Tooth decay; progressive decalcification of the enamel and dentin of a tooth. The condition is caused by dental infection, and the erosion of teeth by the acid byproducts of bacterial metabolism on their surfaces.

PREVENTION
Minimizing the dietary intake of refined sugars and careful toothbrushing twice a day with a fluoride-containing toothpaste reduces the incidence of dental caries. Use of dental floss or tape removes plaque from between adjacent tooth surfaces; deep pits and fissures may be sealed by the application of resins. The sealant may need to be replaced periodically. Early detection and dental restorations offer the best form of control once caries has formed. Topical application of fluoride promotes resistance to dental caries. Dental caries is less likely to develop if appropriate amounts of fluoride are ingested while the teeth are developing. It is important that excess fluoride not be ingested because greater amounts than required (about 1 mg/day) cause mottling of the teeth. Fluoride in the diet does not obviate the need for topical application of fluoride to the teeth.
