 Tooth decay, trauma or cracks can cause the nerves of teeth to die. When this occurs your tooth can often still be saved with root canal therapy. Severe pain, swelling, sensitivity to hot or cold, or a darkening tooth, are signs that a root canal problem exists. Dentists must use x-rays to confirm proper treatment. Your root canal can be done under sedation if you are apprehensive about the procedure, or you have been uncomfortable at the dentist in the past. During root canal treatment, the dentist cleans out the infected nerve area within the roots. After all the nerve has been removed, the canals are sealed to prevent a future root canal infection. In most cases, your root canal procedure can be finished in one visit. After a root canal, most patients experience little pain. All patients are given pain relievers however, to minimize any discomfort. Teeth treated with root canal need to be restored afterwards. This could range from a simple filling to a large build-up with a post. If much tooth structure is missing, the tooth may require a crown to protect the tooth from further damage.
