Researchers have created a biomimetic dental gel capable of regenerating tooth enamel, something long believed to be impossible in humans. Tooth enamel is the hardest substance in the human body, yet once damaged by decay or erosion, it does not naturally grow back. This new gel changes that assumption by triggering enamel-like regrowth at the molecular level. Instead of drilling or filling cavities, the gel works by replicating the natural mineralization process that forms enamel during tooth d

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
