Scientists in London have discovered that keratin, a protein found in human hair, could revolutionize dental care by repairing tooth enamel and preventing cavities. Laboratory tests show keratin-based treatments can halt enamel erosion and reverse early decay by forming a crystal-like structure that attracts minerals to create a protective layer. While promising, the method is still in its early stages and requires further development for widespread use.
Researchers at King’s College London experimented with keratin, the same natural protein found in hair, skin, and nails, on teeth. In lab tests, the system
