Root Canal Therapy in North York, ON

Root canal therapy may be required when the nerve of a tooth is affected by decay or an infection. We will remove the pulp (i.e. the living tissue inside the tooth), nerves, bacteria, and any decay to help save the tooth.

Afterwards, we fill in the resulting space with specially formulated dental materials. This procedure works to restore the tooth to its full function.

When do you need a root canal?

Several signs indicate you may need root canal therapy. Some of these include:

  • Pain in your jaw, face, or other teeth
  • Swollen gums
  • Tooth discoloration
  • Sensitivity to hot or cold foods or drinks
  • Inflammation, infection, pain, and sensitivity after a dental injury
  • Loose tooth or several teeth

While these do not necessarily mean you need root canal therapy, they could be signs of other problems with your teeth and gums.

Please feel free to contact our North York dental office to schedule a consultation if you experience any of these issues. We will help you know if a root canal surgery will be right for you.

Procedure and possible pain

The treatment itself involves cleaning out the decay and disinfecting the root of your tooth before filling it in.

A root canal surgery is not as painful as you think. Your dentist will administer an anesthetic to reduce discomfort during the procedure.

We may offer you antibiotics after surgery to help prevent or stop an infection from developing. We can also suggest an over-the-counter painkiller. 


At Leslie Smile Solutions, we strongly encourage patients to care for their teeth and gums with consistent and good oral care. Doing so can help you prevent everyday problems like cavities, among other dental issues that can, later on, lead to a root canal procedure.

Here are some tips to help you maintain your oral health:

  • Regular brushing
  • Flossing
  • Using fluoride
  • Nutritious eating
  • Dental checkups
