The pulp inside a tooth can become inflamed or infected after deep decay, a fracture or an injury. You may notice lingering sensitivity, night pain or swelling of the gum.
Root canal treatment aims to clean that tissue and, where possible, keep the tooth. Pain does not automatically mean a root canal is needed; the decision follows examination and, if useful, an X-ray.
The procedure is usually done with local anaesthetic. The number of visits depends on the tooth. A filling or crown is part of completing the care.
Only an examination can lead to a diagnosis. This article is not a substitute for one.
Information on this page is for general guidance. The right treatment for you is decided by your dentist after examination and any necessary tests.
