The consumption of sugar and other carbohydrate-containing foods, the bacteria in our mouth cause acid formation. In the presence of the acid plaque, bacteria can accumulate on the enamel surface as the cleaning effect of saliva declines. If this acid level drops below the critical pH, it will cause the enamel to dissolve.
As mineral dissolution continues, cavities occur on the tooth surface. Balancing the acid in a healthy and balanced flora can be achieved by saliva. When holes appear on the tooth surface, irreversible damage to the tooth enamel occurs.
