control and Prevention (CDC).
What Is Fluoride?
Fluoride is a natural mineral found in the water we drink and in many kinds of foods. Teeth benefit both topically and systemically from fluoride.
Why Is Fluoride Important To Teeth?
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.
How Do I Get Fluoride?
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.
Fluoride Safety
It is generally NOT safe to swallow toothpastes, rinses, or other products containing topical fluoride. In rare cases, some people may be overexposed to high concentrations of fluoride, resulting in a relatively harmless condition called fluorosis, which leaves dark enamel stains on teeth.
