Rct teeth pain
Mild tenderness after root canal treatment can occur, but increasing pain, swelling, fever, or a high bite needs dental review.
The short answer
Tenderness after root canal treatment can occur while the tissues around the tooth settle, but increasing pain, swelling, fever, or a high bite needs dental review. Pain when biting can also mean the temporary filling or crown is making the tooth contact too early.
What happens during root canal treatment?
Root canal treatment removes inflamed or infected pulp from the pulp chamber and root canals, then cleans, shapes, and seals them. Soreness may come from the periodontal ligament around the root, while persistent symptoms can relate to reinfection, a crack, leakage, or an uneven bite.
How should you care for a tooth after root canal treatment?
Follow the treating dentist’s instructions, chew on the other side until the final restoration is placed, and keep the tooth clean with gentle brushing and interdental cleaning. Do not adjust a crown or place medication inside the tooth yourself; contact the clinic if the bite feels high or symptoms are worsening.
When does root canal pain need prompt dental care?
Arrange prompt dental care for worsening pain, facial or gum swelling, fever, drainage, difficulty opening the mouth, or trouble swallowing or breathing. A lost temporary filling, a fractured tooth, or pain that does not begin to settle also warrants an examination.
What should you ask about pain after root canal treatment?
Ask whether the tooth has an even bite, whether the canals and seal appear satisfactory on examination and imaging, and whether a crack or periodontal problem could explain the symptoms. Also ask when the permanent crown or other cuspal coverage should be completed.
Frequently asked questions
Can a root-treated tooth hurt when I chew?
Yes. The tissues around the root may be tender, but a high bite, crack, leakage, or continuing infection should be checked if pain persists or worsens.
What should I do if my face swells after treatment?
Contact a dentist promptly, especially if swelling is increasing or you have fever, trouble opening your mouth, swallowing, or breathing.
