Toothpaste Made from Hair Could Help Repair and Protect Teeth
A Breakthrough Discovery in Dental Science Researchers from King’s College London have made a surprising discovery — toothpaste made from hair could one day help repair and protect damaged teeth. The study reveals that keratin, a natural protein found in hair, skin, and wool, can rebuild tooth enamel and prevent early signs of decay. This finding opens new doors in dentistry, offering a sustainable and biological way to strengthen teeth without relying on traditional synthetic materials. How Keratin Helps Repair Tooth Enamel Keratin plays a crucial role in maintaining the structure of hair and skin. According to the research, when keratin is applied to the surface of a tooth and interacts with the minerals found in saliva, it forms a highly organized, crystal-like structure. This structure closely mimics natural enamel, creating ...
