How long should toothache last after a root canal?
Tenderness after root canal treatment should gradually settle, but persistent, worsening or returning pain needs examination of the tooth and its bite.
Why can the tissues around a treated root remain tender?
The tissues around the root may remain tender after cleaning because they were inflamed and handled during treatment. A high temporary filling can also hurt on biting.
What can help while toothache settles after treatment?
Use the supplied pain plan, avoid chewing hard foods on the tooth until restored, and keep the temporary filling clean.
When does pain after a root canal need dental review?
Contact the treating dentist for worsening, throbbing or bite-triggered pain, or pain that returns after improving.
What should you ask about pain after root canal treatment?
Facial swelling, fever, difficulty swallowing or a lost temporary filling needs prompt dental care.
Frequently asked questions
Could another condition cause this?
The tissues around the root may remain tender after cleaning because they were inflamed and handled during treatment. A high temporary filling can also hurt on biting.
What should the dentist check?
Ask whether symptoms reflect healing, a high bite, leakage, a crack, a missed canal or infection beyond the root.
