With successful root canal treatment, the tooth will no longer cause pain. However, because it does not contain an internal nerve, it no longer has sensitivity to hot, cold, or sweets. Because these are signs of dental decay, the root canal recipient...
must receive regular dental check-ups with periodic x rays to avoid further disease in the tooth. The restored tooth may last a lifetime. However, with routine wear, the filling or crown may eventually need to be replaced.

This narrated animation shows how root canal surgery can save a natural tooth from destruction from advanced tooth decay. A cut away view of the tooth is shown along with the steps required to replace the diseased core of the tooth. In this version of a root canal, an artifical crown is placed, commonly referred to as a dental cap.
During a root canal, the diseased pulp of a tooth (A), is removed (B). The remaining empty tooth is filled and sealed with a filling or crown. (Illustration by GGS Inc.)

Other Information
In the situation that a tooth is considered so threatened (because of decay, cracking, etc.) that future infection is considered likely or inevitable, a pulpectomy, removal of the pulp tissue, is advisable to prevent such infection. Usually, some inflammation and/or infection is already present within or below the tooth. To cure the infection and save the tooth, the dentist drills into the pulp chamber and removes the infected pulp by scraping it out of the root canals. Once this is done, the dentist fills the cavity with an inert material and seals up the opening. This procedure is known as root canal therapy. If enough of the tooth has been damaged, or removed as a result of the treatment, a crown may be required.
