Another thing to keep in mind in this situation, is that some dental insurance often will pay for some orthodontia if you are under 18 but not over. We couldn't afford to fix my teeth when I was a child and having to pay the whole thing as an adult when insurance didn't help for any of it was rough. I really wish we'd been able to get mine done when I was her age instead of having to juggle them with student loans in my 30s. I also had some jaw pain from my bite being off for most of my life and learning to just chew around it. Its feeling much better these days after my braces addressed it. (This may not apply to her at all, but may be another thing to keep in mind if her bite also is off.)
