Diagram of an infected and abscessed tooth root from the AAE
For readers who aren’t endodontists (dentists who specialize in treating the ends/roots of the teeth), we can break down this explanation a little further. Inside the innermost part of every tooth is a soft tissue known as pulp, or pulp tissue. This tissue is made up of blood vessels, nerve endings and connective tissue that help a tooth and its root grow when developing. Healthy adult teeth are able to survive even without this pulp with the help of other healthy tissues surrounding them. However, when this inner pulp becomes irritated or infected, it must be removed in order to stop dental pain and prevent tooth loss.
Root canal procedures, then, are treatments where a trained dentist or endodontist will carefully remove the affected pulp from inside the tooth. Afterward, the remaining canal is cleaned out and sealed with a dental sealant. More on this process near the end of this blog post!
