Do you detest the dentist?

I had to go to the dentist today. I havent been in about five years. Needless to say it was a QUITE painful experience.
Why do dentists make you feel like a slob, always?
I brush my teeth every day, almost obsessively, but they made me feel like I hadn’t brushed in years, and like I gross and disgusting.
Do they do that so you will keep coming back because you dont want to feel like that again or something? I’m not a slob. I dont like feeling like one.
Does anyone else get this feeling from the dentist? Is this why most adults quit going?
