A root canal is the most effective way to treat an abscessed tooth. Often, the only alternative is to extract the tooth. If left untreated, the infection can spread to other parts of your mouth and body, causing potentially severe health problems. An untreated tooth infection will also be painful and elevate the risk of tooth loss.
A tooth can become infected when a cavity or deep crack in your tooth leaves its interior exposed and vulnerable to bacteria. Common signs of an abscessed tooth include:
- Severe pain when you chew or bite
- Swollen or tender gums
- Pain that radiates through your jaw
- Tooth discolouration
- Increased sensitivity to hot and cold
- Fever
A root canal may also be necessary to treat a dental emergency such as a severely chipped or broken tooth. If the damage extends to the pulp, your dentist may use a root canal to help prevent an infection and reinforce the tooth.
