Hi there! I'm 17 and I really need some advice on what treatment I should get for my teeth, how long it will take and how much would I be looking at on spending. I have inserted some photos down below. I had a retainer when I was 9 to help with my cross bite, but since then it has changed. My orthodontist wanted to take drastic measures to fix my teeth, including pulling out teeth and operating on the piece of skin between the upper lip and gum. Is there another way?
