A bit of a positive thinking here: maybe it's the same research and they keep making progress.
Most of my teeth are destroyed, decades of neglect due to mental illness. I've been hearing about lab-grown teeth for the last 25 years and always hope it happens soon, but the progress sees to be genuine this time. I just hope it doesn't cost insane amounts of money to get teefs grown.
I'm pretty much in the same position, my poor dentist is doing what he can to help whats left of mine, but 45 years of neglect due to mental illness has taken it's toll, I wish implants were cheap enough but not sure if could afford them :o(
My family have been really great at helping to encourage me to start overcoming many of my issues last few years, is slow progress through, they got me out of house today and took me shopping... lol...feel tired and worn out, but at least got out of house for once :o)
I hope that you are doing okay, your not alone, so many of us in same boat, you are a part of our 'family' and you are loved, wanted, needed and valued, thank you for being you huuuuugs :o)
Schizo here, didn't brush for 10 years after psychosis. Cost me much when finally i succumbed to pain from a bad one and got to a dentist. I don't know if there's any teeth in my mouth that haven't had some drill action
I'm so sorry you went through this, I hope that you are in a better place now, mental health is one of the worst things that can happen to us, you are one of our 'family' who is loved and needed too huuuuugs :o)
Can't wait for the stories about how the fillings are tuned for the new 8G networks and caused COVID-29.
If lab grown teeth give me better reception then I'm all for it!
Yeah but you have an unskippable 30-second ad whenever you wake up.

So are you a writer for Black Mirror or a time traveler or...?
We should all gulp.... Could this research benefit non US people only?
Insurance is guaranteed not to cover this.

Luxury bones!
And boy it sounds expensive.
I've been hearing about lab grown teeth for decades at this point. Cool to hear progress regardless though
They're going to need to shrink it down, that's way too big.
Seriously, that's never going to fit. Idiots.
I have no doubt that this is a good thing and will improve quality of life, however just the concept itself is the stuff of nightmares.
Teeth…just there….growing….
Honestly, a number of animals have regenerating teeth. Many animals in the past (like dinosaurs) also had regenerating teeth.
Humans are missing out.
Yeah, thanks, I'll prefer the ceramic implant. Which works fine already.
That's great but how would it connect itself to the nervous system?
Step one is to let it relax so you're dealing with a calm system instead.
oh my
We have different ideas to put the teeth inside the mouth. We could transplant the young tooth cells at the location of the missing tooth and let them grow inside mouth. Alternatively, we could create the whole tooth in the lab before placing it in the patient’s mouth.
I assume option 1 at least would lead to the nerve connections naturally growing as the tooth does. Regardless, this still seems in the super early lab-proof-of-concept stage so I guess the ultimate answer is we don't know yet.
Hmm, option 2 seems like root canal treatment but instead there is a new tooth. However if they can predict the direction where the tooth will grow, option 1 seems promising.
Has anyone with a 3d printer tried 3d dentures yet? Would that work?
Nope. As far as extrusion printing goes: normal 3D printing filament is not food safe and the tiny stairstep layers would be perfect breeding grounds for bacteria and plaque impossible to properly clean. For resin printing: that shit's toxic in liquid form, very bad idea to ingest as a solid, and dust from the hardened prints (like if you sand a nub down) when breathed in works like asbestos on your lungs.
Dental printers are a pretty standard way to make these things. There's a whole regulatory process for testing and certifying the printers and their resins for continued contact with gums/skin/teeth for toxicity, infection, irritation, etc.
But there are still significant drawbacks to using dead synthetic stuff as a replacement for living tissue.
currently have a 3d printed crown in my mouth. they patched the original broken tooth as best they could. scanned my mouth and the tooth. and while they were root canaling my tooth was printing. after they were done, my crown was installed and I went about my day with some minor soreness for about a week.
I would imagine printed dentures to be similar.
RFK never heard of this, so it couldn't be a real thing
Can they make them smaller than the one in the thumbnail? Otherwise, count me out
Go to a mortuary. Don’t have to wait for them to be grown.
Well hurry up!
Can they grow them with funky colours?
Give it time and there will be the option of Gigantic Corp paying for your teeth if you grow their logo on them.
Imagine an entire forensics department in the future identifying corpses by the ads on the teeth.
🤮
My Labrador has excellent teeth.
Man's best friend becomes man's best mouth.
are you going to train your dog to chew things for you
Labrador is happy to chew, will not give back.
Only take!! No give.
