I have a 7 yr old daughter with underbite a little over a 1/2 from top teeth, our dentist is advising us to see a orthodontist for surgery to break her jaw, we are very concerned. I don t want my childs jaw broke, we went today and was told they would need to break her jaw, we thought we were going to possibly speak of having braces put on, what are the pros and cons if we decide to do this. I want more than 1 opinion on doing this.
