A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected.
Root canal procedures are performed when the nerve of the tooth becomes infected or the pulp becomes damaged. During a root canal procedure, the nerve and pulp is removed and the inside of the tooth is cleaned and sealed.
What Are the Signs that a Root Canal Is Needed?
Signs to look for include:
- Severe toothache pain upon chewing or application of pressure
- Prolonged sensitivity/pain to heat or cold temperatures (after the hot or cold has been removed)
- Discoloration (a darkening) of the tooth
- Swelling and tenderness in the nearby gums
- A persistent or recurring pimple on the gums
- Sometimes no symptoms are present
