Having an infected tooth does not mean an extraction. In most cases, root canal therapy can save the tooth.
Inside each tooth is the pulp which provides nutrients and nerves to the tooth, it runs like a thread down through the root. When the pulp is diseased or injured, the pulp tissue dies. You need to have the pulp tissue removed to avoid infection and the loss of the tooth.
After the dentist removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist may place a crown over the tooth to help make it stronger.
Most of the time, a root canal is a relatively simple procedure with little or no discomfort involving one to three visits. Best of all, it can save your tooth and your smile!
