Treatment of a canal

When the nerve of your tooth is infected, a root canal allows you to keep your tooth rather than having to extract it. By keeping your natural tooth, you prevent other teeth from losing their alignment and causing problems in the jaw. You also avoid having it replaced by an artificial tooth.


What is root canal treatment?


Root canal therapy, also known as endodontics, involves removing infected, damaged or dead pulp from the tooth. The space inside the hard layers of the tooth is called the channel. The latter is filled with a soft tissue called dental pulp. This tissue contains the nerves and blood vessels that allow the tooth to grow.


Bacteria (microbes) that enter your teeth through deep caries, cracks, or damaged fillings can lead to an abscess. It is the infection of the dental pulp which is at the origin of this abscess. In this case, the pulp must be removed. The abscess can cause pain or inflammation. Dr. Audette can detect the infection from a dental X-ray or by observing other changes on your tooth. If left untreated, the abscess can lead to serious oral health problems.


What is root canal treatment?


The dentist performs a local anesthesia;

To prevent the bacteria in your saliva from coming into contact with your tooth during treatment, he places a dam around the tooth

It makes a small opening in the tooth to access the damaged canal and pulp;

Using precision instruments, he removes the pulp by cleaning and widening the canal;

Then he fills and seals the canal;

Then, he closes the tooth with a temporary or permanent filling.


Restoring the tooth after the root canal treatment


After a root canal, your tooth needs to be restored to give it back, as much as possible, its original function and appearance. If your root canal treatment was done by an endodontist, the endodontist will fill the tooth with a temporary filling and your treating dentist will restore your tooth.

Dr. Audette will restore your tooth with a permanent filling or crown. The type of restoration will depend on the strength of the remaining portion of the treated tooth. If it is a posterior tooth, Dr. Audette will probably use a crown because chewing puts a lot of pressure on these teeth. If the remaining portion of the treated tooth is insufficient, your dentist may use a pivot to hold the crown in place.
