Toothpaste Made with Hair Protein Repairs Teeth

Scientists at King's College London have made an exciting discovery about tooth care. They found that keratin, a protein found in hair, can be used to repair damaged teeth. This could be a big change in how we protect our teeth.

Currently, we use fluoride in toothpaste and drinking water to slow down tooth damage. However, the new keratin treatment might be even better. It can actually stop tooth enamel from breaking down completely.

The researchers say this new toothpaste will look and feel like regular toothpaste. It will be minty and foamy, but it will contain keratin instead of fluoride. They hope to make it available to everyone within a few years, and they want it to be affordable.

This discovery could change how we take care of our teeth in the future. It offers a new way to protect and heal tooth enamel, which doesn't naturally repair itself.
