In addition to all the other arguments here (more chewing for bigger jaw development), I have another theory about tooth decay.

I think that pre-civilization humans did not eat much sweets past adolescence. This is because, as soon as a minor cavity starts developing, it hurts like hell to put anything sweet in your mouth. Sweet stuff was for children and adolescents, then we just stopped eating it.

You ever wonder when they show a tribe from G-d knows where that had barely any contact with our civilization, how come they've got perfect white teeth and they've got them all? Nothing crooked, nothing missing.

I think a big part of it is that once you have even a minor cavity, eating anything sweet hurts like hell, so people just don't eat sweet stuff when they're older and have lost their baby teeth.

Natural selection. If you got fucked up teeth out in the wild you are screwed. If you got fucked up teeth in civilization since the 1700s theyd just give you pig teeth or wooden teeth or whatever to get you chompin again.

This article seems to be part of the recent wave of content about orthotropics/mewing. I'm not sure why it seems to have picked up so much recently.

Orthotropics and mewing was widely discussed on incel communities and now that the prominence of these communities has grown, the topic is trickling to the mainstream.

If you haven't heard of orthotropics, it sounds a bit pseuodoscience-ey, but it attempts to solve the crooked teeth issue by enlargening the jaw rather than through braces. Thus far, I have to say that I think there's some truth to exerting a little pressure to my maxilla/mandible, and if anything I can breathe much better, which for me is a bigger win than getting straighter teeth.

Human teeth development changed sometime during the industrial revolution when women were expected to work outside the home and breastfeeding norms were shortened from 3-4 years to more like 1 year. Or that's at least one interesting hypothesis from someone looking at old skulls.

Do you have a reference for this school of thought?
