I have had braces in the past but I failed to wear my retainer. Needless to say, my teeth have shifted. I have a minor overbite that bothers me. I found a coupon i the Mercer County clipper so I visited a local orthodontist. So far it has been a fast, easy, convenient and inexpensive. Basically I need 9 trays/5 months. And I am currently on tray #4. My teeth are looking better but it still very soon in the process. So far so good though. No problems at all so far...
