Common questions
Why does the tooth hurt after treatment?
The tissues around the tooth react to the treatment. An ache when biting usually goes away in a few days.
Can I skip treatment if the pain went away?
Pain sometimes stops when the nerve dies. But the infection stays and can spread to the bone. It needs treatment.
