Wisdom teeth are an extra set of molars that come in between ages 17 and 25. The best thing to do is to have them removed when they first show up, but many people put this off and still have their wisdom teeth as older adults.

Genetically engineered to be perfect? Without the need for 'care' or health checks, immunity to disease, among other things, aren't wisdom teeth a part of the human condition? A trial all humans undergo?
