write chemical equation for tooth decay

HÈRÈ Ïẞ ÃÑẞWÈR TØ YØÜR QÜÈẞTÏÔÑ:
The acids that cause tooth demineralization (cavity formation) are produced by specific types of bacteria (mutans streptococci and lactobacilli) that live in dental plaque.
These bacteria are living organisms just like we are. When we consume foods and beverages, we create waste products. Bacteria do the same thing. The bacteria that cause tooth decay utilize sugars (glucose, sucrose, fructose, lactose, or cooked starches) as their food source. The waste products created from digesting these sugars are the acids (especially lactic acid) that cause the demineralization of tooth enamel and dentine.
Since the bacteria that live in our mouth eat when we do, as we ingest foods which contain sugars (such as soda, candy, milk, and even fruits and vegetables) these bacteria get a meal too. And within minutes they start producing the acids that cause tooth decay.
Chemical equation would be
CH3CH(OH)COOH + CaCO3(from enamel of tooth) ........>[CH3CH(OH)COO]2Ca + CO2+ H2O
The acid produced dissolves the calcium from enamel of teeth causing decay.
Answer:
pH and Tooth Decay. Teeth are made up of a soft material called dentin covered by a hard enamel layer. The outer layer is mostly hydroxyapatite (Ca10(PO4)6(OH)2), a sparingly soluble salt. Tooth decay occurs when the teeth become demineralized (or the hydroxyapatite dissolves) and cavities form.
