The third molars—the last of a group of teeth that grinds food into easy-to-swallow chunks—tend to be overcrowded in adult human mouths, and thus require yanking. But every other toothed mammal has room for their "wisdom teeth," and so did Neanderthals and other early hominids, says evolutionary biologist Leslea Hlusko of the University of California, Berkeley. So why have those teeth become such a pain for us?
Genetics play a role in the shape and size of your jaw, but how it develops also depends on how much chewing stress you put on it during your childhood years, Hlusko says. Because we cook our food rather than tear meat from the carcass, it's generally softer and easier to chew. As a result, over the generations our jaws have shrunk compared with those of our pre-agriculture ancestors, and so we can't comfortably accommodate three sets of molars.
There is some evidence that eating platefuls of raw carrots and other tubers as a kid might help your jaw grow large enough to hold wisdom teeth, but you're probably as well off crossing your fingers and hoping that you fall into the 15 percent of the population that never develops a set of third molars (and not one of the unlucky few who grow more than four). Of course, then you don't have an excuse to eat ice cream for a week.

I thought the reason we have problems with wisdom teeth is that we generally don't lose our adult teeth anymore. Wisdom teeth are the extra just-in-case i break my teeth and need more - kinda like how when sharks lose teeth they have extra rows behind to fill in the space. Since breaking your teeth was probably a lot more common, there was room in the mouth, but with all our perfect smiles now we have overcrowding.
I have all my wisdom teeth, and never had a problem.
Our jaw shape is defined by the fact we have adapted to walking upright, so we won't have the space in our jaws for as many teeth as other animals.
I was forced by overbearing parents and dishonest dentists to have asymptomatic non impacted wisdom teeth removed against my will. And suffered nerve damage and infection as a result. Now I have this big empty space in the back of my mouth that I wish was filled with beautiful teeth. Why are there braces and other techniques for correcting the orientation of other teeth but no one dose anything to correct wisdom teeth they just yank em out. To me this is like cutting off your toe because you might stub it.
