Braces and dental work gone wrong. What can be done? (Photo)

I'm so unhappy with my orthodontists work. I was unhappy to begin with, because my center line has always been to the side. Because I got my teeth whitened after braces and my porcelain tooth doesn't match the others since time has passed. (not his fault, I know) &even though I wear my retainer, my teeth have protruded outward. My overbite was never fixed, it's only gotten worse. Also many of my gaps were never closed. I had braces for 5 years. What can be done? (I realize these pics are awful)
