Root Canal Treatment
When the nerve of your tooth becomes infected, a successful root canal treatment lets you keep the tooth rather than having to pull it out. Keeping your tooth helps to prevent your other teeth from drifting out of line and causing jaw problems. Saving a natural tooth avoids having to replace it with an artificial tooth.
What is a root canal treatment?
Root canal treatment, also known as endodontic treatment, is the process of removing infected, injured or dead pulp from your tooth. The space inside the hard layers of each tooth is called the root canal system. This system is filled with soft dental pulp made up of nerves and blood vessels that help your tooth grow and develop.
When bacteria (germs) enter your tooth through deep cavities, cracks or flawed fillings, your tooth can become abscessed. An abscessed tooth is a tooth with an infection in the pulp. If pulp becomes infected, it needs to be removed. An abscessed tooth may cause pain and/or swelling. Your dentist may notice the infection from a dental X-ray or from other changes with the tooth. If left untreated, an abscessed tooth can cause serious oral health problems.

Who does this procedure?
Your dentist may do root canal treatment or refer you to an endodontist. An endodontist is a dentist who has completed a university postgraduate specialty program in endodontics. Endodontics is a specialty of dentistry concerned with the treatment of the dental pulp or nerve of the tooth.
If your child's primary (baby) tooth is damaged, your dentist may refer you to a pediatric dentist for this procedure. A pediatric dentist has at least 2 years of extra university training in treating children.
How is a root canal treatment done?
- The dentist gives you a local anesthetic (freezing).
- To protect your tooth from bacteria in your saliva during the treatment, the dentist places a rubber dam around the tooth being treated.
- The dentist makes an opening in the tooth to reach the root canal system and the damaged pulp.
- Using very fine dental instruments, the dentist removes the pulp by cleaning and enlarging the root canal system.
- After the canal has been cleaned, the dentist fills and seals the canal.
- The opening of the tooth is then sealed with either a temporary or permanent filling.
What else should I know?
Root canal treatment may be done in 1 or 2 appointments. After root canal treatment, your tooth may be tender for the first week or two. Bad pain or swelling is NOT common. If this happens, call your dentist or endodontist.
You can still get a cavity or gum disease after a root canal treatment. Root canal treatment does not protect your tooth from other types of damage. With proper care and regular dental visits, the tooth could last as long as your other teeth. Most of the time, a tooth that has had a root canal treatment can be saved. However, there are cases where everything possible has been done to save a tooth and still the tooth must be extracted (pulled).
