I've had braces 7 years ago, never had my wisdom teeth out. Both my top and bottom teeth are flared/angled out and I really want to fix my teeth. I can't smile comfortably and I'm hesitant to smile sometimes because of my teeth. My bottom teeth are crooked. I also don't like the shapes particularly the top front 4 and bottom 4 teeth. I would like straight teeth and for my front 2 "buck" teeth to be shaped "skinnier". I'm 24 year old. What are the steps I should take? How long will it take?
