Humans may never need dentures again. 🦷 Researchers at Kyoto University Hospital in Japan have begun human trials for a drug designed to stimulate the growth of entirely new teeth. The drug targets a protein called USAG-1, which normally suppresses tooth development. By blocking this protein, the treatment reactivates dormant tooth buds, potentially triggering a third set of teeth. The first phase involves 30 healthy adult males aged 30 to 64, each missing at least one molar, with the study focused on safety and proper dosing. Dr. Katsu Takahashi, head of dentistry at the Medical Research Institute Kitano Hospital, confirmed that humans already carry a third set of tooth buds embedded in their mouths, waiting to be activated.
Human trials are being led by Toregem Biopharma, a biotech startup co-founded by Dr. Takahashi through Kyoto University, marking the world's first peptide-based attempt to regrow teeth in humans. 🔬 Preclinical results were already demonstrated successfully in mice and ferrets before moving to human subjects. Future trial phases will include children aged 2 to 7 born with congenital anodontia, a condition affecting roughly 1 percent of the global population. Imagine a child who never smiled freely finally growing their own teeth. 😮 If trials continue showing positive results, Toregem Biopharma anticipates commercial availability by 2030.
