Root Canal Treatment, also known as Endodontics Treatment, is a dental procedure in which the diseased or damaged pulp (core) of a tooth is removed, and the inside areas (the pulp chamber and root canals) are filled and sealed.
Endodontics / Root canal treatment is a specialty of dentistry that deals with diseases of the dental pulp and its supporting structures. In order to understand Endodontics treatment, Teeth have several layers. The outside layer of the tooth is composed of a hard layer called enamel. Enamel is supported by an inner layer called dentin, which has at its center a soft tissue known as the pulp.
The pulp receives its nourishment supply from vessels which enter the end of the root. Although the pulp is important during development of the tooth, it is not necessary for function of the tooth. The tooth continues to be nourished by the tissues surrounding it even after the pulp is removed.
