What is Root Canal?

• A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.
• "Root canal" is the term used to describe the natural cavity within the center of the tooth. The pulp or pulp chamber is the soft area within the root canal. The tooth's nerve lies within the root canal.
• A tooth's nerve is not vitally important to a tooth's health and function after the tooth has emerged through the gums. Its only function is sensory -- to provide the sensation of hot or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth.

Root canal treatment Steps:

• First, an opening is made through the back of a front tooth or the crown of a molar or pre-molar.
• After the diseased pulp is removed (a pulpectomy), the pulp chamber and root canals are cleaned, enlarged and shaped in preparation for being filled.
• If more than one visit is needed, a temporary filling is placed in the crown opening to protect the tooth between dental visits.
• The temporary filling is removed and the pulp chamber and root canal permanently filled. A tapered, rubbery material called gutta-percha is inserted into each of the canals and is often sealed into place with cement. Sometimes a metal or plastic rod is placed in the canal for structural support.
• In the final step, a crown is usually placed over the tooth to restore its natural shape and appearance. If the tooth is very broken down, a post may be required to build it up prior to placing a crown.
