What Is A Root Canal?

July 18, 2016 | Posted 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.

Sometimes, you may notice one or more of your teeth are feeling sensitive when you eat or drink something hot, cold, sweet, or sour. This sensitivity may be painful, often feeling like a sharp and sudden pain deep into your tooth. Typically, sensitive teeth are caused by your gums being pulled back and exposing the surface beneath them. This surface is called dentin, and is what makes up the inner parts and roots of the tooth. When this surface is exposed, it allows hot, cold, sweet, and sour foods to directly reach the nerves of your tooth, causing sharp pain. Other possible causes of tooth sensitivity include wear and tear due to brushing too hard, tooth decay, teeth grinding, and gum disease.
There are a number of different things you can do to reduce and control tooth sensitivity. First, make sure to brush and floss regularly using proper brushing and flossing techniques. Second, use a toothpaste made for sensitive teeth. Regular use of a toothpaste made for sensitive teeth should make them less sensitive. Third, watch what you eat, as large amounts acidic food and drink can cause tooth sensitivity. If the sensitivity continues, make sure you talk to your dentist about it. There are a few different things that your dentist can do to help reduce tooth sensitivity, such as applying white fillings to cover exposed root surfaces, applying fluoride varnishes to root surfaces, or applying dentin sealers.
