What is a root canal treatment?

The root canal treatment is described as the removal of the infected tooth tissue (pulp) from inside of the tooth's canals. When the dentist cleans & disinfects the root canal(s), the next step is to fill the tooth canal & sealed it with a rubber-like natural material named gutta-percha. The opening of the tooth is then closed off with a temporary filling or a permanent one. This protects the tooth from further infection.

When do you need a root canal or what causes you to get a root canal?

1. One of the most common signs you may need a root canal is when you get a severe toothache or sharp pain when chewing or applying pressure;

2. Discolouration of the tooth (tooth is darker than other teeth or turning gray);

3. Continues sensitivity (or pain) to cold or hot temperatures;

4. Swelling & tenderness in your gums;

5. A recurring or persistent pimple on your gums.

How is a root canal done?

1. First, our dentist administered local anesthesia (freezing) to numb your tooth.

2. To avoid any bacteria or saliva getting into a root canal during your treatment, the dentist places a rubber dam (a piece of rubber-like material).

3. Our dentist makes an opening in the tooth to allow the dentist to thoroughly clean the root canal or canals and the damaged pulp.

4. With special dental equipment, the dentist removes the pulp by cleaning and enlarging the root canal.

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

6. The opening of the tooth that was used to access damaged pulp is filled and sealed with either a permanent or temporary dental filling. This step prevents new infection from entering the root canal on the same tooth.

Can you get an infection after a root canal?

There is a chance you can still get a cavity or a gum disease after a root canal procedure & may require a repeated dental procedure.

How long does a root canal last?

Regular dental check-up & proper dental care for root canal tooth may make it last as long as your healthy teeth.

Most of the time, a natural tooth that had a root canal procedure can be repaired and saved. There are rare cases when everything has been done to save a tooth, yet, that tooth may need to be extracted (pulled). Our dentist's goal is always to do everything to repair & keep your natural teeth.


After a root canal procedure, your tooth has to be restored to look, feel and function like your natural teeth.

Signs of root canal

A dentist may restore & replace tooth using a dental implant, dental crown or porcelain bridge. Our 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 dental crown.

How successful is root canal treatment?

Root canal therapy is frequently performed successfully by dentists in Ontario. A general dentist's success rate is high as they often perform a root canal treatment; however, more complicated cases referred to an endodontist. A specialist dentist with advanced training in root canal therapy called an endodontist and a root canal treatment called endodontic treatment.

In instances where your root canal has been calcified, has abnormal root structure, severe inflammation or infection or a root canal procedure needs to be repeated, our dentist may refer you to an endodontist.


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

After your root canal treatment, it is essential to practice good oral hygiene. Good oral health includes brushing twice a day and flossing your teeth. Regular dentist visits will allow our dentist to conduct regular dental check-ups of your teeth and gums.

Regular dental check-ups allow our dentist to make sure your teeth and gums are healthy before any tooth get severely decayed and become infected.

How long will my root canal hurt?

A root canal can be painful and uncomfortable, especially if you waited for infection to spread. As soon as the dentist or endodontist administers local anesthetic you pay will go away and you will feel instant relief when root canal procedure is completed.

If you suspect you may need a root canal or not sure if your toothache caused by infection of your tooth root, call our office to schedule your appointment.
