Canal treatments in DDO


When the nerve of a tooth becomes infected, performing a canal treatment helps in preventing removal.

What is a root canal treatment?

A root canal treatment, also known as endodontic treatment, is the process of removing infected, damaged or dead pulp from the tooth. The space inside the hard layers of each tooth is called thecanal. It is filled with soft dental pulp consisted of nerves and blood vessels that allow teeth growth and development.

Bacteria that enter a tooth via severe cavities, cracks or damaged fillings can lead to an abscess forming inside the canal. This is due to dental pulp infection. Once an abscess has been detected, dental pulp needs to be removed promptly, as the abscess can cause a lot of pain and inflammation. If left untreated, an abscessed tooth can cause serious oral health problems.

One of our qualified dentists in the West Island can detect the infection with a quick x-ray.

The procedure

The dentist injects a local anesthetic. Then, he pierces a small hole in the tooth in order to access the root canal system and the damaged pulp. The pulp is then removed using very fine instruments. Once the canal has been cleaned, the dentist fills and seals it before installing a temporary filling. A dental crown is recommended following treatment to help preserving the tooth.

Root canal retreatment

Most root canal treatments are successful, but in some cases, a second root canal treatment is needed. This is called root canal retreatment. The filling is taken out and the tooth cleaned a second time.
