Root canal treatment is considered a part of endodontic treatment. The root canal of a tooth (tooth root) can become inflamed or infected, causing swelling of the gums and toothache. It can also be required in other dental cases that can help save and restore a tooth.

Root canal remains, for many patients, the only viable option to retain a tooth that has suffered severe damage or tooth root with inflammation or infection.

Root Canal Definition

The root canal therapy can be described as the removal of the infected pulp (tooth tissue) from inside of the tooth canals. Once the dentist cleans and disinfects tooth canal(s) the next step is to have a tooth filled and sealed with a natural rubber-like material called gutta-percha. Depending on your situation, the opening of the tooth is then sealed with a temporary or permanent tooth filling to protect that tooth from further infection.



Step by step description of the procedure:

  1. Our dentist gives you a local anesthetic (freezing) to numb your tooth.

  2. In order to protect your tooth from bacteria in your saliva during the treatment, our dentist places a rubber dam around the tooth that requires root canal therapy.

  3. A dentist makes an opening in the tooth to reach the root canal or canals and the damaged pulp.

  4. Using special dental instruments, the dentist removes the pulp by cleaning and enlarging the root canal.

  5. After the root canal cleaned, the dentist uses a natural rubber-like material called gutta-percha and seals the canal with a dental filling.

  6. The opening of the tooth is sealed with either a permanent or temporary filling to prevent new infection from entering the root canal again.

    Root Canal Explanation

    There is a change you can still get a tooth cavity or a gum disease after a root canal treatment and might need a repeated dental procedure. Root canal treatment does not eliminate the chances of your affected tooth from other types of damage.

    Making a priority to get a regular dental check-up and proper care for root canal tooth can make it last as long your healthy teeth. Most of the time, a tooth that went through 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). Our goal is always to do everything we can to repair and save your natural tooth.

How is a tooth restored after root canal treatment

After a root canal treatment, your tooth has to be fixed to look and feel like a natural tooth.

A dentist can restore and replace tooth using a dental crown, porcelain bridge or a dental implant. Your dentist may use a permanent filling or a dental crown to restore your tooth. The choice of what restoration will be appropriate will depend on the strength of the tooth that's left. A back tooth (molar) will likely need a crown because those teeth are your chewing teeth and can put a great deal of force on back teeth.

If there is not enough of the tooth surface left, dental posts may be used to help support and straighten the crown.


Root Canal Treatment Success Rate

Root canal therapy is routinely performed successfully by dentists across Ontario. A general dentist or endodontist can perform a root canal treatment. While a most general dentist can perform a root canal treatment, more complicated cases are referred to an endodontist. A dentist who has taken advanced training in endodontic therapy is called an endodontist and may be recommended by your dentist for more complex cases.

How long does it take to do a root canal

Root canal treatment may be done in one(1) or two(2) appointments. After root canal treatment, your tooth may be tender for the first week or two. You should NOT feel bad pain or swelling. If this occurs, call our dentist.

Make sure to practice good oral hygiene after your treatment, this includes brushing and flossing your teeth. Regular dentist visits will allow the dentist during regular dental check-ups to make sure your other teeth do not get decayed to the point that the tooth root becomes infected and root canal treatment is required.
