I went in for a dental cleaning a couple years ago and the young technician said I had the cleanest teeth he'd ever worked on. He was genuinely impressed with my dental hygiene, said he almost didn't need to do anything for my appointment.

I have a bad habit of forgetting to brush regularly (thanks, ADHD!), so I do it sporadically when I remember. As such, I typically have a cavity or two when I come in for my annual checkup. I had also just brushed and flossed right before that cleaning appointment; I did nothing else.

Also, this kid was really young. Like, barely 18 young. He had printed out a bunch of positive reviews from other dental patients he had cleaned, and taped them on the wall in front of the dentist chair. It was a little cringey.
