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
