A root canal actually refers to the cavity within the root of the tooth that holds the “pulp,” which is home to the blood vessels and connective tissue of the tooth’s root.
Prevent Further Tooth Decay
Root canal therapy is necessary when the nerve tissue inside the tooth, the pulp, becomes infected. An infected root canal can cause the tooth to rot from the inside out, which is extremely painful. Root canal therapy is often no more painful than a normal filling, and much less painful than the alternative tooth removal.< Back To Glossary
