Root Canal Therapy

Call Now

At Marquis Dental Group in downtown Saskatoon, our dentists may recommend root canal therapy when the nerve in your tooth is inflamed or infected.


What is root canal therapy?

Root canal therapy may be necessary to treat an irreversibly inflamed nerve or abscess caused by decay or infection. In order to save the tooth, the pulp (the living tissue inside the tooth), nerves, bacteria, and any decay are removed and the resulting space is filled with special, medicated, dental materials, which restore the tooth to its full function.

Signs and symptoms of possible root canal therapy:

  • Severe toothache pain
  • Sensitivity to hot and cold
  • Swelling and/or tenderness
  • An abscess (or a pimple) on the gums
  • Sometimes no symptoms are present

What are the steps involved in root canal therapy?

Step 1: An abscess has formed at the base of the tooth root causing infection and pain.
Step 2: A small opening is made in the tooth and the area is prepared for cleaning.
Step 3: The inside of the tooth and the root canal is cleaned out and disinfected.
Step 4: The canal is filled and the tooth is restored.
Step 5: Teeth that have had root canal therapy should be restored with a crown to protect them from a fracture.

What can I expect after my appointment?

After treatment, your tooth may still be sensitive, but this will subside as the inflammation diminishes and the tooth has healed.
You will be given care instructions from the dentist or hygienist after each appointment.
