As someone who 5 or 6 years ago was not going to the dentist since the very idea of it gave me anxiety after having a particularly bad and damaging dentist experience as a kid. When I would to to the dentist I would have a fight or flight moment just sitting in the chair. (TLDR, I was told they were going to do one thing as a kid, but they purposefully lied to me and did something else thinking I would be less anxious about it happening... yeah that went swimmingly)
The only way I got over that was being able to talk to the Dentist that I was working with, having them explain step by step what they are doing, they check in regularly, etc etc. I finally feel mostly comfortable going, to this specific dentist. The idea of switching has me anxious.
The idea of a robot, while great maybe it could have less human error and all that. No... just, no.
