Sheep Hair to Prevent Tooth Decay 🐑🦷

Researchers in England have discovered that keratin from sheep wool can repair tooth enamel and prevent cavities. This protein forms a protective crystalline layer on teeth, mimicking natural enamel. Sustainable, low-cost, and closer to the tooth’s natural color, keratin could transform dental care for over 2 billion people affected by tooth decay.
