The main contributing factor to the recent increase in malocclusion is widely considered to be due to a sharp reduction in chewing stress, especially during critical periods of craniofacial growth.[10][1] Experiments done on non-human subjects have shown that induced nasal blockages and/or dietary changes earlier in life lead to maladaptive morphological change in their jaws, intended to simulate what we are observing globally in human children.[4] Significant craniofacial changes due to diet have even been experimentally shown in pigs during development; researchers fed groups either a hard-consistency diet or a soft-consistency diet, for eight months in total.[11] Drastic differences in jaw and facial musculature, facial structure, and tooth-crowding were observed; researchers directly related the findings to what we are observing more in human populations.[11]
I recall also reading about people in Australia and some other places with diets consisting of harder food for developing babies/toodlers having better jaw/teeth ratios and straighter teeth despite no regular access to a dentist, which kind of corroborates the findings.
more like eating more processed food. and I mean like ‘gone through a cooking process’ kind of way. We do a lot more now than just burn our meat and eat veggies raw to get nutrients. we simply just don’t need to work our jaws so hard to get what we need
Oh mine got the memo. They lay peacefully, horizontally in my jaw, like little Saddam Husseins until they decided they wanted to visit other parts of my jaw and make friends along the way.
Average age is not average for those that reached adulthood. Most adults still lived to decent ages unless you select for very dire situations, like the Black Plague, or specific outbreaks of violence, etc.
That is true, but tooth get worse when you grow older. So to die younger means you’ll leave a nicer skull for archaeologists to find. The number 35 was arbitrarily chosen, but I now think your fact was slumbering in my mind when I chose that number.
im p sure it has to do with stuff being easier to eat. we dont have to work with our jaw to tear or crush difficult foods since everything is processed or we have tools to make it easy. our jaws are underused, so they develop to be smaller than theyre supposed to be, and our teeth get crowded
Before we cut our food in perfectly sized bites with utensils our ancestors used to do it by biting into large pieces of food with their front teeth. That would wear them down evenly to form a nice flat bite.
I wouldn’t be surprised if that’s the skeleton of someone who died way younger than we think as well.
Everyone who’s replied to you so far are wrong and speculating. The real issue is actually lack of nutrition and exercise for the mouth. We’re not growing our jaws out quite right while our teeth are coming in.
I’ll admit I don’t have a citation. I just remember it from a video about how this African dude had magnificent teeth because of the environment he grew up in.
Edit: Oh nice, you found a wiki page which validates my thing!
Why do our teeth grow in less perfectly now?
We eat soft, processed foods now. We used to graze and chew constantly, which helps the jaw grow properly.

so too much damn baby food?

if only my wisdom teeth got the memo :+:

Should we be giving our toddlers bones to chew on?
For real though, what about people who have gaps in their teeth? Did they have too much hard food?
because people with very bad teeth survive nowadays
Well, that mf didn’t survive either… He’s dead…
But he lived a long and happy life. He died at the ripe old age of 35

Our food is way softer so we don’t chew enough to maximise the growth of our maxillae and jaws.
So… You’re saying I should eat more bones and chew on trees.
Nuts and bones. Tree bark of the yew tree when you inevitably get indigestion.
Yew wood, wouldn’t you?
I think I’d read before that it was because most of our foods now are soft foods so our teeth/jaws are not as strong.
Sugar content of our food is one of the reasons I read before as well.

this also sounds like speculation.

We eat shitty food
