Root Canal Treatment: What Patients Should Know

Root canal treatment may be recommended when the pulp inside a tooth becomes inflamed or infected. The aim is to remove the affected tissue, clean and shape the root canals, and seal the space so the natural tooth can be retained when appropriate.

Symptoms such as persistent toothache, pain when biting, swelling or prolonged sensitivity can have several causes, so an examination and often dental imaging are needed before treatment is planned.

The exact procedure, number of visits and restoration needed afterward depend on the tooth and individual case.
