So that’s why they are so freaking sensitive!
New teeth horror just dropped.
I wonder if this was how sharks got their skin teeth
Holy crap. I’d heard of placoid scales but had no idea they were homologous to teeth. Thank you for sharing.
It’s just a cool piece of information that it’s impossible not to share.
That explains narwhals 🦄
Imagine. You’re a fish just swimming around. You have skin that senses like a humans teeth can sense…a larger creature comes and crunches you and your teeth skin with their gigantic boned armoured jaw.
And then remember the last time novacaine didn’t work when someone was drilling your teeth.
Makes logical sense, I like it!
It does?
It does to me, I read the headline and immediately agreed with it
Hmm. Something about it feels just wrong to me. I’m fairly sure, though, that it’s a gut feeling and nothing logical. Because teeth on the outside? Because sensory organs in teeth? IDK.
Your teeth have never hurt? Teeth have a lot of nerves, and I have never really understood their biological purpose.
It’s important to not destroy your teeth. For wild animals, that means starvation. Given that you can’t have nerves right in the enamel, it makes sense to have nerves lower down and make them very sensitive. I have the pet theory that we evolved to hate that teeth grinding sound for exactly the same reason.
If those nerves were vestigial, they really should have disappeared by now.
Like to discourage trying to eat gravel? There aren’t many thingals that would cause acute tooth damage.
For example. Bear in mind that each animal needs to figure that out on its own as it grows up. Have you heard about humans who are unable to feel pain? Very rare congenital condition. Doctors remove their baby teeth or else they will chew up their tongue and mouth. That’s the sort of thing you need to think about.
A number of animals, birds especially, swallow rocks to help them grind up food in their intestine.

We come from the sea.
