Root canals (endodontics) are the primary treatment method for infections of the nerve tissue (pulp) inside a tooth. Advances in the technology and procedures associated with root canal therapy have made the success rate of root canals done today, about 95% successful.

Years ago infected teeth were routinely extracted, but now general dentists and endodontists (root canal specialist) make every reasonable effort to save these infected teeth instead of pulling them.

The most common symptoms a person would notice in a tooth needing a root canal would be pain to heat, cold and pressure, and swelling of the gums or face around the area of the tooth.

• Trauma a physical blow to the tooth or an irregular bite against an opposing tooth.

• Physical Irritation can be caused by deep decay (bacteria) microscopically invading the nerve tissue, or the drilling involved in removing this decay and placing a filling or a crown or cap on the tooth.

• Severe gum disease this factor is the leading cause of extraction of teeth among adults in the U.S. and root canals will not cure gum disease problems by themselves.
