cavities-in-preschoolers-300x180Dental decay is a bacterially based disease that progresses when acid produced by bacterial action on dietary fermentable carbohydrates diffuse into the tooth and demineralizes the carbonated hydrocyapatite mineral.

Pathological factors, including acidogenic bacteria, salivary dysfunction, and dietary carbohydrates are related to decay progression.

Protective factors, which include antibacterials, salivary calcium, phosphate and proteins, salivary flow, and fluorides in saliva can balance, prevent, or reverse dental decay.
