Can I fix one crooked tooth with veneers or other "quick" methods? I have very crooked front teeth & don't want braces.

Believe it or not, I've had braces. I had them as a teen and never really achieved straight teeth. Now, I look around and see everyone else with perfect smiles. I'm so self conscious of my very crooked, yellow front tooth especially. I'm getting married this year and hate smiling for photos. I feel my teeth are holding me back. I don't know if I can go through the trauma of having braces as an adult and not being happy when they come off. But if it's the best option for me, I'd like to know.
