Root Canal

Root Canal Treatment Downtown Toronto

An x-ray of endodontics procedure by Dr. Ammar Taimish at Norton Dental Downtown

Endodontics, more commonly called root canal treatment, is a dentistry specialty dealing with tooth pulp (the center of a tooth) abnormalities and issues surrounding the root of a tooth. 

Once the tooth's pulp is inflamed or has become infected, it can be painful. Dr. Ammar Taimish at Norton Dental Downtown will make sure your teeth remain healthy and strong.


In endodontics, a dentist will remove the inflamed/infected pulp, clean and shape the inside of the canal and then fill and seal the space to prevent further infection. Afterwards, the placement of a crown or other restoration is performed in order to protect the tooth and give it a natural appearance with the functionality of a healthy tooth. With proper oral care, these restorations may last a lifetime.

The cost of root canal treatment varies within the complexity of the case, but most dental insurance plans provide some coverage for such treatment. However, keep in mind that endodontic root canal treatment and restoration are generally less costly than the alternative which is tooth extraction and replacement with an implant and dental crown.

Endodontic Root Canal Procedure

Pulp therapy, also referred to as a pulpectomy, is a fairly common non-surgical procedure in endodontics where the dental pulp is extracted from its chamber in order to treat oral pain that may be caused by teeth with narrow or blocked canals and whose positioning may be problematic 

In some cases however, the removal of abnormal pathological tissues, the replacement of knocked out teeth and the repair of cracked teeth may require surgical endodontic treatment such as the following:

  • An apicoectomy is the process in which the root tip is surgically removed along with any encompassing infected tissue of a tooth that is abscessed. This procedure is also referred to as a root-end resection.
  • A hemisection is an endodontic surgical procedure that is used to cut a tooth with two roots in half. This procedure is done when periodontal disease has reached the roots of the gum and root canal treatment has failed. It is a procedure which is seldom done, but there are some circumstances which call for it.
  • Bicuspidization is a surgical procedure in which a multi-rooted tooth is sectioned through the furcation (the forked end of the tooth) and both halves of the tooth are retained.
  • Root end filling
  • Oral implants extend throughout the root canal to the periapical bone structure located at the tip of the tooth root, whereas some implants are simply anchored directly into the jawbone or gum tissue.
  • Bleaching the enamel or dentin
  • Teeth that were previously treated via root canal and require re-treatment
  • The posts and/or cores are placed to restore and strengthen each tooth. A core is composed of dental restorative and placed by a dentist in order to replace much of a tooth’s lost crown, which is the part of the tooth located above the gum line. Loss in the crown requiring a need for core placement can be caused by decay, fracture and previous root canal treatment. Cores are placed with dental filling material or other dental bonding restoratives. A post is a metal or carbon-fiber anchor used to stabilize the core of the tooth. A post is drilled by a dentist so that it follows the path of the filling material that was placed during root canal treatment. The post is only necessary and can only be placed if the patient has previously had root canal treatment. The post is drilled first, then the core is placed on top so that a crown can be placed, thereby fully restoring the tooth.

Root Canal Symptoms

  • Persistent pain or discomfort in the tooth
  • Sensitivity in the tooth to cold or hot foods or beverages
  • Tenderness in the gums when eating
  • Swelling
  • Discoloration in the tooth
  • Lymph node, jawbone or gum tenderness or draining.

If the dental pulp becomes infected or inflamed resulting from severe tooth decay, dental procedures are performed repeatedly on the tooth, or an injury is caused to the tooth such as a chip or crack, then endodontic root canal treatment is necessary. Endodontic root canal treatment can save most teeth.

Failure to perform a necessary root canal may result in the formation of an abscess, or an infected pus pocket near the end of the tooth root and cause pain. Even in cases where you don’t feel pain, the bone anchoring the tooth within the jaw may be damaged. Consult Dr. Ammar Taimish (Downtown Toronto Dentist) to find out what treatment plan is best for you.

When is tooth extraction necessary?

  • The roots of the tooth have be fractured
  • A tooth no longer has proper bone foundation
  • It is no longer possible to save the tooth
  • The root canals cannot be accessed
