Scientists have discovered that keratin, a protein found in hair, skin, and wool, can repair tooth enamel and prevent tooth decay, potentially surpassing fluoride toothpaste. Keratin forms a protective coating mimicking natural enamel, repairing damage and sealing exposed nerves. Extracted from wool or human hair, it offers a sustainable, biodegradable alternative to traditional toothpastes, potentially hitting the market within two to three years. This breakthrough in regenerative dentistry promises healthier smiles and reduces reliance on toxic materials.
