I have a hole in my tooth and I have for a long while now and it's just starting to get worse tomorrow I am going to the dentist but a bit after I got the hole in my tooth there has been a bad smell from the hole in my tooth and just 2 days ago my tooth has got to the point where it's hurting constantly I can't eat properly touch it brush my teeth or shut my mouth properly with out it hurting, anyone know what that could be?
