That's freaking nuts. Xrays and deep cleanings are covered by my insurance. I had an extraction and a couple of root canals but they were definitely necessary.I had a "sky is falling" dental appointment a few years ago. It was a private practice. They also said I needed a deep cleaning, but first a prescription mouthwash. And they took x-rays that were over the top and not covered by my insurance. When the second appointment was close, they called to remind me and told me that the cleaning would cost $150 (I think). I cancelled the appointment, and went elsewhere. I never got a bill for those x-rays.
