Ok, we know it's messed up. But, the question is how can we do better?

https://www.usatoday.com/story/news/nation/2014/01/06/tooth-... Scientists examined the remains of 52 adults who had lived between roughly 12,000 and 13,000 B.C. and were buried in the cave. An astonishing 49 of them, or 94%, had cavities, which affected more than half of the surviving teeth.
Are you trying to imply that refined sugars do not cause an increase in tooth decay? Or that fruit sugar is similar to refined sugars? Any ties with the sugar lobbby famous for lobbying the US government into blackmailing the WHO in increasing the amounts “healthy” sugar in their dietary guidelines?
"Refined sugar" is sugar in fruit. It is literally the same thing. That's how we get sugar in the first place - from plants. You are dealing with glucose, fructose, and sucrose in both cases.

It’s because the story sounds like bullshit. I have no doubt that you can tell the age of a skull with a close inspection of the teeth. This story was an anthropologist looking at remains from several feet away and claiming that it’s aboriginal from the lack of dental decay. I proposed a few exceptions to that rule. Certainly not a quip about the expertise of the anthropologist, but rather the accuracy of the story.
I agree it sounds like bullshit. However, I have listened to a talk by a lady (she consults on murdered cadavers) who can tell which season a body died in by analyzing the teeth! Apparently there is a lot there.
That I can believe, assuming a detailed analysis in a lab. But snap judging from a distance? Cavities are more common in modern populations than before, but hardly omnipresent. I do find it an amusing thought that apparently my skeleton would be assigned a more distant past simply because I am filling free. :D

#175Weston Price talked a lot about this https://www.westonaprice.org/health-topics/traditional-diets...
I highly recommend reviewing Prices account of his studies in the field: http://gutenberg.net.au/ebooks02/0200251h.html
His conclusion was quite different: that the cause was a lack of nutrients in the modern diet.
It is difficult to point to an example from his work that would clearly rule out the theory of chewing in this article. Sugar and white flour that he pointed to are both easy to chew and low in nutrients.
However, it is hard to think of lack of chewing as the primary factor in tooth decay, and Price was focused first on decay rather than crowding. Price did note a very strong relation between decay and crowding, and in that light it is difficult to view lack of chewing as the primary force in either decay or crowding.

Don't you start losing bone mass once the teeth are out?
Only if you don’t get implants, a bridge or dentures. It’s not about the teeth per se, it’s about the pressure you exert on the bone underneath the teeth. If you can still bite hard and exert force on the underlying bone you’ll be fine.
What a horrible design.

For those of us that don't know (myself included), what is "mewing"?
Exerting pressure on your palate with your tongue, which stimulates growth in the jaw and acts on the maxilla, shifting it forward and up over time.

I’d love to see some actual evidence of that, which isn’t in the form of online anecdotes and testimonials on sites dedicated to the concept, or weird-as-hell “incel” sites. Something peer reviewed, in a respected journal would be a stsrt, even if the results haven’t been replicated yet.
Because it sounds like complete nonsense, and looking at the sites discussing it only reinforces my belief that it’s crap. I’ve spent some time searching for even a scrap of what someone with a hint of skepticism would consider compelling evidence and found nothing. I did find some communities I never knew existed, and wish I could now forget. Suffice it to say that “incels” are a truly strange bunch, and gullible at that.

> Doesn’t seem like a great way to tell the age of a skull. Going to take a guess and say that a brief glance at the teeth is probably not the _only_ age determination method they applied before determining their course of action.
and asked her how she could tell even from afar that these were not more current remains
Right, and then after making that initial assessment, I'm going to guess they didn't just stop walking, write out and sign the incident report and pull out the radio to let the station know that they were pretty much done here and there's nothing to worry about. No, I assume they walked up to it and got a more conclusive look at the body first.

#180I think the argument of orthotropics[0], bad tongue posture, is much more convincing.
