I am NOT saying this is the reason the dental office is no longer working with that particular insurance carrier. I have no idea what the reason is.

I just want to point out there is another potential reason. It is possible that the insurance carrier has discontinued their relationship with the dentist. It happens. I know some health insurance carriers discontinue their relationship with MD's if there have been too many complaints/cases against a particular physician. I expect it happens with dentists as well.
