A root canal is a very common treatment performed by specialists called endodontic. Your teeth have a core of blood vessels and nerves at their center. This living tissue is called the pulp and is in a space called the root canal. The number of root canals in each tooth varies depending on how far back it is in your mouth. Front teeth often have one root canal, while back teeth may have three or more. The pulp tissue does contain nerve fibers it is also composed of arteries, veins, lymph vessels and connective tissue. The pulp can become diseased or injured and thus is unable to repair itself. The pulp then dies and endodontic treatment is required.
The procedure is usually under local anesthetics. The dentist will begin by cleaning the thorough tooth. When the pulp chamber becomes exposed, any infected tissue i n the pulp chamber will then be removed and any remaining nerve tissue will be removed from the root canals. Once this is completed, your root canal is widened so that it is ready for filling. Before filling, your tooth will be disinfected and a material called gutta-percha will be pushed into the pulp to ensure a tight fit. A temporary filling is usually applied before being swapped for a permanent crown or filling at a follow up visit.
This treatment removes blood vessels and nerves from a tooth which are infected. It may also be required to remove a live nerve from a tooth. A root canal infection can be caused by different things including decay, injury and gum disease. Sometimes a live tooth may have insufficient tooth substance to retain a crown so the tooth may have to have root canal treatment and be restored with a post-retained crown
