Root Canal Treatment

First of all we should know about the basic structure of the tooth. The part which we can see in the oral cavity is called crown. And the part if the tooth which is embedded in the bone is called root of the tooth. Now the tooth has inner core called pulp which comprises blood vessels, nerve tissues, etc. this pulp is present in the crown portion of the tooth which is called as pulp chamber. This pulp chamber extends in to the root and takes the shape of root which is called root canal.

Now as shown in the figure decay start in the crown portion of the tooth, which if left untreated progresses to involve the pulp of the tooth. This causes infection of the root canal system.

Procedure: first of all, decayed portion is removed and pulp chamber of tooth is opened. local anesthesia is given if required. Then with special instrument pulp tissue is removed and after that filling is done in the root canal of the tooth.

When the root of a tooth becomes infected, a root canal will be necessary to save the tooth. The only alternative to a root canal is extraction of the tooth.

The symptoms of an infected tooth are:

  • Sensitivity to hot or cold foods and liquids.
  • Swelling and pain
  • Persistent bad taste in the mouth

Sometimes an infected tooth won't even hurt. But, if left untreated it could develop into a serious medical emergency.
