Call an orthodontist or two in your area and ask them who they recommend as dentists. Then call those dentists and ask them if they take your insurance. If they don't then ask them who they recommend.
Most dental insurance is mediocre I've found, except for ours, United Health. (We had a few different companies over the years.) It costs us about $700 a year for our family, but it's definitely worth it because everything is paid for except for 20% and we are entitled to two cleanings a year each. We see a prosthodontist (who is also a dentist) and that way we have everything covered if we need caps, crowns, and fillings. Prosthodontists have extra training to work on teeth. They're excellent. See if you can find a prosthodontist under your plan (try calling your insurance company and asking) and call and ask if he/she covers regular dental work along with prosthodontics. Usually they do.
Good luck!
