Root Canal Therapy at Midtown Toronto

Root canal therapy is needed when the nerve of a tooth is affected 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.

A natural biocompatible material called "gutta percha" is used for the main fill of the root. This material is extracted from tropical trees native to Southeast Asia and northern Australasia. Gutta Percha is the natural latex produced from the sap of these trees, particularly from the species Palaquium gutta.

There are several types of bridges. Porcelain fixed bridges are most popular because they resemble your natural teeth. This type of bridge consists to two crowns that go over two anchoring teeth (abutment teeth) and are attached to pontics (artificial teeth), filling the gap created by one or more missing teeth.

Having a root canal done on a tooth is the treatment of choice to save a tooth that otherwise would have to be removed.

Root canal treatment is highly successful and usually lasts a lifetime, although on occasion, a tooth will have to be retreated due to new infections.

Signs and symptoms for possible root canal therapy:

• An abscess (or pimple) on the gums.
• Lingering sensitivity to hot and cold.
• Severe tooth pain.
• Sometimes no symptoms are present.
• Swelling and/or tenderness.

Reasons for root canal therapy:

• Decay has reached the tooth pulp (the living tissue inside the tooth)
• Infection or abscess has developed inside the tooth or at the root tip
• Injury or trauma to the tooth

What does root canal therapy involve?

A root canal procedure requires one or more appointments. While the tooth is numb, a rubber dam (a sheet of rubber) is placed around the tooth to keep it dry and free of saliva. An opening is made on top of the tooth and a number of root canal files and low vibration rotary instruments are placed into the opening removing the pulp, nerve tissue, and bacteria.

If tooth decay is present, it will also be removed. Once the tooth is thoroughly cleaned and disinfected, it is sealed with either a permanent filling or, if additional appointments are needed, a temporary filling will be placed.

At the next appointment, usually a week later, the roots and the inside cavity of the tooth will be filled and sealed. A filling will be placed to cover the opening on top of the tooth. In addition, all teeth that have root canal treatment should have a crown (cap) placed. This will protect the tooth and prevent it from breaking.
