I don't know all the circumstances, and I don't think I'm in a position to comment on the ethics of your situation.
I know you told me to get a new dentist - and I should have listened, but a patient is in a very vulnerable position. He always acted as if somehow it was my fault that I was in pain . He was pleasant and I felt uncomfortable complaining -but he really never listened to me. When I told him the dentures were crooked, he said it was my mouth - and that was not true. He ignored my comments and as I was not a dentist, I wasn't able to tell him what was wrong. It is my opinion that his arrangement with his new business superceded his professional duty to that of his patients- and maybe there also were others in similar positions. Maybe that's why he is now practicing in California instead of New York. I understand that you are not in a position to judge.
s made to feel it was my fault I )I have some advice for others. Don't pay in advance
