> For those living on a hunter-gatherer diet, overbites in the jaws and teeth in youth were often replaced in adulthood by what are called edge-to-edge bites, where front teeth sit atop one another. But with a softer diet, overbites may persist into adulthood. This post from the other day goes into that aspect in more depth: > Why Are Human Teeth So Messed Up?
