Because he died at 21. With perfect teeth.

[–] vonxylofon 41 points 2 weeks ago (1 children)

My teeth emphatically didn't look like that at 21. More like someone used a shotgun to implant them to my mouth. I could be from Britain for all I care.

ironic that that meme is 70s-80s dated. most brits get far better dental care than the average US citizen, where our health insurance stops before it covers our goddamned mouth bones.

[–] [email protected] 3 points 2 weeks ago

Isn't basically everyone getting better than the US? Except having a great military ofc.

Because apparently some of us only eat peanut butter and never chew anything solid

yogurt is yummy 😋

[–] [email protected] 50 points 2 weeks ago

Survivorship bias? Bodies that are in the right condition dry out and pull the teeth deeper set into jaw bones as part of decomposition, whereas otherwise the skeleton would not be intact?

I don't think inbreeding is going to solve this

[–] [email protected] 50 points 2 weeks ago (3 children)

Outbreeding? (Alien bussy)?

According to porn hub, plenty of people are committed to trying.

Inbreeding is what caused crooked teeth

Look at the inbred dogs and cats, not hard to understand

the original comment is a joke, you didn't need to clarify

only one way to find out

Why do our teeth grow in less perfectly now?

[–] acosmichippo 95 points 2 weeks ago* (last edited 2 weeks ago) (3 children)

https://en.wikipedia.org/wiki/Human_jaw_shrinkage

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]

so too much damn baby food?

[–] Caesium 51 points 2 weeks ago (1 children)

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

if only my wisdom teeth got the memo :+:

[–] [email protected] 37 points 2 weeks ago

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.

[–] ChapulinColorado 13 points 2 weeks ago

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.

[–] Anticorp 3 points 2 weeks ago* (last edited 2 weeks ago)

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?

[–] ajikeshi 77 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

because people with very bad teeth survive nowadays

[–] [email protected] 72 points 2 weeks ago (1 children)

Well, that mf didn't survive either... He's dead....

[–] [email protected] 24 points 2 weeks ago (1 children)

But he lived a long and happy life. He died at the ripe old age of 35

[–] MotoAsh 8 points 2 weeks ago (1 children)

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.

[–] [email protected] 2 points 2 weeks ago (1 children)

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.

Our food is way softer so we don't chew enough to maximise the growth of our maxillae and jaws.

[–] [email protected] 15 points 2 weeks ago (2 children)

So... You're saying I should eat more bones and chew on trees.

[–] [email protected] 16 points 2 weeks ago (1 children)

Nuts and bones. Tree bark of the yew tree when you inevitably get indigestion.

[–] SpaceNoodle 5 points 2 weeks ago

Yew wood, wouldn't you?

We eat soft, processed foods now. We used to graze and chew constantly, which helps the jaw grow properly.

[–] cannedtuna 19 points 2 weeks ago

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.

[–] smokin_shinobi 12 points 2 weeks ago

Sugar content of our food is one of the reasons I read before as well.

[–] DaddleDew 5 points 2 weeks ago* (last edited 2 weeks ago)

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.

[–] Mango 5 points 2 weeks ago (1 children)

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.

[–] acosmichippo 12 points 2 weeks ago (1 children)

this also sounds like speculation.

[–] Mango 2 points 2 weeks ago* (last edited 2 weeks ago)

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!

My dentist said that it's because we don't chew much. We just eat a lot of soft stuff which somehow negativity affects teeth such that they don't grow properly.

agriculture and its consequences (maybe)

[–] [email protected] 8 points 2 weeks ago (2 children)

Kinda? Humans consume a lot more sugar than they did 10,000 years ago, in addition to other foodstuff that are terrible for your teeth

[–] [email protected] 3 points 2 weeks ago (1 children)

The one I was thinking of is the (hypothesized) reduction in jaw size due to less need for powerful chewing, while teeth stayed the same size leading to many problems
