I had a similar experience as Justin13. I had gone in for some tooth sensitivity since Gentle Dental was covered under our insurance. I too had to argue against the 'mandated' test over and above the free cleaning provided by insurance. I wasn't told it was a state policy, I was told it was a corporate policy of Gentle Dental. I refused the service.
Dr. Basey did do x-rays since I was experiencing sensitivity. He came back in and told me I would need a crown, to the tune of $996 of which I would have to pay $645. I wasn't completely comfortable with this so I said I would need to think about it. After going home, I became more uncomfortable. I went back two days later and asked for a copy of my file and x-rays. I was told that the x-ray taken wasn't clear enough and they'd have to take another one which I let them do. They then turned over my files reluctantly. I did my research and found another dentist in MWC with high reviews - Dr. Bob Utech. I went in to see him, he checked my teeth and told my I had absolutely nothing wrong and did not need a crown. I will be going to Dr. Bob from now on.
I'm not sure how Gentle Dental stays in business expect to scam those who have no other options under their insurance. I too will be filing an official complaint with the Board of Dentistry. Dental work is expensive enough when needed, no one deserves to be fraudently charged for unnecessary work.
