The pace of our lives are closely intertwined with so many things: hormonal changes, literal growing pains, and (of course) dental development. Most of us don\u2019t remember teething, but plenty recall having our wisdom teeth erupt and, if you live in a place that regularly removes them, getting them yanked out of your jaw. It\u2019s just one dental milestone and one of three molar milestones, but until recently we had no idea why wisdom teeth emerged so late in life.<\/p>\n
A 2021 study in Science Advances<\/em><\/a> suggests a reason: our jaws are simply late bloomers.<\/p>\n \u201cIt turns out that our jaws grow very slowly, likely due to our overall slow life histories and, in combination with our short faces, delays when a mechanically safe space\u2014or a \u2018sweet spot,\u2019 if you will\u2014is available, resulting in our very late ages at molar emergence,\u201d said Gary Schwartz, a paleoanthropologist at the Institute of Human Origins at Arizona State University, who co-authored the paper, in a press release<\/a>. It\u2019s easy to forget that our teeth undergo quite a bit of mechanical pressure as they chomp down on food, as does your entire jaw structure. And that means your jaw needs to be developmentally ready to have teeth all the way at the back of our mouths nearest the joint. If wisdom teeth emerged earlier, the molars could actually damage the jaw they\u2019re growing out of.<\/p>\n All of this is the result of two fundamental things about humans: we have prolonged lives and short faces. Life, short as it may seem, is pretty stretched out for humans in comparison with other creatures, even other primates. We develop slowly\u2014we take our time\u2014and we spend an inordinately long period just becoming adults. And, unlike our primate cousins, our faces are quite flat and squashed. Just take a look at chimpanzees or gorillas; you\u2019ll notice that their jaws protrude outwards such that their mouths are mostly in front of their brain (though you probably never thought of it that way). Our faces are pulled in, sitting beneath our braincase.<\/p>\n The combination of these factors means that our jaws can\u2019t accommodate that final set of molars until fairly late in life.<\/p>\n Lots of people in the US get their wisdom teeth taken out, which might make you think that they\u2019re some kind of evolutionary leftover\u2014some artifact of a prehistoric life that\u2019s no longer relevant. But the truth is that you don\u2019t necessarily need to get them removed. In the UK, for instance, wisdom teeth are only removed if they become problematic, as the National Health Service notes that there is otherwise no proven benefit<\/a> (but there is the added complication of having a minor surgery).<\/p>\n Either way, the teeth are not so much a leftover as they are a sign of our evolutionary progress. Our squashy faces and slow development are part of what makes us human, weird dental development and all.<\/p>\n","protected":false},"excerpt":{"rendered":" Wisdom teeth are often painful, but they often don’t need to be removed.
