Standard 7: Obj. 1

Outline the dental caries process

TermDefinition
1. Acids in plaque attack the tooth remove minerals in your tooth's hard, outer enamel. This erosion causes tiny openings or holes in the enamel — the first stage of cavities. Once areas of enamel are worn away, the bacteria and acid can reach the next layer of your teeth, called dentin.
2. Calcium and phosphate are dissolved from the enamel (demineralization) may be either precipitated together somewhere else in the tooth or lost to the mouth via the plaque and saliva.
3. Fluoride, calcium, and phosphate are re-deposited into the tooth (remineralization) natural repair process for non-cavitated tooth lesions, in which --ions are deposited into crystal voids in demineralised enamel. -- can contribute towards restoring strength and function within tooth structure.
4. Acids in saliva attack the tooth does not have enough capacity to aid in neutralization. The teeth are subjected to tooth erosion, increased tooth wear and in the presence of bacteria tooth decay.
