Oh my, I was going to say most dental plans cost far more than they ever pay out, not so much if you are talking about general anesthesia.
I could go to work tomorrow and ask what we charge but that would be what you would pay for out of pocket in St Louis, ya know? I know most doctors take payment plans.
Your best bet is to find a dentist, then find out what anesthesia group they work with and contact them directly.
