Root Canal Therapy

Root Canal Therapy Fast Facts

  • A root canal may be needed, even if the tooth isn’t painful.
  • A tooth should always be crowned after a root canal.
  • A root canal is meant to save a tooth, it does not kill the tooth.

Root Canal Therapy (RCT) – what is it?

Root canal therapy gets rid of bacteria in the infected root canal. RCT also prevents reinfection and saves the natural tooth.

What happens during Root Canal Therapy?

  1. The inflamed or infected pulp is removed.
  2. The tooth is cleaned and disinfected.
  3. Then it is filled and sealed.
  4. A dental crown is placed on the tooth. (May be optional, but it is recommended)

What Do Root Canals Look Like?

Is Root Canal therapy Common?

Root canal treatment is possibly the most widely recognized dental treatment. RCT treatment cures the infection that is at the center of the tooth. Every tooth has a root canal system, if this system becomes infected it could create trouble.

What can cause a tooth infection?

Infections are commonly caused by bacteria or poor oral care. These infections can promote tooth decay, leaky fillings, and damage to the teeth.

Who Needs Root Canal therapy?

Common symptoms that suggest that you may need a root canal include:

  • Persistent lingering pain or sensitivity to cold or hot foods/beverages.
  • Excessive toothache pain when applying pressure or chewing.
  • Darkening or discoloration of the tooth.
  • Persistent or recurring pimple on the gum.

If you experience any of these symptoms, we strongly recommend you see a dentist. Through X-rays and other tests, our dentists will identify and treat your dental pain.

Are you concerned you may need root canal therapy?

How do I know I need a root canal?

Root canal therapy is recommended in cases when the tooth is considered restorable (can be fixed), but it is either abscessed, fractured, heavily decayed, or otherwise causing pain. The most common type of root canal therapy is non-surgical, the other is surgical root canals.

How is root canal therapy performed?

Access Opening

An opening the dentist makes in the tooth to perform the surgery.


The measuring is completed by a special device called an “apex locator”, and x-rays.

Cleaning and shaping

A procedure involving the physical shaping of each canal with specialized instruments such as endodontic files and the chemical disinfection of the canal(s).


This is the filling and sealing of each canal.

Permanent filling

A permanent filling material is placed to prevent the re-entry of bacteria into the sealed and disinfected canal(s).

Post Insert

A dentist may place a post in one or more of the canals to help retain the final restoration.

Dental Crown cementation

After the root canal has been in the tooth for some time, a crown could be recommended.

The crown is the preferred final restoration for many root canal-treated teeth because it lowers the risk of fracture (root canal teeth can become brittle over time).
