I am in SEVERE pain! I went to the dentist and he said I have an absceeed tooth that needs a root canal. He prescribed amoxicillan and metronidazole as well as tylenol#3. I am taking these as prescribed, yet am still in agonizing pain. The pain seems to subside for maybe 5 minutes, but then comes back in waves, that shoot pain up to my ear and all through my cheek. I have a root canal scheduled for a month from now, since the infection apparently needs to lessen before they can fix the tooth. Any suggestions on how to make the pain stop? or at least be more bearable? Should I get a second opinion?
