Do you need a root canal?

Millions of teeth are treated and saved every year with root canal procedures.  Prolonged sensitivity to heat or cold, tenderness when chewing, discolouration or swollen gums (abscess) are signs this treatment is necessary.  It is most often caused by deep decay, cracks, injury or repeated work on a specific tooth.




What are root canals and why are they necessary?

Inside every tooth is soft tissue called pulp that contains blood vessels and nerves.  If the pulp becomes infected and damages the nerves, it must be removed from the canals it lives in.  The canals are shaped, cleaned, filled and sealed for protection.

Follow up procedures.  Restoration.

  • Without a nerve, the tooth becomes brittle and susceptible to fracture.  Placing a crown on the tooth is one option to protect and restore it to full function.
  • If a crown is not used, the treated tooth may discolour.  This is of no medical concern and tooth whitening is a widely used and excellent solution.
