Help! I had an injury to the gum on Thursday night. It hurt a lot a bleed and I could see the tooth under one of my crowns. I went to an emergency dentist on Friday cause I'm up at school and they took the crown that was causing the pain off, left the one in front of it. Now the gums in that area are whit. I'm not having pain at all with it since they took the crown off. What does that mean, is it healing and growing back or is something else wrong, I can still see some of the tooth under the front crown?
