I no longer get excited about medical innovation because I know I'll never be able to afford to benefit from any of it. I'm lucky to have gotten vaccinated as a child while that was still legal for the poors

When I was a teenager it was announced that we would soon be able to stimulate the growth of brand new teeth, right in the mouth. I'm almost 50 and I need some new fuckin' teeth real soon.
its possible now but the world is pretty fucked. we can already reduce aging too and reverse it, we have cancer treatments that have near 100 percent success rates for many cancers, and many of these developments were only in recent years but when you watch how much gets done without making it into actual hospitals because of shitass companies and practices it makes you feel a little concerned if any of that will really have an impact, especially when everything is already burning anyway.....
There was a new development in japan less than a year ago. Downside is all your teeth fall out and all regrow
I'm sorry, I thought you said there was a downside.
You think teething and a soft food diet isn't a downside? Any time I have anything done that requires soft food, I'm craving solid food within like three days. It sucks.
It didn't sound like a big deal, but somehow you just instilled in me an existential dread of having no teeth to enjoy solid foods when craving some.
Well you can still cut it into small pieces for minimal chewing. Last time I couldn't have solid food at all.
Given the state of my teeth, I'm not far from that anyway.
Tooth fairy isn’t unionized.
She's ionized?
The problem is those new teeth were soft with no enamel. This could address that. Either way, no insurance will cover this and it will cost a fortune.
My teeth already have no enamel so I'm game.

If this is legit and dental industry doesn’t try to drown it in a bathtub I’ll be fucking shocked.

Our medical knowledge is shockingly rudimentary. Why we can't coax cells to do what they did anyway before is something we really need to understand to pretend to have any kind of medical knowledge. What passes for medicine is nothing more than 19th century++. See this, do that, body will heal. That's about it. I'm shocked every time I see someone in a wheelchair, how can we have LLMs and hallucinated movies but not understand how a few milligrams of organic matter organizes into nerves? etc etc etc
I am hoping that the absolutely bonkers computing power we are currently wasting on fart videos will be used to simulate matter in the future, here's to cheering on the AI crash!
we do have the ability to coax cells and even turn differenciated cells into pluripotent stem cells we've been able to for years the people who did it won a nobel peace prize
In reality, AI will help solve a lot of our medical ignorance. Not the goofball LLMs, but specialized AI algorithms specifically geared towards niche medical research and applications. Don't let GPT and Gemini sour the potential of some possibly game changing software.
The human body is an immensely complex system of chemical reactions.
And before you say "simulate it", we don't have nearly enough computational resources to do that. Simple reactions or chains of reactions, yes, but even a simple body process consists of multiple steps and a number of large, complex molecules.
This right here. We can definitely model how a single chemical effects cells, but what about multiple chemicals together. The reality is we are still very far from simulating something like the side effects from multiple interacting drugs at once.
We will likely discover some incredible insights when we do this though.
We have a pretty good idea how things work during development, it's tricking those cells into the same process as a fully-formed organism that's hard. Isolating and distributing the hormones in the right way. I think you're underselling the complexity and scale of biology. We can't just put a tiny camera and chemo-sensor inside a neuron and see what's going on in real time and synthesize up a hundred thousand copies.
That's my point, we'll simulate it.
How many times have I read this headline....
My only question is - when will it be available?
Every time you read it it's in a mouse or a petri dish.
I wish they would put that on the headline.
According to the article, they used human teeth from cadavers
There's a big difference between doing something in a lab and mass producing it for millions of people.
I bet the catch here is it could accidentally grow anywhere in the body as long as it mimics what our mouth has (saliva). Imagine growing enamel in our tongues or throat.
Doesn't matter without an anchor point
Hell yeah. I'm gonna overuse this shit and just have 2 gigantic teeth. One on the top and one on the bottom. No more flossing for me. Fuse those bad boys together. I'll have the smile of an N64 game character.
I think that's just called dentures
What could PAWSIBLY go wrong?
Settle down Mitch Hedberg.

Hopefully in the right place.
Congrats, you're now a narwhal
Narwhals, narwhals, swimming in the ocean
Causing a commotion 'cause they are so awesome
How long until the dental restoration industry lobbies it out to be banned, so they can keep selling their photoshop jobs of people smiling with new teeth alongside crowns and implants, all at an inflated price?
It already happens with nano-hydroxyapatite pastes. In Europe you find them at the supermarket for 5 euro, in USA you need a prescription and it's sold for $$$

"Dental enamel has a unique structure, which gives enamel its remarkable properties that protect our teeth throughout life against physical, chemical, and thermal insults," said lead author Dr. Abshar Hasan
This man doesn't just disapprove of people mistreating their teeth, he is personally insulted by it. A true dentist.
