Tooth decay occurs as teeth are frequently exposed to foods containing carbohydrates (starches and sugars) like chocolates, sweets, ice creams, cakes, and even fruits, vegetables and juices. Oral cavity contains numerous bacteria and these bacteria forms plaque. The plaque interacts with deposits of food left on teeth from sugars and starch to produce acids. These acids in turn damage the tooth enamel over a period of time by demineralizing the structure of teeth, resulting in tooth decay and weakened teeth.
