Is there any way to fix my bottom teeth to allow my top teeth to show when I smile? (photos)

My top teeth used to show before I had braces and, through some complications, they caused my bottom teeth to be pulled up and now my top teeth don't show at all. I have a permanent bridge on top and would like them to show, but even when I force my upper lip, I still can't see my top teeth. Is there any way to push the bottom teeth down to make room for my upper teeth to show?
