Hello. I had a root canal done with a crown placed 10 years ago. Everything was fine, until a month ago. I started having a dull pain on pressure, when I chew, even soft food. Also, the pain radiated to my ear and mandibular. I thought I should not have any pain, since the nerve is not there anymore, but probably I have an infection and infection causes this pain. Are there any options in my case to safe the hurting tooth besides pulling it out. If yes, what can be done? Thank you very much for your consultation.
