When I was living in Europe and had my wisdom-tooth removed I only got a local anesthetic so I wouldn't feel the cutting. Recently I heard a friend of mine (here in the US) say she was given vicodin afterwards. To me that's just insane. Sure I was a little uncomfortable for half a day but I'm not going to take bloody opioids because of that. It might also be the case that people just don't ask for it as easily as in the US (I mean, it's much more common to hear Americas place food orders with a bunch of custom stuff, Europeans usually just order what's on the menu).
