King’s Faculty London researchers have found that keratin—a protein present in hair, pores and skin and wool—can restore tooth enamel and arrest early decay by forming a protecting, enamel-like coating.
Their examine, printed in Superior Healthcare Supplies, discovered that when keratin extracted from wool is utilized to the tooth and comes into contact with minerals in saliva, it builds a extremely organised, crystal-like scaffold that mimics pure enamel construction and performance. Over time, the scaffold attracts calcium and phosphate ions, selling the expansion of a protecting enamel-like layer.
Not like bones and hair, tooth enamel can not regenerate, so this represents a major breakthrough in regenerative dentistry. Researchers consider keratin therapy could possibly be delivered as a each day toothpaste or as an expert gel utility, probably obtainable to the general public in about two to a few years.
‘So simple as a haircut’
“We’re getting into an thrilling period the place biotechnology permits us to not deal with signs alone however to revive organic perform utilizing the physique’s personal supplies. With additional improvement and the correct business partnerships, we might quickly be rising stronger, more healthy smiles from one thing so simple as a haircut,” says Dr Sherif Elsharkawy, senior creator and prosthodontics advisor at King’s Faculty London.
In the meantime, PhD researcher Sara Gamea, first creator of the examine, provides: “Keratin presents a transformative different to present dental remedies. It’s sustainably sourced from organic waste like hair and pores and skin and removes the necessity for plastic resins generally utilized in restorative dentistry, that are poisonous and fewer sturdy. It additionally extra carefully matches the pure tooth color.”
As considerations enhance over healthcare sustainability and long-term fluoride use, keratin emerges as a promising, biodegradable different that faucets round financial system rules and turns waste right into a health-promoting useful resource.
