I had my wisdom teeth out in my late twenties! Well, three of them, but that's all they could find.
A check with the Google indicates that, indeed, that last one could have just been lurking around waiting to cause me misery later in life.
Still, as thoroughly as my teeth have been x-rayed not long back, you'd think someone would have expressed surprise at a wisdom tooth still lurking around, un-erupted.
