My 7yo DD has a slight underbite and her top permanent teeth have just come through. I am keen for her to start orthodontist treatment now, to avoid tooth extraction or surgery later on. Our dentist referred her on the NHS but we have been waiting for over 6 months and I think it would be worth it to see someone privately. I have heard about orthotropics and it would seem like a good option for her. Has anybody tried that? Can you recommend an orthodontist that does it? We are in SW London. Thanks!
