What it is
What is a root canal?
Inside every tooth is a soft core called the pulp, made of nerves, blood vessels and connective tissue. It runs from the chamber under the biting surface down narrow channels in each root, the root canals. When bacteria reach the pulp through deep decay, a crack or an injury, it becomes inflamed or infected. Unlike gum or skin, pulp cannot heal itself once that happens.
Root canal treatment, also called endodontic treatment, removes the damaged pulp, cleans and disinfects the canals, then fills and seals them so bacteria cannot get back in. The tooth stays in your jaw, keeps chewing normally and holds the teeth beside it in place, which is usually a better long-term result than taking it out and replacing it.
