I don't know if you're expressing a common misconception here, but a lot of Americans also think general anaesthetic is widely used for wisdom teeth removal, and it isn't. What is widely used is deep sedation, a combination of ketamine and benzos which keeps the patient calm and, the nice part, prevents any memories of the event from forming. It's maybe an extra hour of recovery, same-day procedure in either case.

Post-care is a few day's worth of entry-level painkillers unless the patient gets a dry socket. We use acetaminophen for post-treatment rather than paracetamol, since it's better (never understood the British obsession with that stuff, it's nasty business).

Anywhere else I would walk away from a terrible joke like that, but this is HN. I'm joking.
