fluoridation

 [floor″-ĭ-da´shun]
treatment with fluorides; the addition of fluorides to community drinking water as a measure to reduce the incidence of dental caries. Minute traces of fluoride are found in almost all food, but the quantity apparently is too small to meet the requirements of the body in building tooth enamel that resists cavities. Drinking water containing one part fluoride to one million parts of water does meet this need and has been found to reduce tooth decay in children by as much as 40 per cent. Since few natural water supplies contain the necessary amount of fluoride, it usually must be added if protection against tooth decay is desired. Statistics indicate that 20 per cent of the teenagers who drank fluoridated water from birth have teeth totally free of caries. The practice of fluoridating water is rated among the most cost-effective preventive programs in public health.

There also is evidence that topically applied fluoride solutions help alleviate periodontal disease by removing bacteria from the site and rebuilding supporting bone tissue around the teeth. Dental professionals may apply fluoride solutions directly to a child's teeth, beginning at age 5 or 6 and repeating the treatment each year throughout life. This has been found to reduce caries by about 40 per cent.

The dentist or other health care provider may prescribe chewable fluoride tablets if fluoride is not available in drinking water. However, use of these tablets must be carefully supervised, since an excess of fluoride causes dental fluorosis. Like most medicines, fluoride in large amounts is a poison. A dentifrice containing fluoride, or fluoride in gel form, may also prove effective. A dentist or dental hygienist should be consulted before any fluoride preparation is used.

fluor·i·da·tion

(flōr'i-dā'shŭn),
Addition of fluorides to a community water supply, usually about 1 ppm, to reduce incidence of dental decay.

fluoridation

The addition of small amounts of fluoride to drinking water to reduce the incidence of cavities.
 
Fringe medicine
It is widely believed by those interested in alternative health that the addition of fluoride to the drinking water causes AIDS, Alzheimer’s disease, birth defects, cancer and a wide range of other conditions.
 
Public health
While most data suggest that fluoridation may reduce the incidence of caries, it is unclear whether fluoride actually has this effect; soft data suggest possible carcinogenesis. More than 1/2 of the US water supply has > 0.7 ppm of fluoride, a level that is considered adequate to reduce the incidence of caries.

fluor·i·da·tion

(flōr'i-dā'shŭn)
Addition of fluorides to a community water supply, usually 1 ppm or less, to reduce incidence of dental decay.

fluoridation

Deliberate addition of fluorine compounds to drinking water supplies in areas in which the water is low in fluoride. The presence of about one part of fluoride per million parts of water promotes stronger and healthier teeth with reduced tendency to tooth decay. Fluoridation is a valuable public health measure.

fluoridation

the addition of a fluoride, usually sodium fluoride, to drinking water in a concentration of about 1 ppm, in order to reduce the decay of teeth. Teeth may also be treated directly with a fluoride gel by the dentist, and this is usually undertaken as a treatment for children.

fluor·i·da·tion

(flōr'i-dā'shŭn)
Addition of fluorides to a community water supply, usually about 1 ppm, to reduce incidence of dental decay.
