Dental therapies from sheep’s wool and different hair could possibly be used to coat tooth to restore enamel and forestall tooth decay, in accordance with a brand new examine.
After extracting keratin — a protein present in hair, pores and skin and fingernails — from wool and making use of it to tooth, scientists discovered that the substance shaped a protecting crystal-like coating that mimicked pure tooth enamel.
The discovering may assist sustainable, low-cost therapies for early tooth decay throughout the subsequent two to 3 years, in accordance with the researchers.They reported their findings August 12 within the journal Superior Healthcare Supplies.
“Keratin affords a transformative different to present dental therapies,” examine coauthor Sara Gamea, a dentistry researcher at King’s Faculty London, stated within the assertion. “Not solely is it sustainably sourced from organic waste supplies like hair and pores and skin, it additionally eliminates the necessity for conventional plastic resins, generally utilized in restorative dentistry, that are poisonous and fewer sturdy. Keratin additionally appears far more pure than these therapies, as it will probably extra intently match the colour of the unique tooth.”
Untreated tooth decay is the world’s most typical oral well being situation, affecting some 2 billion individuals worldwide. Over time, acidic meals, poor oral hygiene, and on a regular basis put on and tear can break down the protecting enamel that covers an individual’s tooth. Shedding that enamel can result in ache, cavities and tooth loss.
“Not like bones and hair, enamel doesn’t regenerate,” examine coauthor Sherif Elsharkawy, a researcher specializing in prosthodontics at King’s Faculty London, stated in a assertion. “As soon as it is gone, it is misplaced ceaselessly.”

To research whether or not keratin-based therapies may assist cease tooth decay and restore enamel, Elsharkawy and his colleagues first extracted keratin from wool fibers. Then they combined the keratin with water, the place it shaped a skinny movie.
After making use of the keratin movie to a tooth pattern, the scientists discovered that it shaped an ordered, sturdy and crystal-like coating much like organic enamel when it got here in touch with minerals in saliva. Over the course of a month, the coating attracted calcium and phosphate ions, build up a tough, protecting layer over the tooth.
The scientists are exploring methods to carry the keratin remedy to the general public. Keratin toothpastes for day by day use or skilled coatings utilized at a dentist’s workplace could possibly be out there throughout the subsequent few years, in accordance with the assertion.
“We’re getting into an thrilling period the place biotechnology permits us to not simply deal with signs however restore organic operate utilizing the physique’s personal supplies,” Elsharkawy stated. “With additional growth and the correct business partnerships, we could quickly be rising stronger, more healthy smiles from one thing so simple as a haircut.”
