Dental cavities or caries is one of the most common of all disorder. It is an infection caused by a combination of carbohydrate-containing foods and bacteria that live in our mouth. When these bacteria find carbohydrates, they consume them to produce acids. The acids demineralize the hard part of the tooth; enamel and dentine and eventually, reach the pulp chamber. The bacteria are contained in a film called plaque. Plaque begins to accumulate on the teeth within 20 minutes after eating. If the plaque is not removed thoroughly and routinely, tooth decay will occur. Treatment of a cavity generally consists of two steps; removing the decayed portion of the tooth and under a local anesthesia, a high speed dental drill is used to remove the decay and prepare the tooth for the filling, rebuilding the missing tooth structure with a suitable filling material.
