I wore braces from approx. 1994 - 1996, and they did indeed do the job they were suppose to do. Unfortunately in the years that followed I didn't quite wear my retainers the way that I should have. My bottom teeth are still nicely aligned (straight), but the gap between my upper front teeth that the braces were able to close has returned. Can I go back to wearing my retainers to correct the problem, or what can I do?:confused:
