I have a post...at least that is what I think it is called. The tooth has a long post on it. I've had it for almost two years I think. It came out this week. I put it back in. It is loose, but will not come out unless I chew gum. I was going to wait until I could go to the dentist. I woke up this morning and my whole right side of my face and lip was swollen. My dentist is closed today. What should I do?
