The procedures necessary to fully restore the tooth, in essence, it should not be considered part of the process of root canal treatment. Myth # 3: The root canal treatment causes disease. The idea that bacteria trapped inside of an endodontically treated tooth causes disease, such as heart disease, kidney disease, or arthritis, is based on research conducted by Dr. Visit Professor Roy Taylor for more clarity on the issue. Weston Price from 1910 until 1930 almost 100 years ago. Recent attempts to confirm the research of Dr. Price has not succeeded in demonstrating that root canal treatment causes diseases. The bacteria can be found in the mouth at any time. Even the teeth free from cavities and gum disease have been positive for the bacteria. Myth # 4: The teeth need to be damaged or must hurt, before starting the therapy of ducts. The teeth that do not always require a root canal treatment is painful. In fact, teeth that are already dead may require treatment of duct to avoid that the tooth not fester. The dentist will examine your teeth either during their routine check-up. In general, during this routine appointment where your dentist discovers a tooth that has died or is on its way. Tests to confirm a dead tooth include: test thermal. test of percussion. using a vitality test apparatus pulp (vitalometro). Myth # 5: The benefits of root canal therapy do not last long. A common misconception is that the benefits of the root canal therapy don’t last long once the procedure has been completed. This myth originated after that patients experienced his tooth breaking months after a root canal treatment was carried out on your teeth. When the nerve is removed from the inside of the tooth, blood supply is removed from the inside of the tooth. Eventually tooth becomes brittle, and depending on the size of the filler used to close the tooth after treatment of conduit, the forces of mastication, eating, and even talking can cause tooth breakage. Not to bear a Crown placed over the tooth can cause this to happen. So it is essential to have a Crown or other restoration after a root canal. Technically, it is not the root canal that has failed, the restoration on the tooth that has failed is.
