How long do root canals hurt for
Discomfort after a root canal commonly improves over several days as the tissues around the root settle.
The short answer
Discomfort after a root canal commonly improves over several days as the tissues around the root settle. Tenderness can last longer when the tooth was infected or painful before treatment, but worsening pain, swelling, or a bite that feels high needs prompt review.

What is the direct answer?
What does this question mean?
A root canal removes inflamed or infected pulp from the chamber and canals inside a tooth. The canals are cleaned, shaped, disinfected, and sealed with a root-filling material, while the ligament and bone around the root can remain irritated for a period afterward.
What can you do next?
Take only pain medicine that is appropriate for you and follow the label or your dentist’s instructions. Chew on the other side until the permanent restoration is placed, keep the area clean, and contact the clinic if the tooth hits first when you bite.
When should you seek dental care?
Seek urgent dental care for increasing pain, facial swelling, fever, difficulty swallowing, or difficulty breathing. Contact the treating dentist if pain is not steadily improving, the temporary filling breaks, or the tooth cannot be used comfortably.
What should you ask the dentist?
Ask whether the tenderness is expected for your tooth, when the permanent crown or filling should be placed, and whether the bite needs adjustment. Ask what symptoms would indicate a persistent infection or a problem with the restoration.
