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.

[–] mihor@lemmy.ml 6 points 1 day ago (1 children)

Could be, there's a similar remedy to wisdom teeth growing sideways. Apparently the body needs some sort of a signal for direction, so if you chew on a stick (e.g. a pencil) for 10-15 minutes each day, they should reallign themselves.

[–] elucubra@sopuli.xyz 4 points 22 hours ago

You forgot the /s at the end of “fix your teeth by chewing on a pencil for 15 minutes a day”, right?

[–] archomrade@midwest.social 52 points 2 days ago (1 children)

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

yogurt is yummy 😋

Because he died at 21. With perfect teeth.

[–] vonxylofon@lemmy.world 38 points 1 day 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.

[–] vonxylofon@lemmy.world 1 points 15 hours ago* (last edited 15 hours ago)

Eh, I deal with a few British people on a daily basis. Still relevant.

Edit: typo

[–] Dyskolos@lemmy.zip 3 points 21 hours ago

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

[–] Zorsith@lemmy.blahaj.zone 46 points 2 days 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

[–] Sammy@lemmy.dbzer0.com 47 points 2 days ago (3 children)

Outbreeding? (Alien bussy)?

Inbreeding is what caused crooked teeth

Why do our teeth grow in less perfectly now?

[–] acosmichippo@lemmy.world 93 points 2 days ago* (last edited 2 days 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@lemmy.world 50 points 2 days 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 :+:

[–] boogetyboo@aussie.zone 37 points 2 days 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@lemmy.world 13 points 2 days 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.

because people with very bad teeth survive nowadays

[–] lemmydividebyzero@reddthat.com 71 points 2 days ago (1 children)

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

[–] abbadon420@lemm.ee 24 points 2 days ago (1 children)

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

[–] MotoAsh@lemmy.world 8 points 2 days ago (2 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.

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

[–] brillotti@lemmy.world 38 points 2 days ago* (last edited 2 days ago) (1 children)

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

[–] Empricorn@feddit.nl 15 points 2 days ago (2 children)

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

[–] theneverfox@pawb.social 1 points 22 hours ago

I eat the joints of bones - further up they tend to splinter and taste more chalky, but the joints are delicious and satisfying once you get past the ick factor. I thought even the cartilage was gross as a kid, but at some point instincts kicked in and my body told me it was a great idea. I knew marrow was nutritious and some people ate it, but I still don't find it that appealing - joint bones are one of the most satisfying things ever though, I highly recommend gnawing on the end of a chicken wing

Just because of your comment, I grabbed some tree bark to try... Cinnamon sticks. And holy shit, I just wanted to try it out, but I couldn't stop. It just splinters at first, but once you start grinding the flavor kicks in and it just melts - 10/10, it'd be easy to eat enough to make yourself sick, but I'm going to be trying this again

And FWIW, I've never had a cavity. I brush my teeth every morning but otherwise only if I feel I need to. I slightly cracked a tooth once, but my dentist was great and told me to use fluoride toothpaste and hold off on a crown - it's been a decade and it hasn't bothered me in years

Trust your body. Yes, gnaw on bones and tree bark - not all of it, your body knows what is edible and what isn't. If your instincts say "gnaw on this", and it's not made of plastic or metal, give it a try... If you take it slowly, what's the worst that can happen? Probably a tummy ache

[–] jabathekek@sopuli.xyz 16 points 2 days ago (1 children)

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

[–] SpaceNoodle@lemmy.world 5 points 2 days ago

Yew wood, wouldn't you?

[–] cannedtuna@lemmy.world 19 points 2 days 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@lemmy.world 12 points 2 days ago

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

agriculture and its consequences (maybe)

Discovering fire and its consequences (real)

[–] PhlubbaDubba@lemm.ee 8 points 2 days 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

[–] SkunkWorkz@lemmy.world 1 points 22 hours ago* (last edited 21 hours ago)

You get cavities from sugar not crooked teeth. It’s that our food has become softer over the last few thousand years. Our jaws don’t get enough exercise during their developmental years. So they don’t grow large enough for our teeth. It’s also why many people have impacting wisdom teeth.

[–] sus@programming.dev 4 points 1 day 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

[–] SkunkWorkz@lemmy.world 1 points 22 hours ago

Yeah. I remember a story about an anthropologist who went to a indigenous tribe, IIRC somewhere around the pacific, he took photos of everyone’s teeth. Everyone had straight teeth from the kids to the elderly. Then a generation later someone else did the same thing. Went to that tribe and took photos. Many kids had crooked teeth. The only thing that changed is that they adopted a Western diet.

Can’t remember the name of that anthropologist, though.
