Root Canal

The root canal is the hollow space inside the root of a tooth that in a healthy state is occupied by the dental pulp.  The dental pulp consists of nerves that provide sensation inside the tooth, blood vessels which supply oxygen and nutrients to the tooth and connective tissue.  If a tooth is decayed or fractured deeply enough that it causes pain, it is the nerves of the dental pulp that convey that message to the brain.

When the contents of the root canal system deteriorate due to trauma or bacterial attack, the resulting abscess can necessitate endodontic treatment, also called root canal therapy.
