Can orthodontic treatment be reversed after filing in between teeth? (Photos)

I had treatment 2 years ago. I was wanting jaw surgery- ortho advised against and he said it was only a slight assymetry. During treatment teeth looked good, but started to get a gap between top front teeth (didn't mind). Face looked more balanced but then ortho narrowed my top and bottom teeth brining my teeth inwards more to close gap, and filed in between. My face is flatter, older and my tongue rests in a very weird place. I look very strange when talking, my bottom teeth are only visible.
