If you're also not happy with your teeth then you could get invisalign, which are clear aligners (retainers) that slide over your teeth and that you have to remove in order to eat or drink anything other than water. You have to wear the aligners for 22 hours each day so you can't snack throughout the day as many people do. I lost 25 pounds in my first three months on invisalign. It's possible to gain the weight back as you learn to adapt :) but it's a useful lesson in how to eat less.
