Root Canals

Clinique Dentaire Dr. S. Sgro & Dr. J. Lang | Greenfield Park, Montreal Dentist

At Clinique Dentaire Dr. S. Sgro & Dr. J. Lang in Greenfield Park, our dentists provide root canal therapy if the inner nerve of your tooth becomes infected.


What is Root Canal Therapy?

Root canal treatment, also known as endodontic treatment, is the process of removing infected, damaged or dead nerve from your tooth.

The space inside the hard layers of each tooth is called the root canal system. This system is filled with nerves and blood vessels that help your teeth grow and develop. When bacteria enters your tooth through deep cavities or cracks, your tooth can become abscessed. An abscessed tooth is a tooth with an infection in the nerve.

If the nerve becomes infected, it needs to be removed. An abscessed tooth may cause pain and/or swelling. If left untreated, an abscessed tooth can cause serious health problems.
