Is pain after a root canal normal?
Yes. Mild to moderate tenderness on biting for a few days is normal, because the tissue around the root needs time to settle. The pain should ease day by day.
How long does pain last after a root canal?
It usually eases within a few days. If it gets worse after the third day instead of better, call the clinic.
What helps with the pain?
Take the painkiller the doctor recommended as directed, avoid chewing on the tooth, and keep brushing and flossing as usual.
When is pain after a root canal a warning sign?
Call the clinic if new or growing swelling appears, the temporary filling falls out, the tooth feels high when you bite, or you have a fever.
If swelling spreads toward the eye or neck, or swallowing or breathing becomes difficult, go to the nearest emergency department straight away.
Other questions patients ask
Can I chew on the tooth after a root canal?
Avoid heavy chewing on it until the final filling or crown is fitted, as the tooth is more likely to break before then.
