If a cavity is left untreated and decay extends into the central, living portion of the tooth, bacteria can travel into this pulp area and cause tooth pain or an abscess. You may experience toothache, sensitivity to hot or cold, tenderness to pressure when chewing, increased sensitivity when you lie down or even swelling. These are signs that decay has progressed to the point where a root canal is required to save the tooth.
Many people have anxiety about having a root canal but there is no need to be apprehensive. We will ensure that you have adequate freezing and your experience should be no different from a routine filling although a root canal usually takes longer to complete.
A filling can be placed after the root canal is completed, however a crown is the best long –term restoration for any root canal treated tooth. A large portion of tooth structure is lost when a root canal is completed which can affect the strength of the tooth and a crown helps to prevent fracture that is so common in these teeth.
