Root canal treatment is used to treat infection or inflammation affecting the tissue inside a tooth. It may help preserve a tooth that would otherwise need to be removed.
Possible warning signs
- Persistent toothache or pain on chewing.
- Prolonged hot or cold sensitivity.
- Swelling or tenderness near the tooth.
- Darkening or changes around a previously injured tooth.
Your dentist may use an examination and dental imaging to understand the condition of the tooth before recommending treatment.
When to book a dental consultation
If a dental problem is persistent, worsening, associated with swelling, fever, trauma, or difficulty eating, arrange an appropriate dental assessment rather than relying on online information alone.
