What would you suggest to fix my very uneven smile? (photo)

My smile has always had so many imperfections. I had crowding on both the top and bottom rows of my teeth. I had one tooth removed from the top which made my smile very off centered. I also had one tooth extracted from the bottom. I had braces on for four years and this is the best they could do. Even the dentist told me everything from my bite to my crooked jaw was odd. My smile is also very asymmetrical with my left side being more dominant than my right.
