The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the child’s pillow, but they be assured of a replacement tooth in a few months. Unfortunately, the scenario is quite different for adults grappling with a loss of teeth. Luckily, there may be some hope thanks to a new study performed by scientists at Kyoto University and the University of Fukui.
A dental breakthrough
While the typical adult mouth houses 32 teeth, approximately 1% of the population exhibits variations of them, either possessing more or fewer teeth due to congenital conditions. Researchers have delved into the genetic factors behind cases of excessive teeth, seeking valuable insights into the potential regeneration of teeth in adults. This study is the first to show that monoclonal antibodies can help regrow teeth. It suggests a new way to treat a dental problem that currently requires implants and other artificial solutions.
A bit of science
The research team disclosed that an antibody targeting a specific gene, known as uterine sensitization-associated gene-1 (USAG-1), can induce tooth development in mice affected by tooth agenesis, a congenital condition. The findings were published in the journal, Science Advances.
As per Katsu Takahashi, a senior lecturer at the Kyoto University Graduate School of Medicine and one of the principal contributors to the study, the essential molecules crucial for the development of teeth have already been pinpointed. “The morphogenesis of individual teeth depends on the interactions of several molecules including BMP, or bone morphogenetic protein, and Wnt signaling,” says Takahashi.
On April 13, 2021, the University of Kyoto posted its first pic of newly-grown teeth in mice.
BMP and Wnt are involved in more than just tooth development; they affect the growth of organs and tissues early in the body’s development. Because drugs affecting them directly might have broad side effects, scientists are cautious. To find a potentially safer method, researchers focused on the gene USAG-1, thinking that aiming at factors countering BMP and Wnt specifically in tooth development could be more precise.
“We knew that suppressing USAG-1 benefits tooth growth. What we did not know was whether it would be enough,” added Takahashi.
The first results
Scientists looked at how different monoclonal antibodies affect USAG-1. Monoclonal antibodies are often used to treat things like cancer and arthritis and for making vaccines. Tests with this antibody showed that BMP signaling is crucial for deciding the number of teeth in mice. Also, just one treatment was enough to grow a whole tooth. Further tests confirmed these positive results in ferrets too.
“Ferrets are diphyodont animals with similar dental patterns to humans. Our next plan is to test the antibodies on other animals, such as pigs and dogs,” explained Takahashi.

The next steps
Now, scientists are going to test the drug on healthy adults. If that goes well, the team plans to try it on kids aged 2 to 6 with a rare tooth problem called anodontia, a genetic disorder defined as the absence of all teeth. These kids will get one shot of the drug to see if it makes their teeth grow. If everything works out, the medicine might be approved by 2030.
Takahashi sees the new medicine as an additional choice for individuals who are missing some or all of their teeth.
“The idea of growing new teeth is every dentist’s dream,” Takahashi told the Japanese newspaper, The Mainichi in June this year. “I’ve been working on this since I was a graduate student. I was confident I’d be able to make it happen.”
So hopefully, by the year 2030, humans will get a chance to have their third generation of teeth grown and say goodbye to implants. Until then, make sure to keep your teeth strong and healthy — this article will help you with that.

MICHAEL JACKSON’S SURROGATE SON BLANKET, 21, LOOKS ‘HANDSOME’ & ‘EXACTLY’ LIKE DAD, FANS CLAIM
Michael Jackson passed away in June 2009 due to cardiac arrest caused by an accidental drug overdose, leaving behind three children: Paris, Blanket (also known as “Bigi”), and Prince Jackson. On August 29, 2023, which would have been their late father’s 65th birthday,
Blanket and Prince were seen in Las Vegas after attending the “Michael Jackson ONE” show by Cirque du Soleil at Mandalay Bay Resort and Casino. Paris, the third sibling, was on tour with the rock band Incubus.
Prince, in blue jeans and a gray T-shirt, engaged with fans, receiving a drawing of Michael and returning the gesture with a hug. Blanket, rarely seen in public, wore black attire, and fans noted his resemblance to Michael.
During a TV interview in 2021, Blanket, also known as Prince Michael Jackson II, expressed his passion for environmentalism and urged people to address climate change.
Born on February 21, 2002, via surrogate, Blanket is the only biological child of Michael Jackson. Reports suggest that a Mexican nurse named Helena served as the surrogate, chosen by Michael, with a separate egg donor. At Prince’s Thriller Night Halloween Party in 2021,
Blanket highlighted the historical significance of their home and studio, reflecting his father’s essence. He emphasized the family’s desire to create things for people’s enjoyment and benefit.
Having no plans to pursue a musical career like his father, Blanket maintains a low profile and resides in Calabasas, California, in a house purchased in March 2020.
