The world’s first human trial of a drug that can regenerate teeth will begin in a few months, less than a year on from news of its success in animals. This paves the way for the medicine to be commercially available as early as 2030.
The trial, which will take place at Kyoto University Hospital from September to August 2025, will treat 30 males aged 30-64 who are missing at least one molar. The intravenous treatment will be tested for its efficacy on human dentition, after it successfully grew new teeth in ferret and mouse models with no significant side effects.
Following this 11-month first stage, the researchers will then trial the drug on patients aged 2-7 who are missing at least four teeth due to congenital tooth deficiency, which is estimated to affect 1% of people. The team is recruiting for this Phase IIa trial now.
Researchers are then looking at expanding the trial to those with partial edentulism, or people missing one to five permanent teeth due to environmental factors. The incidence of this varies from country to country, but it’s estimated around 5% of Americans are missing teeth, with a much higher incidence among older adults.
The medicine itself deactivates the uterine sensitization-associated gene-1 (USAG-1) protein, which suppresses tooth growth. As we reported in 2023, blocking USAG-1’s interaction with other proteins encourages bone morphogenetic protein (BMP) signaling, which triggers new bone to generate.
I had dental neglect as a kid, it’s hard to maintain and keep up that routine.. this will be amazing if available to us common folk and not the wealthy.
Finally… my teeth got destroyed from ten years of H. Pylori. Finally… I might have a chance to not look like a mess.

Cool now if I can just miraculously bust my ass and get into a high paying career I’ll be on my way! Seriously though that’s great news.
Just to clarify some things for the ‚common‘ folks: we have been trying to grow new organs (teeth included) for a good while. And while most studies are still in animal testing or earlier stages (many of which didn’t make it past that), some have actually made it to human testing. And yet, to this day we can’t create perfectly functioning organs, though I’ll have to add that a select few got pretty damn close to it, but those used different techniques that are extremely expensive and time consuming. And long term side effects are still largely untested to my knowledge because the animals are sacrificed for one and they are not humans while for the humans, like in this instance, the trials usually involved a very small sample so, not enough to make any conclusions.
I’ll be keeping an eye on the results of this trial but personally, I don’t think we are ready to see working new organ generation (neo organogenesis to be more accurate) by 2030, but who knows.
