Ouch. Insurance. What a hassle. I hate to say this, but it was YOUR job to be sure that the procedure was covered before you had it. I'm sure there is a claims dispute procedure, and I suggest that you proceed with it along with the help of your dental office. They'll likely need to help you support that coverage is warranted.
I have had a case where the medical professional said everything was covered by insurance and no amounts were due and then a year later sent a bill to the patient for $1800. They backed off on that, and perhaps you can cut a deal with the dentist if the insurance claim doesn't pan out. Oftentimes insurance companies pay far less than private individuals, and I suggest you negotiate a reduced rate for the procedure. It's not clear how much is due or if you're able to pay, and those factors will play into what the dentist is willing to do.
Hopefully you'll be able to work out something fair to everyone. Be sure that next time you have any type of medical or dental procedure that you first confirm coverage with your insurer.
