A protein found in hair leads to stronger, healthier teeth.

London – (Special Correspondent / Web Desk) – Scientists have made an exciting discovery: a new toothpaste that uses a protein from your own hair. This special ingredient, called keratin, can help fix and strengthen weakened tooth enamel.

Keratin is a natural protein found in our hair, skin, and even wool. When used in toothpaste, it forms a protective shield over the tooth. Minerals in your saliva then work with this layer to act just like strong, natural enamel, helping to stop early cavities.

A lead researcher, Sarah Gamia, explains that keratin is also great for our planet. It can replace the plastic materials used in some toothpastes, which can be bad for the environment and not as strong.

Here’s how it works:The keratin paste creates a crystal-like surface on your tooth. This surface attracts important minerals like calcium and phosphate. Together, they build a new, strong layer that protects your teeth from decay.

As expert Dr. Sharif Al-Sharkawi notes, our bodies cannot grow back lost tooth enamel. But thanks to this new biotechnology, we can now do more than just treat pain. We can actually help restore the tooth’s original protective surface.
