There are a number of reasons you may need a root canal near Bel Air . A root canal is a procedure performed by a dentist to remove the tooth nerve. The procedure is done to save a tooth that has become infected or shows signs of bad decay. It may not always be immediately apparent when a root canal is necessary. This article will highlight some of the more common reasons a root canal would be required.
When Tooth Pain is Present
Not all tooth pain is a reason to have a root canal, but pain is a major indicator that something is wrong. If the pain is 
present when eating or when pressure is applied, it could be indicative of nerve damage. Extra sensitivity or pain to hot and cold is also a sign of nerve damage. If a tooth that is infected or badly decayed causes the pain, a root canal will need to be performed to stop the pain.
If a Tooth has Become Abscessed
If a tooth that is infected is left untreated, an abscess will form. An abscess is a pocket of puss that forms in the tooth. An abscessed tooth can spread to other teeth and gums, furthering the infection. While it may or may not cause pain, an abscessed tooth is usually visually noticeable. The puss pocket that forms has an appearance similar to that of a pimple. Some patients with an abscessed tooth may even notice puss oozing from the affected area. A root canal is necessary to repair the abscessed tooth.
When a Tooth has Been Damaged
Any time a tooth is damaged and the nerve is affected, a dentist will likely perform a root canal. In the event of trauma to the tooth, such as being hit in the face with enough force to damage a tooth, the nerve can be severed. If this happens, a root canal can be performed to fix the nerve.
