I had braces to fix my overbite 15 years ago and I did't wear a retainer properly. I know for years that my upper teeth have been constantly shifting outward but just recently that this really bothers me. I went to see an orthodontist and she said that I couldn't do a second braces due to limited space I have left between my teeth and also I already had 4 teeth extraction. What are your opinions? If I can't get braces again, is there other way to fix my buck teeth to look less prominent?
