What is a root canal?

Root canals are necessary to save teeth if decay has progressed to the nerve inside the tooth. A root canal might also be indicated when a tooth fractures into the nerve inside the tooth. During the procedure, the nerve and other infected tissue are removed from inside the tooth.The cleaned nerve chamber is then filled with a rubber-like material called gutta percha.When the nerve is taken out of a tooth, the blood supply for the tooth is also lost.The tooth becomes non-vital, or dead, but still can be functional for a patient’s lifetime if properly protected.A non-vital tooth is more brittle than a vital tooth, so to prevent the tooth from breaking, a porcelain or gold crown is usually placed over the tooth.
