root canal dentist

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.


The root canal therapy can be described as the removal of the infected pulp (tooth tissue) from inside of the tooth canals. The pulp chamber of the tooth consist of nerves and blood vessels. When infected, dental pulp gets damaged and infected and needs to be removed and cleaned by the dentist. 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.


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 therapy 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.

Sometimes no signs present at all.

How is a root canal done?

  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 canal or canals and the damaged pulp (nerves and blood vessels).

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

  5. After the canal(s) 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.

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.

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.

It is common for dental benefits to provide coverage for the root canal procedure. It is commonly categorized under "Basic" dental services, although some dental insurances list it under "Major" coverage.

As a "basic" service, a root canal is often covered up to 80% of the procedure fee. If your dental insurance categorized a root canal under "Major" service, you could expect less coverage (frequently only 50%). You should check with your specific insurance plan as each benefit compensation is negotiated between your employee and the insurance company.
