I had a root canal on tooth days ago. Still taking strong pain pills and antibiotics. Dentist said he does not know anything else to do. Any suggestions?

First continue taking antibiotics, secondly if the root canal was completed you SHOULD NOT be having any pain at all. If your dentist does not know what else to do, you should search out another dentist that can help you. also if you are in that much pain that you need pain killers, something else could be going on. See another dentist as soon as you can, but stay on the antibiotics to be safe.
