Toothpaste Made with Hair Protein Repairs Teeth

In a groundbreaking study, scientists at King's College London have unveiled a potential paradigm shift in dental care: toothpaste infused with keratin, a protein abundant in hair, that could naturally repair tooth enamel and halt early-stage decay.

Dr. Sherif Elsharkawy, from the Faculty of Dentistry, Oral & Craniofacial Sciences, heralds this discovery as a 'game changer.' The keratin-based treatment surpasses the current standard of fluoride, which merely slows enamel erosion. When keratin interacts with salivary minerals, it forms a protective coating that mimics the structure and function of natural enamel, effectively stopping erosion in its tracks.

This innovation addresses a fundamental limitation in dental health: the inability of tooth enamel to regenerate naturally. The keratin treatment offers a non-invasive solution to repair micro-cracks and small defects, potentially revolutionizing preventative dental care.

The researchers envision this technology being incorporated into daily toothpaste or applied as a professional gel treatment. Remarkably, the keratin used in these products is derived from sustainable sources like sheep's wool, aligning with eco-friendly practices. The team aims to make this transformative product widely accessible and affordable within the next two to three years, promising a new era in dental health maintenance.
