I was thinking maybe wisdom teeth extraction.

Common, but a lot of people never get it. Either they didn't grow wisdom teeth at all, or they aren't pressing into the rest of the teeth in a way to cause a problem, or they lack dental insurance.

It's one of those super low-priority surgeries for most people. I'm very glad I got it done myself, though!

Also that would come from a different data source, since it's a surgery done on luxury bones as opposed to regular bones.
