one of the worst decisions I ever made

If you want straight teeth go to an orthodontist. Ask yourself, what if clear braces they don't straighten your teeth correctly- a dentist can do nothing but say, "that is what the tray does". An ortho can make an adjustment. I was told 6 months, I'm into 2 years. My teeth are straight, but my ability to bit all the way down is gone. All they say is we can do more trays. A dentist is a dentist and an orthodontist is an orthodontist. Any dentist can win you over and say all the right things. Just apply common sense to your ortho needs.
