How are dental caries formed?

Answer 1

caries caries Dental caries is a bacterial disease that begins with demineralization of the outermost dental enamel and progresses, if not halted, to loss of tooth substance and infection of the dental pulp. Demineralization begins with acid formation in dental plaque, the acid being a by-product of the metabolism of simple carbohydrates (sugars, cooked starches) by certain plaque-resident bacteria, principally the mutans streptococci. If demineralization is not checked, it leads to tissue loss and further bacterial penetration. The carious process is reversible in the early demineralization stage: Fluoride and other minerals in plaque can buffer the acid and lead to remineralization of the early lesion. Prevention of dental caries, therefore, is based on promoting an intra-oral environment in which demineralized enamel can quickly be remineralized, and where plaque pH does not remain below neutral for prolonged periods.

Sugars in the mouth promote bacterial growth and acid production; http://www.answers.com/topic/sucrose specifically promotes http://www.answers.com/topic/plaque-forming bacteria, which cause the most damage. A moderately high intake of http://www.answers.com/topic/fluoride increases the resistance of tooth enamel to acid attack.
