Hun, go and get them checked and see what the situation is. And remember, just because you don't go to the dentist doesn't mean there are no fillings needed just that you don't know about them. Yes, the dentist can be very expensive, but I'll give you a tip - the longer you leave dental problems, the more expensive they get. Go now, work out a plan, and you never know, things might not be as bad as you think .
