Keratin breakthrough repairs damaged enamel

Researchers at King's College London are exploring the use of keratin, a protein derived from human hair, to repair damaged tooth enamel. Early laboratory tests indicate that this keratin-based formula can effectively restore defective enamel lesions, improving both their optical and mechanical qualities.

The innovative process involves applying keratin, which then forms a crystal-like structure upon contact with minerals in saliva. This structure attracts calcium and phosphate, creating a durable layer that mimics natural enamel and shields teeth from further acid wear, thereby relieving sensitivity.

This sustainable approach utilizes discarded keratin from sources like wool or hair, turning waste into a potential health product. While promising, further testing is required to assess its clinical applicability, durability, and scalability for widespread use in everyday toothpaste or dental treatments.
