Our wisdom teeth were nature's version of a back-up system - giving us one last set of teeth that would come out by the age we would've destroyed our molars when we lived in the wild. Why are they called wisdom teeth? Hopefully, we would get them at the age when we were wise enough to take care of them properly, usually by our mid-teens. Unlike our relatives ten thousand years ago, our molars haven't fallen out yet, we hope. Because of this, crowding often occurs when wisdom teeth erupt, causing them to come in sideways. Cock-eyed teeth can't be cleaned and will destroy adjacent teeth - which is why they're often removed.
