Hi, my 6YO has his lower front incisor really tangling right now and has been for 3 days. We tried a few times to pull it out but he cried badly. The tooth has also collapsed but a bit of the gum is still attached to it making it bleed when we tried to pull. Poor boy is feeling so uncomfortable with a collapsed and tangling tooth but we just don't know what to do. Any advice? Can we leave it like this and will it come off eventually or do we need to see a dentist to get it out?
