I've had braces for 5 years and haven't been to the orthodontist in 4 years. My brackets & wires have fallen off. What do I do?

First, you're not the first person that this type of situation has happened to.  Things happen!  I suggest that you ask your dentist which orthodontist you should go to (not the original orthodontist!). Then, make an appointment to see that doctor. Tell them what happened and explain that money was an issue and that you are embarrassed about your situation. Most likely that doctor's office will call the original orthodontist's office and see what needs to happen to get you back in treatment with the new doctor. Since you didn't finish your original treatment plan, it is very unlikely that you would need to pay the whole balance to the original orthodontist's office.  Since it's been four years, they may have simply written it off. It would be helpful, though, to the new orthodontist to have your original records. Sometimes it's best to just start fresh. Good luck!
