Root canal treatment, despite all of the misleading myths and misconceptionsspread about it, does, in fact, provide an invaluable service. It allows a means by which severely damaged teeth can be saved.
So to help you understand how this is possible, our pages outline the individual steps of having root canal (endodontic therapy) and explain itstreatment goals.
Our pages also discuss issues such as why a dental post and crown may be needed after treatment, why therapy sometimes fails, treatment costs, and whether this or a dental implant makes the better choice.

Root canal therapy refers to the process where a dentist treats the interior aspects of a tooth, specifically, that space occupied by its "pulp tissue." Most people would probably refer to a tooth's pulp tissue as its "nerve," however, doing so is only partially accurate. While pulp tissue does contain nerve fibers, it is also composed of arteries, veins, lymph vessels, and connective tissue. On our pages, so to use terminology that people seem to be most familiar with, we have chosen to use the terms nerve, nerve tissue, and pulp tissue as if they all refer to the same thing.

Where precisely in a tooth is its nerve?
Teeth are not solid objects. Inside every tooth there lies a hollow space that contains its nerve tissue. Dentists use the following terms to refer to various portions of this nerve space:

A) The pulp chamber.
This is the hollow area that lies, more or less, in the center of the tooth's crown (that part of the tooth positioned above its gum line).

B) The root canals.
A tooth's root canals run from the apex (tip) of its root up to its pulp chamber.
The layout of the nerve space inside different types of teeth is quite different. Teeth always have just one pulp chamber but the number of individual root canals that they have can vary widely. Every tooth will have at least one root, and some have 2, 3 or possibly more. Each tooth root will have at least one root canal. The roots of some teeth, however, are well known for frequently having 2 or more canals. (Really, this variation is possible with pretty much any root.)
