Dental  Caries

or cavities, are very general. They start with the acid on the tooth. Acid is produced by bacteria in plaque. Plaque bacteria feed on sugars and starches from the diet and changes in acid. This acid eats into the tooth enamel, and the outer layer of the tooth and the dentin, the major area and the core of the tooth. Tooth gradually dissolves and the bacteria move into the damaged tooth structure.

It is a bacterial disease processes, damage to the hard dental tissue (enamel, dentin and cementum.These tissues gradually degraded, making a dental cavities (holes in teeth). Tooth decay occurs when foods with carbohydrates (sugars and starches) such as bread, cereals, milk, soft drinks, fruit, pastries, cookies, or left to the teeth. Bacteria that live in the mouth digest these foods, turning them into acids. bacteria, acids, residues food, saliva, forming plaque that clings to teeth. acids in plaque dissolve the enamel surface of teeth and create holes in the teeth called cavities or tooth decay.

What are the types of bacteria that cause tooth cavity

Two groups of bacteria are responsible for the initiation of caries: Streptococcus mutans and Lactobacilli
