Gummy smile and incompetent lip/chin strain exacerbated after braces. Can tooth/jaw changes be reversed?

I got damon braces to improve incompetent lips, strained chin, gummy smile. Three years and US$6k later, all three issues are exacerbated, not to mention my looks in general dis-improved. I am still in braces. Is it possible for the orthodontist to backtrack the treatment to try and ameliorate the situation? Do I have any recourse with the ortho? I wish I had never gone for the treatment. I am very upset and discontent with my appearance. Thanks for everybody's help!
