What's Happening?
Researchers at King's College London have developed a new toothpaste using keratin, a protein found in hair, skin, and wool, which may offer better protection against tooth decay than traditional fluoride-based toothpastes. The study, published in Advanced Healthcare Materials, reveals that keratin forms a protective coating on teeth when it interacts with saliva, mimicking natural enamel and potentially repairing it. This innovative approach not only shields teeth from further damage but also provides a sustainable alternative to conventional dental treatments, which often rely on toxic plastic resins.

Why It's Important?
The introduction of keratin-based toothpaste could revolutionize dental care by offering a biodegradable and effective solution for enamel repair, addressing a significant gap in current dental treatments. This advancement is particularly crucial as tooth enamel erosion is irreversible and leads to increased sensitivity and dental issues. By utilizing biological waste materials, such as hair and skin, this new toothpaste also presents an environmentally friendly option, reducing reliance on non-biodegradable components in dental products.
What's Next?
The researchers anticipate that keratin-based toothpaste could be available to consumers within the next two to three years, pending further development and industry partnerships. This timeline suggests a potential shift in the dental care market, with companies likely to explore similar sustainable and regenerative solutions. The study's authors emphasize the importance of biotechnology in restoring biological functions, hinting at future innovations in dental and healthcare products.
