Researchers at King’s College London have made a groundbreaking discovery about a potential new use for keratin, a protein found in hair, skin, and wool. They have found that this protein could be used to repair and protect damaged teeth. The study suggests that keratin can create a protective coating similar to natural enamel when it interacts with minerals in saliva. This innovative approach could revolutionize dental treatments and provide a more sustainable and eco-friendly alternative.
The research, led by Sara Gamea, a PhD researcher at KCL, indicates that keratin extracted from sources like wool could be the key to a new kind of toothpaste. By mimicking the structure and function of natural enamel, the keratin-based material offers a solution to early stages of decay and enamel erosion. The study, recently published in Advanced Healthcare Materials, highlights the potential benefits of using this natural biomaterial sourced from waste products like hair and skin.
Traditionally, dental restorations have relied on toxic plastic resins, which are both harmful to the environment and less durable. However, with the development of keratin-based dental products, such as toothpaste, the need for plastic resins could be eliminated. This innovative approach not only tackles dental issues but also promotes sustainability and reduces the use of harmful chemicals in dentistry. The researchers are hopeful that this technology could be available within the next two years, offering a more natural and effective solution for oral health care.
Dr. Sherif Elsharkawy, a senior author and consultant in prosthodontics at KCL, shared his excitement about the potential of biotechnology to restore biological function with the body’s own materials. He emphasized the importance of finding industry partnerships to further develop this innovative approach. With continued research and collaboration, the researchers believe that something as simple as a haircut could contribute to growing stronger, healthier smiles in the future
