Root canal treatment

The viability of the tooth is compromised when the pulp of the tooth is infected, damaged and/or dead. In order to save the tooth, the dentist must proceed with a root canal treatment. At Centre Dentaire NP, your dental office in Kirkland, in the West Island of Montreal, the dentist will use an apex locator to help facilitate the location of the apex (end of the root) to help limit the risk of complications.

Why choose a root canal treatment?

A root canal treatment is a last resort to save the tooth when the pulp (internal component of the tooth that holds the blood vessels and nerves), is infected with bacteria. This can occur when a dental cavity grows large, fractured tooth or when a dental filling is broken. When bacteria reach the pulp of the tooth, it will slowly begin to lose its vitality and cause several consequences. These are:

> Fragile tooth
> Toothache and/or pain
> The formation of an abscess
> The spreading of an infection

An essential and routine procedure

In order to prevent not only the reasons mentioned above, it becomes necessary to remove the damaged pulp to avoid extracting the tooth and to have to replace it. A root canal can help relieve dental pain and the spreading of the infection. This treatment is done with the use of local anesthetics and is generally not painful to our patients. The following are the steps for a root canal:

  • The tooth is isolated with the use of a dental dam. This will work to prevent the spread of bacteria to the saliva and the rest of the dentition.
  • The removal of the pulp: With the help of precision tools, the dentist will make an incision in the tooth to gain access to the dental pulp. He/she will then remove the pulp with specific tools and instruments. The dentist may enlarge the canals to ensure they are well cleaned and rid of bacteria.
  • The cleaning and replenishing of the canal: once the canal is cleaned of the infection, the dentist will go ahead and fill it with a material called “gutta percha”.
  • Closing the incision made: the dentist will fill the area with composite (a dental filling material). In certain cases the dentist will highly recommend a dental crown to ensure that the tooth stays strong.

Root canal treatment myths

1. It is not a painful procedure

It is not the treatment itself that is painful but rather the bacteria that act upon the nerves that cause the pulp to react and cause pain. The root canal treatment in fact helps relieve pain.

2. It is a long and complex treatment

At Centre dentaire NP, your dental office in Kirkland, we use a apex locator to ensure that the length of the treatment is as short as possible.

3. A root canal treatment requires several dental visits

With the use of new technologies and the apex locator, the root canal treatment can be done and completed within one dental visit.

4. The root canal treatment comprises of several risks

The apex locator allows the dentist to ensure that all the different root canals of the tooth are well sealed which helps reduce the risk of residual infection.
