Can a root canal still hurt
A root-filled tooth can hurt from healing tissues, a high bite, persistent infection, a missed canal, a crack, or another tooth.
The short answer
A root-filled tooth can hurt from healing tissues, a high bite, persistent infection, a missed canal, a crack, or another tooth. A dentist uses the examination findings to identify the cause.
What does pain from a root-filled tooth usually involve?
The clinical subject is root canal pain. Possible causes include periodontal ligament, bite, canal system, restoration. The appearance or symptom alone does not establish a diagnosis.
How can you avoid aggravating a painful root-filled tooth?
Do not chew heavily on it. Keep the area clean, record changes, and arrange the appropriate dental examination. Treatment is selected after the cause and anatomy are assessed.
When does pain after root canal treatment need prompt care?
Seek prompt care for worsening pain, swelling, fever, pus, or a persistent change. Emergency assessment is needed for difficulty breathing or swallowing.
What should you ask about ongoing pain after treatment?
Ask about bite, restoration, imaging, crack, and retreatment. Ask which examination, imaging, laboratory test, or treatment is appropriate and what follow-up is needed.
Frequently asked questions
Can this be diagnosed at home?
No. Different dental causes can look or feel similar, so examination is needed.
What determines treatment?
The findings from the history, clinical examination, and any indicated tests determine treatment.
