Creepy male dentist

I’ve been “assigned” to a new dentist recently.

To put it bluntly, he gives me the fucking creeps, but I have no idea why.

Because he gives me the creeps, I’ve scrutinized his behavior, and there is absolutely nothing I can point to that seems unprofessional. All of his physical actions have been above-board. There is always a dental assistant in the room with us, so I’m never left alone with him. He has never sexually harassed me or said anything untoward. He has never looked at me inappropriately.

But he gives me the creeps.

I’m not looking for advice per se. I’d love to hear your ideas on why he would seem creepy when he has done nothing wrong. Have any of you had a similar experience with a medical professional?

And yes, I am listening to my gut. Eventually, I will find another dentist.
