Revolutionary enamel repair: Hair-derived Keratin is the future of dentistry
A groundbreaking new study spearheaded by King’s College London has revealed an eco-friendly and effective method for enamel repair and protection, using keratin—a protein commonly found in hair, skin, and wool. This innovation could change the way we treat sensitive, eroded, or weakened teeth.
How it works:
When keratin is applied to the tooth surface—either through a toothpaste or professional gel application—and interacts with naturally occurring minerals in saliva, it forms a crystalline scaffold that mimics the structure and function of natural enamel. Over time, this scaffold attracts calcium and phosphate, strengthening the protective layer of the tooth and sealing exposed nerve channels, significantly reducing sensitivity.
The main benefits to the teeth will be:
- Reduced sensitivity
- Enhanced protection of the enamel.
- Sustainable option, being sourced form hair and and wool,
- A great and greener alternative to the conventional plastic resin materials we currently use.
At Covent Garden Dental Spa, we’re excited about new research showing how hair-derived keratin could be used in toothpaste or enamel gels to help repair and regenerate tooth enamel. This breakthrough could make routine enamel regeneration as simple as brushing your teeth or visiting the dentist — offering our patients stronger teeth, lasting sensitivity relief, and a sustainable, natural approach to dental care.
