Monday morning I had a dr replace an old root canal and put on a crown. The X-ray also showed a small infection, so I've been on Amoxicillin. Prior to his work the tooth did not hurt at all. Since the work, I've been in a lot of pain, on a scale of 10, between 6-8, worse at night. I went back yesterday and he adjusted the bite but I'm still in high pain. Ibuprofen doesn't help. He says I need to wait it out but I need to sleep, I'm exhausted. Is this normal? Do dentists ever prescribe pain meds?
