Root canal treatment is necessary when the soft tissue inside your teeth containing blood vessels, nerves and connective tissue becomes inflamed or diseased. During root canal treatment, the dentist removes the diseased tissue. The soft tissue chamber and root canal(s) of the tooth are then cleaned and sealed. If the infected tissue is not removed, pain and swelling can result, and your tooth may have to be removed. A root canal is a relatively simple procedure with little or no discomfort involving one to three visits. Best of all, it can save your tooth and your smile.
Causes of an infected tissue could include:
- A deep cavity
- Repeated dental procedures
- A cracked or broken tooth
- Injury to the tooth (even if there’s not a visible crack or chip)
