Japanese researchers studying potential tooth regrowth breakthrough

Japanese researchers are studying tooth regrowth, a potential breakthrough in dental care. They are focusing on an antibody related to the uterine sensitization gene, which has shown promise in stimulating tooth growth in mice. Human trials for this treatment began in September 2025. The head of dentistry at Kitano Hospital, Katsu Takahashi, expressed hope for helping those with tooth loss, noting previous successful studies on ferrets. The ongoing study is expected to last 11 months. Researchers aim to provide a permanent solution for tooth loss, addressing a long-standing gap in dental treatments.
