Japanese Scientists Begin Human Trials for Tooth Regrowth Drug 

Imagine a world where, instead of getting a dental implant, your body regrows a missing tooth. This isn’t science fiction anymore. It may become a reality. 

In October 2024, researchers at Kyoto University Hospital in Japan commenced human trials for a novel drug designed to stimulate the growth of new teeth. This innovative approach targets a protein called USAG-1, which typically suppresses tooth development. By inhibiting this protein, the drug reactivates dormant tooth buds, potentially leading to the growth of a third set of teeth in humans . 

The initial phase of the trial involves 30 healthy adult males aged 30 to 64, each of whom is missing at least one tooth. The primary goal is to assess the safety of the drug and determine the appropriate dosing. If successful, subsequent phases will focus on children aged 2 to 7 who suffer from congenital anodontia—a condition where individuals are born without a complete set of teeth. 

Dr. Katsu Takahashi, who leads the research at the Medical Research Institute of Kitano Hospital in Osaka, has been at the forefront of this study. His team’s earlier experiments demonstrated that blocking USAG-1 in mice and ferrets led to the successful growth of new teeth. These promising results paved the way for the current human trials . 

While this development is exciting, it’s essential to note that the drug’s widespread availability is still years away. Researchers aim for a potential release around 2030, pending the outcomes of ongoing and future trials .
