I used to work for a very good Orthodontist so let me tell you what I know. First call around to different Dentist and ask them who they recommend. You'll start hearing 1 or 2 Orthodontist over and over again. That's a big sign that they are good! Second when you go to meet them ask to see their before and after pics. They should have a ton! And the after pics should be amazing! Pay attention to the before pics too. If the teeth weren't that bad in the before pics then what's so special about the afters? You want to see kids with horrible bites and teeth and then see beautiful results. Also in all the years I worked almost all kids need to be in braces for a year and 1/2 to 2 years. If they claim it will take less than a year or way beyond 2 years then that's a bad sign too. The Orthodontist should also be willing to use headgear, expandable retainers and rubber bands if needed. Not all kids need all of these things but most will at least need one of these if not more during sometime in their treatment.
Also you want the ortho to have a set fee instead of a pay as you go plan. So after the ortho looks at her child they will come up with a treatment plan and a bill. Braces cost around $4 to $5000. If they claim way less it's a scam. If they tell you they can't give you an exact amount and they tell you they will just bill you as you go through treatment that's bad! I'll explain it like this: If they have a set fee then they give you a bill of $4500 for the total treatment then that's it. It doesn't matter if they have to have extra xrays, lots of rubber band wear, 2 1/2 years of treatment instead of 2 years. The cost stays the same and you don't own them anymore. But if they do the bill as you go then say your kid needs an extra xray, you'll get another bill, say they break a bracket, you'll get another bill, say treatment goes for 2 1/2 years instead of 2, you'll get another bill. So instead of paying $4500 you end up paying $6000. So that's me two cents on the matter. Hope that helps!!
