The last 2 times I went under (for a complicated tooth extraction and the subsequent implant) they didn’t do the countdown, which surprised me because that was what I remembered most clearly from my lung surgery as a teen. They just asked me if I was comfortable, then said “Good, cause you’re about to get extra comfortable!” and we laughed, then I woke up. Maybe it was a dental surgeon thing? But I’ve also got a really good relationship with the dental techs and the anesthesiologist was a riot.
