A root canal procedure requires one or more appointments and can be performed by a dentist or endodontist (a root canal specialist).
While the tooth is numb, an access opening is made on the top of the tooth and a series of root canal files are placed into the opening, one at a time, removing the pulp, nerve tissue, and bacteria. Once the tooth is thoroughly cleaned, it will be sealed with either a permanent filling or if additional appointments are needed, a temporary filling will be placed. The number of visits necessary to complete the root canal will depend on several factors: the number of nerves (canals) in the tooth, the infected state of the nerve and the complexity of the procedure. Usually molars are more challenging than other teeth due to the anatomy of these teeth.
At the next appointment, usually within 7-10 days, the roots and the inside cavity of the tooth will be filled and sealed with special dental materials. A filling will be placed to cover the opening on top of the tooth. In addition, all teeth that have root canal treatment should have a crown placed eventually. This will protect the tooth and prevent it from breaking, and restore the tooth to its full function.
After treatment your tooth may still be sensitive. This is usually due to an irritation of the bone surrounding the tooth and may range from a mild discomfort in the area to an occasional episode of considerable pain. This discomfort will usually maximize in approximately 48-72 hours and then subside. You will be given care instructions after each appointment. Good oral hygiene and regular dental visits will aid in the life of your root canal treatment.
