Endodontic therapy, also known as a root canal, is a relatively painless treatment which aims at clearing infection as well as protecting the tooth from subsequent infections.
When a tooth is cracked or has a deep cavity, bacteria can enter the pulp tissue and germs can cause infection. If left untreated, an abscess may form. If the infected tissue is not removed, pain and swelling can result.
This not only puts your jawbones at risk for injury, but it is also detrimental to your overall health. Without the proper treatment, your tooth may have to be removed.
Teeth that require endodontic therapy are not always painful. However, signs you may need a root canal include:
- Severe toothache
- Pain upon chewing or application of pressure
- Prolonged sensitivity to heat or cold
- Dark discoloration of the tooth
- Swelling and tenderness in the nearby gums
How is endodontic therapy performed?
Root canal therapy is routinely done in one or two visits. After an examination, which includes x-rays, a diagnosis will be made and treatment options will be presented. If endodontic treatment is elected, a local anesthetic is then administered. The tooth is isolated with a thin sheet of rubber (rubber dam) to protect your throat from fluids and debris.
