Root Canal Therapy:
Tooth decay can progress to the soft inner part of the tooth where the nerves reside. When the infection spreads this far within your tooth, a regular filling is not enough to halt the spread of the infection or provide relief from discomfort. A root canal treatment or endodontic therapy becomes necessary in such cases; it is the treatment of choice to save a tooth that would otherwise require extraction.
This treatment usually requires one or more visits. If more than one appointment is needed, they are scheduled a week from each other, the first is focused on cleaning, the remaining shaping, and filling the tooth’s root canal system. The spacing of visits allows for easier management of any flare-ups that may develop and also gives the dentist the chance to monitor the progress of the tooth’s healing process.
It is necessary to take a number of radiographs (x-rays) during the root canal treatment to determine the position of instruments and filling materials within the canal. These are small x-rays that have a very minimal radiation dose.
Once the tooth is deemed to be healing properly and the root canal a success, a permanent restoration, usually a crown is placed to prevent any future tooth fracture.
