Dental Infection Treatment

Drainage and incision:

Our surgeon in Toronto, ON, will make a small cut in the pocket of infection to drain the pus. The dentist might place small rubber on the open area to help drainage.

Root canal:

This procedure helps cure the infection while saving your tooth. During the procedure, your dentist removes the infected pulp of the tooth, filling the space with the material to help prevent another infection. The pulp of your tooth is important when the team is growing, but once they are mature, they can survive without it.

After the root canal procedure, you are told they will be back to normal. However, you might need a dental crown to protect the root canal. If you take good care of the restored tooth, it will last a lifetime.

Tooth extraction:

Sometimes dentists are unable to save your tooth and may need to extract or pull the tooth to allow the past to drain from the pockets.


If your infection is limited to the abscessed area, you might not require antibiotics, but your dentist might recommend you take them to help with your dental treatment. It’s essential to know that even though antibiotics will help fight off the remaining bacteria, they won’t eliminate the cause of the tooth infection.
