Root Canal Therapy
Sometimes when a problem becomes more extensive, a root canal may be necessary to treat the pain or infection you are experiencing and keep you from losing the tooth involved. Although they have received a bad reputation, a properly done root canal is no more uncomfortable than having a cavity filled and is a fairly routine procedure.
The most common cause for needing this treatment is a cavity that has gotten large enough to introduce harmful bacteria to the nerve of the tooth, resulting in an infection or abscess. A root canal might also be necessary due to trauma, multiple fillings over the years, or as the first step of repairing a severely broken down tooth. An abscessed tooth will often cause swelling and pain and if left long enough, can even travel to other parts of the body causing more widespread problems.
A root canal is performed with local anesthetic the same way a filling is done. During the procedure, Dr. Leong will use special tiny instruments and cleaning solutions to sanitize the inside of the tooth and then he will fill and seal off the resulting space to prevent further infection and discomfort. Most teeth that have been treated with a root canal will require a crown to protect the tooth from cracking or breaking. Because the quality of your care is of utmost importance to Dr. Leong, he will sometimes refer you to a specialist for a root canal procedure to ensure that complex or difficult cases will not have any problems in the future.
