The therapy, also called endodontic therapy, is a series of treatments performed on infected nerves in the tooth pulp. A root canal is a capillary that extends from the bottom of the root to the midpoint of the crown. This tubular structure contains the pulp, which gives life to the tooth. Severe tooth ache (requiring the therapy) happens when the nerve of the tooth is damaged. This damage can happen due to cavity that makes deeper recesses into the tooth and touches nerves in the pulp. On the touching the nerve, the bacteria-filled cavity causes the root canal to swell up, which in turn causes pain.
Every tooth in your mouth has anywhere from 1 to 4 root canals. These are tiny passageways that run from the top of your tooth to the end of the root in your jaw. These root canals connect to the nerve tissue, or pulp, in the center of your tooth, which supplies vital nutrients to your teeth. Symptoms of damaged or infected nerve tissue in your tooth include pain, persistent sensitivity to hot or cold, pain while chewing, tender to the touch, swelling, and draining. Through simple tests and x-rays, your dentist can tell if you have a damaged tooth that requires a root canal.
The treatment for root canal takes only about two visits to the dentist. First is the procedure to remove the pulp. The next is the capping or replacement of the tooth for a permanent crown. It is perfectly safe for a pregnant woman to undergo this kind of treatment if necessary. The X-rays on the mouth only entail minimal exposure and they are far from the abdomen. Oral healthcare has improved today as dentists are implementing superior medical techniques to cure dental problems. Implementation of these techniques is resulting in several successful dental surgeries which are evident from the records of dental cases in America for the year 2009.
