Exactly my experience. I had one great dentist as a kid. After college I moved to far to see him, so I called up his office to ask the stupid question. Same woman was his office manager since the 90s. She remembered me from when I was a kid. I asked to talk to him. Didn't think it would work but she grabbed him. Turned out I was lucky. He was only in two days a week by then. Turning the practice over to his daughter.

Anyways: he told me to find someone who ran a practice and was a Master of the Academy of General Dentistry (or at least a Fellow)[1]. He was a MAGD and insisted his daughter earned FAGD before he'd turn over his practice. So grain of salt. Ever since then I only used one dentist that wasn't one with immediate regret.

My new dentist office is run by a FAGD. It's fine. I just have to say no to flouride every time.
