These bones act as a natural support system, enabling us to move, work, and live our daily lives. What’s remarkable is that bones can heal and grow back if broken. Teeth, however, are different. Although they are the hardest substance in the human body—thanks to their protective enamel—they cannot naturally regrow once damaged or lost. But this may soon change, as Japanese scientists are working on a revolutionary drug that could allow teeth to regrow naturally in humans. The Beginning of Human Trials In September 2024, researchers at Kitano Hospital Medical Research Institute in Osaka, led by Dr. Katsu Takahashi , began clinical trials on a new drug aimed at regenerating teeth. The project follows years of study on a specific protein called Uterine Sensitization-Associated Gene-1 (USAG-1) , which is known to suppress tooth growth. In earlier experimen...
