Japanese scientists test new drug to regrow teeth A drug that can regenerate teeth is set to enter human testing at Kyoto University Hospital. Following promising results in animal studies, where new teeth successfully grew in mice and ferrets, this world-first trial aims to assess the drug's efficacy and safety in human subjects. The drug functions by deactivating a protein called USAG-1, which naturally suppresses tooth growth. By blocking USAG-1, the drug triggers bone growth and, consequentl

Researchers in Japan are developing a new medication designed to stimulate the body to grow natural teeth again, potentially replacing the need for implants or dentures. The drug works by blocking a protein called USAG 1, which normally prevents new tooth formation. When this protein is suppressed, tooth growth is allowed to restart. Earlier studies in animals such as mice and ferrets showed successful tooth regeneration, leading scientists to begin testing the approach in humans. The first huma
