Endodontic treatment removes infection from the inside of your tooth. Underneath the hard enamel and the dentin of your tooth is a soft tissue called the pulp. The pulp contains blood vessels, nerves, and connective tissue.
The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root. The pulp is important during a tooth’s growth and development, but once a tooth is fully mature it can stay in place without the pulp. Your teeth stay attached via the supporting ligament (or periodontal ligament).
