Root canal therapy is needed when the nerve of a tooth is affected by decay or infection. In order to save the tooth, the pulp, nerve, bacteria and any decay are removed and the resulting space is filled with special medicated, dental materials, which restores the tooth to its full function.
Having a root canal done on a tooth is the treatment of choice to save a tooth that would otherwise need to be removed. It is highly successful, and most of the time a relatively simple procedure with little or no discomfort. Best of all, it can save your tooth and your smile.
