Veneers before or after wisdom teeth extraction?

When I was 15 I had braces put on, and 3 months later my front R tooth went gray. The dentist told me that I must of had an injury when I was younger, and when the braces moved the tooth, it couldn't take the blood cut off. I then had a root canal. I desperately need a veneer on that tooth, and preferably on all my teeth. My wisdom teeth arent in. I hear that the wisdom teeth move your teeth so should I wait to get my veneers until after my wisdom teeth come and go, maybe even years from now?
