What procedure can fix my four front teeth of uneven length and does little/no damage to original teeth? (Photos)

My orthodontist chose to file down my right front tooth because of a small chip and the one next to it. She also proceeded to file the two front teeth on the left. I really want the original length of my front four teeth back. I have been self-conscious about this for 4 years now. What procedure should I get? I want a procedure with no or minimal enamel removal. Will I be ruining my healthy teeth in long run? Also my smile is extremely uneven as seen from the shape of my lips, how to fix this?
