Root canal treatment (also referred to as root canal therapy or endodontic therapy) can become necessary when a tooth has is history of large cavities, multiple restorations, or trauma. These things can damage the nerve inside the tooth beyond the body’s ability to heal itself. During a root canal the infected pulpal tissues are removed, the area disinfected, and the area filled. In most cases after root canal treatment a tooth will need a full coverage crown to restore and strengthen it.
