I guess our third molars are called
wisdom teeth because they show up in the back of our mouths so late. Supposedly, humans are wiser by our late teens and early 20s than when we were youngsters.

It can't be they carry accumulated knowledge because I had my upper-right one removed today and I don't feel any less wise. A filling of six years ago fell out of it and it wasn't in good enough shape to patch. In fact, was extracted piece by piece!
Local anesthetics are a miracle for modern dentistry! Regardless of what you may infer from TV news, we live in one of the best times in history.
