What Is Root Canal Treatment?

The root canal is the hollow section of the tooth containing nerve tissue, blood vessels, and pulp. A tooth consists of crown, which is above the gum line and the roots that are below the gum line. The roots attach the tooth to the jawbone. Inside the crown and roots, there is pulp, which nourishes the tooth.

The dentist then cleans, shapes, and sanitizes the hollow area by using tiny files. The tooth is then filled with rubber-like material using an adhesive cement to seal the canals.
