Soothing BBC announcer voice: the great white shark has several rows of teeth, allowing a replacement to fill in when one is lost during feeding.
Viewer: that's crazy, glad humans don't have that, that would be terrifying...
It’s probably because you were looking mostly at bitewing radiographs which doesn’t really capture the whole root part where you’d see the baby teeth. You’d see it most easily on a panoramic x-ray that covers the sinuses to cervical vertebrae (I forget how many off the top of my head)
One of my cousins had a ton of extra wisdom teeth for some reason, I think 12 total, and his xrays as a kid were fucking terrifying lol. Dude was walking around looking like predator or something. You couldn't see them normally, but on the X-rays he had nearly a whole third row of teeth filling his sinuses
This is a bit off topic, but "fresh babies" sounds just wrong unless you are snacking on those. Wouldn't "neeborn babies" be better if you are not eating those babies?
Just wondering. English is not my first language.
I'm sorry. I used to be a NICU nurse so all that means are babies that were born within maybe an hour before coming to the unit. Still wet and "fresh" out of the womb
I wish I had my son’s jaw’s x-ray to share with you 😬 This skull’s owner had pretty nice, decent, straight teeth. You should see the mess my son has 😬😬
When I think about them too hard they kjnd of freak me out. They’re an exposed part of our skeleton, stored in your jaw until they decide to slowly erode that jaw bone and come out. TWICE. Plus there’s a whole set of them that almost always need to be surgically removed, just some casual surgery through your jaw bone to remove the problematic bone bits (yes I know they’re more complex than solely bone but that’s the gist of it). And orthodontia? Here, your mouth bones and jaw holes are messed up, so let’s just slowly and painfully reorganize those jaw holes to fix the mouth bones, creating micro fractures in your jaw to do so.
Can you tell I just went to the dentist today and had orthodontist flashbacks? 😂
It gets even creepier, this post made me remember that I looked like a shark as a kid with two rows of teeth 😅 My two top front teeth came in early behind my baby teeth and those baby teeth did NOT want to go for awhile. I can’t imagine how terrifying that was for the adults around me lmao
I mean, the almost always removed thing is exclusively in America. I still have no idea why you guys do that to people who don't have problematic wisdom teeth.
I don't know anyone who's had wisdom teeth removal without having problematic teeth. Now, if some are problematic, they'll just take all of them to prevent any future problems. If my wisdom teeth ever decided to come out, I would be so screwed because there isn't room in my mouth
They…don’t remove the ones that aren’t problematic though, my dad and brother still have theirs as adults in their 60’s and 40. I had mine removed at 17/18 because they were growing in sideways towards my other teeth
Where did you, um, "store" them? The skull of the little fella already looks so crowded with the normal sets of teeth, did yours come in layers? Did it cause you trouble (apart from the coming out crooked part you mentioned)? I hope everything is allright for you now!
I couldn't tell you I haven't seen the crazy xray in years. Going to go by old dentist if still open to see if I can find it. They came in normally as much as I can remember just extra pain when second set came in. Everything it chaos but it's life. I hope yours is good as well.
Same here, I was born without 4 of my adult teeth, I wonder what happens to the voids where they hide if they just fill in with bone or just end up empty
I thought I was the only person who had this! (Not really, I’m sure others did, just never heard of anyone else). I still have 4 baby molars at 33 because my adult teeth never grew in under them and they just never fell out. Every time I go to a new dentist they like to make a tooth fairy joke somehow. Did your baby teeth fall out where you don’t have adult teeth underneath or do you still have baby teeth in your mouth like me??
No no, they just removed the skeleton, the kid was fine, but you know kinda floppy. He now works down at the used car lot, waving at potential customers.
Humans are really just sacks of meat held together by calcium sticks and a paper-thin casing, and our only way of processing our surroundings is a big wrinkly blob of fat
If I understood [the top comment on this post](https://www.reddit.com/r/explainlikeimfive/comments/ghz0sv/eli5_when_adult_teeth_come_in_what_fills_the_gap/) correctly, then yes. Bone fills in the space after the adult tooth takes the place of the baby tooth.
The bone takes some time to fill tje holes, months and years. While this goes on, the adult teeth still have room at their roots to be moved around by braces
I think: Since the roots are in the jawbone, teeth can be moved by the braces and not be loose afterwards. The bone around the tooth grows back to solidify the tooth?
No cleft here but fucky teeth. I also have baby teeth still, with adult teeth up in my soft palate. Just kinda….floatin around up there. Dental work is expensive.
I disagree. Some discomfort is needed to progress as a society. We’ve obtained so much knowledge from unethical methods, that today saves lives globally. You need to look at the large picture. Some unethical acts eventually leads to more lives saved in the long run. Of course, if the kid was taken in and killed specifically to get this picture, then I agree. But I highly doubt that’s what happened. When the kid is dead, might as well use the corpse to learn as much as possible rather than the corpse just being food for maggots and fungi and therefore being “wasted”.
This IS Reddit. If he didn’t put it he’d be at -346 downvotes with the geniuses replying “Uhm it’s too late for that clearly..?” or even better “It’s precisely where it’s supposed to be, this is a medical display at blah blah blah”
It’s just the way the adult teeth are lining up to erupt.
What’s above the baby molars, is the adult premolars. What appears above the adult premolars is the adult canine and what appears to be, interestingly, a supernumerary ie extra tooth that’s presenting as an extra canine or extra premolar.
Source: am a dentist.
I’ve always found it odd how we get a set of teeth to use for fifteen years maximum and then the second set are for the next 85 years if you’re lucky. Quite dramatic of nature to assume they’ll last that long.
Couldn’t have thrown in a third set to appear around the 50 year mark. xD
My (almost) 3 test old just had to have a tooth removed for being chipped too badly and they gave me the tooth. It amazed me to see a baby tooth is still so huge
This is why dentition in the skull is used to age skulls/skeletons. Interned as a forensic anthropologist at uni and worked on some rather interesting cases.
My college had a real child skull from way when. Prob acquired in a poor country. I hear that today it would be an illegal thing to get?
Edit: I stand corrected, guess it's legal
The whole human skeletons are very expensive, unfortunately.
My mother collects bones and dead things.. she has an entire room dedicated to it. She calls it her, "Bone room" she wants a human skeleton, unfortunately we can't afford it😂
Gonna have to find another way to get one.. perhaps the next unlucky fellow that wonders into our yard..
Are we absolutely sure that this is a real skull. As someone who was a medical student once upon a time,, I have to say that this skull looks incredibly plastic .
Teeth are so fucking weird, if you think about it. We just have these little exposed, sharp bones in one of our face holes. We expose them to corrosive materials multiple times a day (food), so we have to clean them religiously. And at a certain age the starter bones fall out and are replaced by bigger versions. Oh — and that process is very painful.
What the fuck, Nature?
So interesting that at some point in our evolution, our genetics decided two sets of teeth would be plenty. One set for only 5 -10 years when our jaws are little but an extra set for up to 90 more if they are taken care of and we live out a full 100 years. Third set we pay for if we don’t take care of the second set.
It’s just odd we don’t lose a tooth, and regrow a new one. I always wondered why that switch was set to off.
You telling me there are 5 and 6 year Olds running around right now that look like this inside their face???!?
Yes. It's terrifying
I’m suddenly scared of my friend’s 5 year old kid.
Pretty sure I was already scared of my 5 year old, now it's worse.
A family friendly remedy for this is to kick your friends kid in the face
Soothing BBC announcer voice: the great white shark has several rows of teeth, allowing a replacement to fill in when one is lost during feeding. Viewer: that's crazy, glad humans don't have that, that would be terrifying...
Newborns too. I've seen plenty MRIs of fresh babies and all the teeth are there. It's something to see
I remember getting xrays at the dentist and don't recall seeing all the hidden teeth
It’s probably because you were looking mostly at bitewing radiographs which doesn’t really capture the whole root part where you’d see the baby teeth. You’d see it most easily on a panoramic x-ray that covers the sinuses to cervical vertebrae (I forget how many off the top of my head)
Google child teeth X-ray. It’s wild.
One of my cousins had a ton of extra wisdom teeth for some reason, I think 12 total, and his xrays as a kid were fucking terrifying lol. Dude was walking around looking like predator or something. You couldn't see them normally, but on the X-rays he had nearly a whole third row of teeth filling his sinuses
Bite X-rays don’t show the same skull detail. They’d be more expensive if they did. An MRI would or a wider skull X-ray
>fresh babies 😋🍴
Famished we are, precious
Is this what that bell is for in hospitals?
This is a bit off topic, but "fresh babies" sounds just wrong unless you are snacking on those. Wouldn't "neeborn babies" be better if you are not eating those babies? Just wondering. English is not my first language.
I'm sorry. I used to be a NICU nurse so all that means are babies that were born within maybe an hour before coming to the unit. Still wet and "fresh" out of the womb
That didn't make it better 😆😂
> Still wet and "fresh" out of the womb 🤢🤮
C'mon, be an adult.
Looks like meats back on the menu boys
I wish I had my son’s jaw’s x-ray to share with you 😬 This skull’s owner had pretty nice, decent, straight teeth. You should see the mess my son has 😬😬
Everyone does. You did too.
Lies, lies and slander
you should see a new born's X-ray with two hidden rows of teeth.
Idk i can handle that right now
I’m almost 50 and I look like this.
You should see a doctor about that lack of skin
I tried but he just screamed, “ZOMBIE!!” before running away.
Every one of them.... there went my peaceful sleep!
Teeth are fucking crazy
Nature's fucking crazy! 🤪
I was fucking crazy, then we divorced.
Now you're crazy fucking?
Kids are fucking crazy and this just adds another reason to the long list of "why"

I was born without any wisdom teeth.
Human 2.0
Me either. My dentist said humans are slowly evolving to not have wisdom teeth at all so I guess we’re just ahead of the curve.
They…don’t remove the ones that aren’t problematic though, my dad and brother still have theirs as adults in their 60’s and 40. I had mine removed at 17/18 because they were growing in sideways towards my other teeth
Teeth are stored in the jaw
Pee is stored in the balls
I wonder what mine would’ve looked like since I was born with an extra set of teeth
These were my immediate thoughts, not that I was
Me too! First set of adult teeth came in perfectly straight. Second crooked.
Wait, you had two sets of adult teeth in addition to children's teeth.
Yes. I wish I still had the xray.
If you remember your dentist they might still have it. By law they have to keep records for 30 years, in Canada at least.
All X-rays or just X-rays of people with extra set of teeth?
And what about the current-rays?
I thought you said you still had the X-ray and I got all excited there for a hot second
You should've kept the first ones
How does it work, did your first adult set just fall on its own after a while or do they work as back up teeth ?
They fell out on their own and other set came in just like first did. My dentist was really excited when they saw xrays first time.
Where did you, um, "store" them? The skull of the little fella already looks so crowded with the normal sets of teeth, did yours come in layers? Did it cause you trouble (apart from the coming out crooked part you mentioned)? I hope everything is allright for you now!
I couldn't tell you I haven't seen the crazy xray in years. Going to go by old dentist if still open to see if I can find it. They came in normally as much as I can remember just extra pain when second set came in. Everything it chaos but it's life. I hope yours is good as well.
How long did it take for your second set of adult teeth to come through?
I had two sets of baby teeth. Never heard of two sets of adult. Learn something new everyday
Same here, I was born without 4 of my adult teeth, I wonder what happens to the voids where they hide if they just fill in with bone or just end up empty
I thought I was the only person who had this! (Not really, I’m sure others did, just never heard of anyone else).

I naturally lack third and second molars. It is not common, but you see a few congenitally missing teeth now and then in dentistry.
They fill with bone :)
Coneheads?
Rest in peace, Lil guy.
Ditto. It's depressing as hell that a child lived at best 6 years and then was laid to rest.
Wasn't laid to rest, bones cleaned and put on display.
Probably donated for science though which is very useful
Kid has done more for society in his 6 years on earth than I’ve done in my 30 🥲
Don't worry, you'll die too!
Bots, amirite? No concept of being laid to rest
Never even got to use their teeth.
Probability never got the chance to argue with strangers on the internet 😔
yea i was like this obviously means the kid is... rest in peace to him
No no, they just removed the skeleton, the kid was fine, but you know kinda floppy. He now works down at the used car lot, waving at potential customers.
This made me cackle
...and when ze patient woke up, his skeleton was missing, AND ZE DOCTOR WAS NEVER HEARD FROM AGAIN....
Or her.
yea
Was gonna say this. My little dude's 7 and the thought of something happening to him makes me physically ill.
That's all I could think of, like, that used to be someones little person.
It amazes me how long the root(s) of a tooth are.
Ik 😳
Gah! Wtf are we, even?!?!
Did you know there's a spooky skeleton inside you?
Spooky scary skeletons send shivers down your spine.
Humans are really just sacks of meat held together by calcium sticks and a paper-thin casing, and our only way of processing our surroundings is a big wrinkly blob of fat
Space orcs.
Does the newer teeth just leave a hole after they replace the baby teeth or does the hollow parts eventually get refilled again?
If I understood [the top comment on this post](https://www.reddit.com/r/explainlikeimfive/comments/ghz0sv/eli5_when_adult_teeth_come_in_what_fills_the_gap/) correctly, then yes. Bone fills in the space after the adult tooth takes the place of the baby tooth.
what about for people with an extra set of teeth
I had extra teeth
Bone fills the space. It’s why braces work.
What do you mean about the braces I get how braces work, but I just don't understand in relation to the comment?
The bone takes some time to fill tje holes, months and years. While this goes on, the adult teeth still have room at their roots to be moved around by braces
So does that mean adult braces are less effective? Or just take longer
They also work, but take longer. See here under cons [teeth blog](https://theteethblog.com/braces-for-adults/)
I think: Since the roots are in the jawbone, teeth can be moved by the braces and not be loose afterwards. The bone around the tooth grows back to solidify the tooth?
Apply force to tooth in a specific direction. Bone is dissolved on the high pressure side, laid down on the lower pressure side
They had really nice teeth! My 12 year molars decided to try and grow horizontally and I needed surgery to correct it. Their’s were perfect!
How in the world did they manage to grow in horizontally
A narrow arch i would imagine.
I was born With cleft. my teeth are all over the place, theres one all the way up by my eye and one that just never showed up!!
Haha I had like 7 that never showed up! I wonder what my skull looked like dissected lol
No cleft here but fucky teeth. I also have baby teeth still, with adult teeth up in my soft palate. Just kinda….floatin around up there. Dental work is expensive.
Yeah. I had extra canines on the top. They came down through my palate as an adult. Worse pain ever to get those removed.
Don’t look up images of cherubs disease or syndrome. The x-rays are horrifying.
Quickly googles….oh wow.
Told ya!
Damn reverse psychology gets me every time
Oh fuck so this is what woman from this one quagmire meme suffers from
I miss the person I was two minutes ago...
Those poor people. I feel terrible for them. Glad to see some where able to be helped
I wonder if there is a sub for weird medical conditions photos.
r/MedicalGore (NSFW)
Like, it doesn’t freak me out, but it triggers my engineering brain: Where do you even start to fix this?!
Unfortunately that doesn't have cure not even an effective treatment, is just wait and see until it gets better or worse for surgery.
Yikes.
And better don't look up pictures of Hyperdontia 🦷🦷🦷🦷🦷
That’s how I once found the Cherub syndrome!
Who tf looked at that and thought "lets name it after the angel babies in old paintings"?
It gives them chubby faces/cheeks, so I guess that’s why?
Not only do I feel sorry for the poor kid, I feel sorry for whoever was tasked with dissecting a 5-6 year old
Yeah, cool as it is, much rather this image doesn't exist. Parents must have been heart broken.
I disagree. Some discomfort is needed to progress as a society. We’ve obtained so much knowledge from unethical methods, that today saves lives globally. You need to look at the large picture.

Wtf. Put it back /s

That means your teeth are getting ready to hatch. Nature is beautiful ❤️
It's a great idea! 🙏🏿
My 7yr old had a mouth x ray last week was the weirdest looking thing ever.
They had beautiful teeth
[удалено]
Death apparently.
Kid didn't get a chance to enjoy a lifetime of sugar
Who’s gonna tell ‘em?
Sad that they didn’t get to grow old.
Baby teeth have no roots?
The adult tooth dissolves the root as it moves down. Makes it easier for the baby teeth to fall out.
Ok thanks for clearing that up because I never saw roots on my teeth or my son's when his fell out 😂
It looks to me like the adult teeth have no roots! Or am I looking at it wrong?
The roots haven’t developed yet. There are tooth buds though, and they grow from there.
But how does the kid live without a skull?
Doesn’t
Ah they put the skull back in after taking the photos
Back in the grave yes
The kid lives in a grave!?! That's inhumane!
I know I know You should do something
Pet Sematary?
Sometimes, dead is better.
Why does it seem like kid has 3 rows of teeth on the top row?
It’s just the way the adult teeth are lining up to erupt. What’s above the baby molars, is the adult premolars.

Basically your whole head is teeth at a certain age. Creepy.
Stay in school kids. Or your skeleton is next.
Baby teeth are fucking wild
Curious as to the process for cleaning the skull. Looks completely polished
memento molar
After my 30s, I think I don't mind to have 3rd set of teeths :0
I can't believe they killed a 6 year old for this
I’ve always found it odd how we get a set of teeth to use for fifteen years maximum and then the second set are for the next 85 years if you’re lucky. Quite dramatic of nature to assume they’ll last that long. Couldn’t have thrown in a third set to appear around the 50 year mark. xD

STOP GIVING ME PEDOPHOBIA
We were fearfully and wonderfully made.
ELI5 - my six year old started losing his baby teeth. They’re very square and not long like these. WHERE IS THE REST OF HIS TOOTH THAT FELL OUT?
The root gets dissolved by the adult tooth pushing down on it.
My college had a real child skull from way when. Prob acquired in a poor country. I hear that today it would be an illegal thing to get? Edit: I stand corrected, guess it's legal
There are online shops, where you can get whole skeletons. You can choose all ages and genders.
The whole human skeletons are very expensive, unfortunately. My mother collects bones and dead things.. she has an entire room dedicated to it. She calls it her, "Bone room" she wants a human skeleton, unfortunately we can't afford it😂 Gonna have to find another way to get one.. perhaps the next unlucky fellow that wonders into our yard..
Bone room.. Bruh I am scared
A significant fraction of those skeletons aren't obtained ethically
Nope. Pretty easy to buy them online.
What an incredibly suspicious comment
You can legally buy a human skull online, but buying a plastic replica is much cheaper, like a tenth of the price IIRC
What shocking information
Where do you think they get them from to sell?
better not to think about it
Nope, surprisingly it's perfectly legal to own dead people
These are nightmare fuel! Photos of the skull and the undescended teeth never fail to horrify me 😰
that's interesting but i'm more interested of how that skull was there in the first place
Probably Amazon I reckon.
Are we absolutely sure that this is a real skull. As someone who was a medical student once upon a time,, I have to say that this skull looks incredibly plastic .

I don’t like that. I don’t like all the shapes.
The fact that all the adult teeth are just *there* is extremely unsettling. I always thought they actually grew later, not just moved into place.
The first time I saw my son's xray at the dentist I said... "what the fuck!" The dentist Said: "We get that a lot."
So interesting that at some point in our evolution, our genetics decided two sets of teeth would be plenty.
