Root Canals - What Are They?

June 18, 2018 | Posted in Education

Root canals are necessary when the tooth’s pulp, which is composed of nerves and blood vessels, becomes infected or damaged. During the root canal procedure, the pulp is removed, and the inside of the tooth is cleaned and sealed. Common causes of pulp damage include cracked teeth, deep cavities, or another type of injury to the tooth. After the pulp becomes dead or infected and is left untreated, pus can build up causing pain.
The root canal procedure is made up of several steps:

  • First, an opening is made through the crown of a molar or the back of a front tooth.

  • Next, the damaged or infected pulp is removed, and the pulp chamber is cleaned.

  • After cleaning the chamber, it is permanently filled with a rubber compound called gutta-percha.

  • Finally, a crown is usually placed over the tooth to protect it and restore it.

With proper care, root canals can last your entire life. The tooth can still decay, so it's important to practice good oral hygiene. If you have any questions, or need a root canal yourself, contact us here at the Rideau Dental Centre by calling 613-230-7475.
