Root Canal

Your dentist near Saint-Leonard - Root Canal

The root canal or devitalization consists of cleaning or emptying the tooth root, either because of a trauma or because it is decayed. During this treatment, the dentist’s role is to remove the dental pulp, which includes blood vessels and the tooth’s nerve.

Often, the causes justifying this treatment are the following

  • Deep cavity reaching the dental pulp
  • Irritated dental pulp, either by a filling or a trauma
  • An abscess at the tip of the root of the tooth
  • Tooth colour change
  • Gum appearance change

This list is not exhaustive. If you have a doubt, do not hesitate to contact us.

In some cases, the tooth has to be extracted, but our experience shows that in the majority of the cases, we are able to save the tooth thanks to the root canal. If you are afraid of this procedure, our treatment coordinator and our general dentists will be able to reassure you.
