Oral treatments from sheep’s wool and other hair might be utilized to coat teeth to fix enamel and avoid dental caries, according to a brand-new research study.
After drawing out keratin– a protein discovered in hair, skin and fingernails– from wool and using it to teeth, researchers discovered that the compound formed a protective crystal-like covering that imitated natural tooth enamel.
The finding might support sustainable, inexpensive treatments for early dental caries within the next 2 to 3 years, according to the researchers.They reported their findings August 12 in the journal Advanced Healthcare Materials“Keratin offers a transformative alternative to current dental treatments,” research study coauthor Sara Gameaa dentistry scientist at King’s College London, stated in the declaration. “Not only is it sustainably sourced from biological waste materials like hair and skin, it also eliminates the need for traditional plastic resins, commonly used in restorative dentistry, which are toxic and less durable. Keratin also looks much more natural than these treatments, as it can more closely match the color of the original tooth.”
Unattended dental caries is the world’s most typical oral health conditionimpacting some 2 billion individuals worldwide. In time, acidic foods, bad oral health, and daily wear and tear can break down the protective enamel that covers an individual’s teeth. Losing that enamel can cause discomfort, cavities and missing teeth.
“Unlike bones and hair, enamel does not regenerate,” research study coauthor Sherif Elsharkawya scientist focusing on prosthodontics at King’s College London, stated in a declaration “Once it’s gone, it’s lost forever.”

To examine whether keratin-based treatments might assist stop dental caries and repair work enamel, Elsharkawy and his associates initially drawn out keratin from wool fibers. They blended the keratin with water, where it formed a thin movie.
After using the keratin movie to a tooth sample, the researchers discovered that it formed a purchased, strong and crystal-like finishing comparable to biological enamel when it was available in contact with minerals in saliva. Throughout a month, the finish drew in calcium and phosphate ions, developing a hard, protective layer over the tooth.
The researchers are checking out methods to bring the keratin treatment to the general public. Keratin tooth pastes for day-to-day usage or expert finishes used at a dental practitioner’s workplace might be readily available within the next couple of years, according to the declaration.
“We are entering an exciting era where biotechnology allows us to not just treat symptoms but restore biological function using the body’s own materials,” Elsharkawy stated. “With further development and the right industry partnerships, we may soon be growing stronger, healthier smiles from something as simple as a haircut.”
