The root canal system of a tooth is like a tree root system. At the center of each root is a canal filled with pulp tissue containing blood vessels and nerve endings. For different reasons bacteria can enter the system and cause infection and inflammation of the sensitive nerves. The purpose of root canal therapy is to cleanse the system and prevent further spreading of the bacteria to the jawbone. Critical to the success of the treatment is that the whole root system, the main canal and the smaller accessory canals, is cleaned and filled to prevent further infection and inflammation.
Today, there are different methods of treating a root canal. The difference is in the way the root canal is prepared, the filling materials used, and the way they are introduced into the root canal system in order to seal as many root branches as possible. When necessary, a sterilization of the canal may be carried out using laser technology.
This involves shaping the root system manually with the use of tiny files, cleaning and removal of infected pulp tissue, and then filling the main canals with an anti-microbial paste. The openings are then sealed with a natural rubber material (gutta percha). A subsequent x-ray of the tooth is taken to ensure the successful result of the treatment.
This treatment method may fail if all the canals within the root system are not decontaminated and filled successfully, or if, after time, the anti-microbial paste degenerates, leaving space for a renewed bacterial invasion and subsequent infection.
Treatment under Sedation
We are pleased to be able to offer this treatment under a general anesthetic for patients who prefer this alternative to a local anesthetic. We advise you on the treatment possibilities, explain all the procedures, and together we decide on the treatment that suits your needs.
At our practice we specialize in root canal therapy using thermoplastic condensation, a method which provides the best possible sealing of the canal. Highly flexible nickel titanium instruments that reach into very narrow or curved canals are used to clean and prepare the root canal system. A specialized computer generated electrometric instrument measures the length of the canal so that the usual x-ray examination and radiation exposure can be eliminated. The canal is filled with warm plasticized gutta percha. Its liquid consistency ensures that all canal surface irregularities and accessory canals are fully sealed.
Due to our long experience performing root canal therapy using different procedures, we can recommend thermoplastic condensation as the best procedure available today. This technique has an excellent record of success and provides a strong and long-term foundation on which we can successfully reconstruct the tooth.
