Root Canal Treatment (RCT) is the dental treatment required to save a tooth. When decay (caries) goes beyond the 2 layers of the tooth, Enamel and Dentine, it reaches the innermost chamber of the tooth- PULP CHAMBER. The pulp chamber contains the blood vessels, nerve tissue and lymphatic tissue.
When the pulp chamber of the tooth is exposed, the tooth can not be filled by normal fillings. The pulp chamber and the root canal needs to be cleaned and filled in till the apex of the root.
