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.
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, a patient could experience little discomfort from the work that was done inside the tooth. In most cases, a pain reliever will minimize any discomfort.
Teeth treated with root canal therapy need to be restored afterwards. In most cases, it is restored with a build-up, post and core and a crown over the tooth to protect it from further damage.
