I went to the dentist to get my two front teeth crowned 5 days ago. After 5 hours the nurse finished the crowns and did a horrible job. She wanted to re-do everything but I was already very upset. The following day I got my crowns re-done again. They looked better but I was still in pain after. I went home and that night I started bleeding. It is now day 5 and I can't eat do to the pain and sensitivity. I have a blister behind the crown with some swelling. Should I be concerned?! What do I do!
