Signs that may indicate a root canal is needed
Symptoms vary, and some infected teeth cause no pain at all. Any of the following are worth having evaluated promptly.
- Persistent, throbbing toothache, often worse when lying down
- Lingering pain after hot or cold, rather than a brief twinge
- Pain on biting, or a tooth that feels raised
- A darkening tooth, or a small bump on the gum beside it
- Facial swelling, which should be treated as urgent
