Root Canal Therapy

A root canal is a form of treatment used to repair and save a tooth that has been infected due to a deep cavity or crack. To treat the tooth, the infected pulp and/or nerves of the tooth are removed and then the cavity cleaned. If treatment is not sought, bacteria may build up at the tip of the root and the infection can spread to the bone. Typically this results in substantial pain, swelling and an eventual loss of the tooth.

What are the signs that a root canal is needed?

  • Severe tooth pain while chewing
  • Your tooth pain wakes you up at night
  • Teeth that are highly sensitive to hot or cold, with the sensitivity lingering for some time.
  • Discoloration or darkening of the tooth
  • Swollen gums in the area of the infected tooth

What does the treatment involve?

First, an opening is made into the crown of the tooth in order to remove the infected pulp. The canal will then be thoroughly cleaned by Dr. Derrick A. Johnston, followed by a permanent and natural looking filling or crown being placed.


In certain circumstances, we may elect to perform this procedure in multiple visits, and put a temporary crown on the tooth after the cleaning. The temporary crown will be taken off at the proceeding visit with more infected material being removed and more cleaning to be done. When the cleaning has finished, a permanent filling or crown will be administered.

With such a high rate of success, root canals are a standard and common practice that can help save your tooth and last a lifetime. If you are suffering from any of the above signs or symptoms, maybe root canal therapy is in order.
