Tooth decay is the result of an infection with certain types of bacteria that use sugars in food to make acids. Over time, these acids can make a cavity in the tooth.
Our oral cavity consists of millions of bacteria living on our teeth, gums, tongue and oral mucosa. Some of these bacteria are helpful in digestion whereas others play essential role in the tooth decay process.
When a tooth is exposed to foods or drinks containing sugar and starch and any part of it stays in the mouth for a longer period of time, it causes acid attacks which in turn makes the enamel loose it’s vital minerals. A white spot appears where minerals have been lost and this is the first sign of decay.
Tooth decay process can be stopped or reversed at this point. Enamel can repair itself by using minerals from saliva, and fluoride from toothpaste or other natural sources. But if the tooth decay process continues, more minerals are lost from the tooth. Over time, the enamel and dentin are destroyed, resulting in a tooth cavity. A tooth cavity is permanent damage to the tooth structure that has to be repaired with a filling or a restoration.
