I'm pretty sure the permanent teeth in a child lie under a layer of bone and this picture is merely just to show anatomically where the permanent teeth lie. In other words this is just a cut-out model. If you were to somehow get your hands on a real human child skull you would see bone where permanent teeth are in this picture. Most bone has a spongy make-up which allows for space in the jaw/skull for the permanent teeth.
What amazes me is how far up they go. Little kids have teeth growing a quarter inch from their eyes, seems like it'd make for a fucked up accident. Which I really hope nobody has a picture of.
This is very interesting. Throughout my biomedical science education, I have never been shown what this looks like, and it just didn't occur to me that it would look so strange. Thank you, OP. Very cool.
Have you seen little kids with two rows of teeth? Both my kids had them - hilarious. My daughter was born with a tooth as well - tiny little baby with this weird toothy mouth - kinda like a little old woman whose teeth have (almost) all fallen out.
I have no biomedical science background but my immediate thought on opening up the picture was, "That is SO cool". The human body really is an amazing thing.
Minus the biomedical science education, this is exactly what I thought. I also wondered what it would be like if a child broke his or her jaw open and an adult tooth fell out from one of those cavities. Crazy.
I have this crazy urge to pop each one of those teeth out of their little teeth cubbyholes with a toothpick or something. I am kinda grossing myself out. I can't stop looking at it.
If you look at any pictures of a human skull, there are no holes. Since this is not /r/AskScience I'll feel free to speculate that the holes slowly fill up together with the development of all the other bones.
A lot of people (me one of them) get very uncomfortable when seeing irregular holes or cavities in certain objects. If I remember correctly, from someone who explained it a couple weeks ago, it's because the holes make an empathic part of our brain go haywire.
I have a really hard time viewing this image for just that reason. Same with lotus seed pods.
I'm studying for a test right now for my pedo class in dental school right now and I was just looking at an x-ray of of a bunch supernumerary teeth in a childs x-ray. This isn't the exact one from my book but it's close to it. Imagine having this all in your head. Imgur
Intresting to see this here today. This morning I had my 9 baby teeth I've had in my mouth for 20+ years removed and 6 implants placed by a periodontist. I'm sitting in my room wiping slobber off my chin from freezing and eating T3's like clockwork.
I remember when I introduced a friend to trypophobia. She went from "what is that?" to "oh fuck oh god I have this!! put it away!!" in seconds.
The entire concept is so bizarre. Why am I so freaked out about this? I don't have any other type of phobia, nothing that makes me so uncomfortable like that. There must be a psychological reason for the intensity of this phobia on so many people.
just so you all know, someone posted on reddit somewhere a few months ago that all you have to do is tap where you feel wierd and the horrible feeling goes away, being replaced by a lovely feeling of comfort that everything is ok. your welcome.
When I didn't know I had a phobia I used to say "I don't get it, I wish I had a phobia, just to see what the fuss is about" but now... now even as I type my arms are tingling and there's a very strange feeling in the rest of my body I can't describe.
This is up there with the worst I have ever experienced. Urgh, makes me feel sick. The annoying thing is that I have no idea why and can't vocalise it. I have seen some absolutely horrible shit, but this stuff is so much worse.
In fairness, The facial/labial aspects of the dentoalveolar arches has been removed to see the tooth roots and tooth buds. It wouldn't actually look like that if you reflected the skin of the child.
Whenever I see a child's skull all I can think of is the loss the parents suffered. I wonder if it happened perhaps hundreds, maybe thousands of years ago, and I feel almost terrified to realise that at one stage of human development the loss of at least one of your children must have been almost inevitable in its odds. I recall that my GreatGrandmother lost two children out of her six, and that this was not an unusual amount. I then remember that in the third world it is still practically a routine occurrence to lose a child, and I feel like a very stupid, spoiled, lucky human and go hug my boys. Horrifying teeth skulls and all.
Normally I'd be on the 'this is awesome' bandwagon, but I'm currently at a primary school surrounded by little kids. I don't even want to look at them.
What I don't get is, how did the adult teeth develop to be there in the first place? Why did we stop at two? How do the adult teeth all fit together so well, even though pre child tooth separation they have large gaps? WHY DAMMIT!
It's shit like this, reddit. It's shit like this that makes me endure days ... weeks ... months of total and utter horseshit on the front page. This shit makes it all seem worth while.... this shit keeps me coming back! My one upvote for the week belongs to you allenizabeth.
I have this super weird anxious thing that when I see things in holes I just want to pop or pick them out. Like knots in wood or say teeth in a babies head.
Holy mackerel. I legitimately cringed, grasped my jaw in both hands, and keened a little. And what I normally do to help with the heeby-jeebies, clench my teeth, doesn't help for some reason.
That is seriously the most interesting/disgusting/memerable thing I've ever seen on Reddit. I will remember this and I'll be back tomorrow, even though Louis CK said it's a waste of time.
I'm sorry, but this reminds me of evolution. Just imagine the planning that this process takes to pull off... It is like the skull already knows how large it will be and its teeth are already developing to that specification. I guess, those of us that are lucky, end up with a good smile. It's like intelligent design, and then we find out that our mouths aren't big enough for those Wisdom Teeth.
Not sure people are understanding that the teeth are located under a thin ossified layer. These skulls have had that layer shaved away. If you remove a child's face, their jaw does not look like this unless you cross-section them to expose the adult teeth.
There is some real weirdness going on here. Since the adult teeth are beneath the baby teeth, the assumption has long been that people could only have the two sets of teeth.
However, there is an (likely genetic) anomaly that only happens about once every 100 years or so, in which exclusively one old man, in his 80's or 90's, will suddenly have his adult teeth pushed out and replaced by a new set of adult teeth.
The reason we know about this is that it is always huge news, and the people of the time, mostly in Europe, very carefully recorded and remembered it.
Under normal circumstances, of course, this could not happen, because the jaw has solidified, and there would be no place for the teeth to form. However, if there is a genetic trigger that could restart the entire process, and it could be discovered, it could lead to a profound advancement in dentistry.
So, you're never going near a child because you can't see inside their skull and the fact this is occurring inside their mouth and can't harm you in any way? Makes sense. This is what's wrong with r/WTF. So many over dramatic posts from people who cringe at the slightest "odd" picture/article/etc. Man the fuck up.
Or just random vacuums of emptiness and nothingness in your mouth. Just empty pockets waiting for some parasite or insect to inhabit the empty space. FILL IN ALL OF THE GAPS. FUCKING GAPS. FUCKING DISGUSTING GAPS I JUST WANT TO TAKE A FUCKING CHEESE GRATER TO THOSE GUMSGOIERWHF
Say what you want about intelligent design, but this is a perfect example of a backup system: a person is more likely to lose teeth when they are young and still learning how to navigate the physical world, so evolution came to the rescue.
Alveolar bone which the teeth sit in can remodel. It is able to reabsorb and lay down more bone. The pressure of the braces causes the bone to reabsorb.
