The protruding mouth and gaping front teeth were the biggest problems, so I corrected them! The dentist recommended tooth extraction to correct the protruding mouth, but I didn't think it would be a good idea to pull out the raw teeth, so I just corrected them. It's been a while now, and I didn't wear a retainer, so the canine area is a bit wide open, but I think it's still fine. The device never fell off, and I'm satisfied that it was completed within the deadline! I think it's much better than a small hospital!
