Tooth decay definition

Definition of tooth decay

Tooth decay (cavities) is caused by the acids of the mouth that are attacking the tooth which leads to decalcification and breakdown of the different structures of the tooth, starting with the enamel. Right from the outset, the dentist will detect this decalcification with the help of a dental explorer (also called a sickle probe) and by observing discoloration and brittleness of the tooth. This diagnosis is possible if the tooth decay is located on a visible part of the crown area of the tooth.
