I’ve been hearing about re-growing teeth for 20 years. Still nothing. It’s right up there with nuclear fusion.
Cold nuclear fusion. We were quite successful with the hot kind, uncontrolled.
I mean, we can make fusion happen, but it's not exactly useful outside of turning things into not things anymore.
Not just cold fusion. We are still working on creating hot fusion reactions that are controlled. That honestly makes sense. It's kinda weird that we were able to theorize the uncontrolled reaction of fission, and then used that to create a mostly kinda stable controlled fission reactor.
Popular mechanics is a terrible source. They post click bait trash like this on a consistent basis.
Been hearing this claim for 20 years. Let me know where and when I can sign up for the trails.
It's always 5 years away though, this one is 4! We're making progress.
Not only does it need to become possible, it needs to become more effective than other treatments like crowns and implants. I think it’s going to be a long time, and even then will only be applicable in limited cases for a long time, and will be really expensive.
No they won't.
This is the same as "humans may live on a mara colony in 10 years!"
No they won't, not even close.
This article is bullshit and so is the entire site, it's all djinn economy, all wishes and fantasy with a clickbait header to make sure you go there to watch the ads to make them money.
It's the same study that's been in process for about a decade. It entered human trials last year with those trials expected to take 5 years. Growing teeth is slow. It's not really being pushed, it's just the same reliable hit for various news sites to break out on slow news days.
If you only care about technology that's commercially available, why are you on the technology community?
Maybe they care about other technologies that aren't constantly just a couple years away?
i keep seein this story with zero details on application efficacy.. and now i see a thing where theyre giving the drug intravenously??
how do they know it will grow a tooth in a human being and how does it target a lost tooth if not administered directly?
I'm reminded of the phrase vagina dentata
I've seen one of these talked about before, and the mechanism seemed to be in that one that there's a gene in our DNA that triggers us to grow new teeth (that's how we replace our baby teeth with adult teeth), but that that gene turns off after we grow in our set of adult teeth. It's apparently the same gene that allows sharks to grow new teeth. What the drug does is it turns that gene back on, allowing us to grow new teeth to replace lost ones.
This might not be the same study though, as I've also seen one previously years ago that was about a drug that turned on a gene in our teeth to allow them to repair the enamel in them and fill in cavities by putting biodegradable gauze soaked in the drug inside a cavity and letting the tooth do the rest.
Nah. Because

Sweet dreams.
Nothing new in this article, it's just rehashing stuff that's already been announced and talked about since last year.
Not a dentist, but isnt the root cause of a lot of our dental problems, the loss of gums and the inability of our stupid gums to heal and grow back?
I’ve had gum grafts, and they’ve had no difficulty healing and growing back. I’ve also had extra teeth removed and the gums have had no difficulty filling in the gaps. So if all else fails, pull the old tooth, plant the new seed tooth, let the gum heal and then rupture as the new tooth grows out. Should have a nice healthy gum edge again. Although teething as an adult sounds… uncomfortable.
gum disease, and CARIES, some people are more susceptible to caries than others. anyone with dry mouth will have increased amount of plaque, cavaties. my old dentist said people on chemo have the worst dental health, because of they dry mouth from chemo. other people, such as prognathism,.
Gum disease could lead to tooth loss but the primary way people lose them is through infections due to cavities. The infection weakens the tooth and the jawbone it's rooted in as well as can lead to loss of the root nerve. At a certain point the tooth is too loose or weak and has to be removed to prevent further infection and/or to treat the existing infection.
I've been loosely following this company's progress for a bit. It doesn't say so in this article, but I think I recall reading that the drug also promotes gum regrowth at the same time.
Can they make it stop too? Not taking any chances on this.
[...] will administer the treatment to patients between the ages of 2 to 7 who are missing at least four teeth
Yeah, even if this is approved in some form.. growing new teeth for young children is not the same as for adults. Very weird this is the population they're testing on. I'd think they would be testing on people with 10+ missing teeth in their 40s, 50s, 60s+
[...]these treatments are currently focused on patients with congenital tooth deficiency
Again, not for us.
You skipped right past the paragraph before that one describing the adult study that needs to succeed prior to the start of the child study.
Now, scientists will see just how similar, because humans are undergoing a similar trial. Lasting 11 months, this study focuses on 30 males between the ages of 30 and 64—each missing at least one tooth. The drug will be administered intravenously to prove its effectiveness and safety, and luckily, no side effects have been reported in previous animal studies.
inb4 teeth growing in the most wrong and least expected places
This is my main concern. I will believe they can regrow lost teeth, but can they regrow them in the correct shape and location? Teeth can take some weird shapes. We've got millions of years of evolution tweaking exactly where and how they grow, and it still goes wrong sometimes. I suspect messing with that process can lead to Cronenbergian results.
A new, horrible torture method just dropped.
For some reason just thought of teeth in the pussy. Anyway just sharing here cause sharing is caring.
Better than growing a tongue in your asshole.
Bruh I'm gonna grow so many teeth. I wonder if we'll be able to get crocodile teeth.
Like can I get just one crocodile tooth that hangs over my lip?
Correction: rich humans
Everything is expensive at first, before getting cheaper in the long rub
yeah except all the things getting more expensive year after year
Like cars? Televisions? Home appliances?
By the way:
Basic Model T price in 1909: $825 or $30,000 today.
Basic sedan price in 2025: $30,000
Average price of a car in 2025: $50,000
Cost of model T in 1913: $14,000
Cost of model T in 1916: $9,000
See how the price went down after its 1909 release ? 😁
Popular Mechanics wrote an article saying exactly this same thing like 10 years ago.
That's it. Not gonna brush my teeth anymore. Just gonna grow new ones. Maybe sell them. Grow more. Smile big.
Okay but... what kinna teeth we talkin..? Any teeth?
I'd kill for some sharper canines lol
Mine are so sharp the dentist asked if I wanted them dulled a bit. I of course told him to leave em sharp!
like this?
That's a long time to grow a tooth. Can they do anything to speed that up? I'd like a new set of chompers by next week.
