Root Canal Therapy:
When the nerve inside a tooth becomes infected as a result of decay or trauma, the options are extracting the tooth, or saving it with root canal therapy (also called endodontic therapy). This process involves removing the nerve from inside the root of the tooth and then filling it and then commonly placing a crown on the end. This procedure takes a few appointments to complete and is often the preferred option. Sometimes however, the tooth is not able to be saved and extraction is the only option.
