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’t regenerate, so this represents a major breakthrough in regenerative dentistry. Researchers consider keratin therapy may very well be delivered as a day by day toothpaste or as knowledgeable gel software, probably out there to the general public in about two to 3 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 operate 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 writer and prosthodontics marketing consultant at King’s Faculty London.
In the meantime, PhD researcher Sara Gamea, first writer of the examine, provides: “Keratin gives a transformative different to present dental therapies. 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 intently matches the pure tooth color.”
As considerations improve over healthcare sustainability and long-term fluoride usekeratin emerges as a promising, biodegradable different that faucets round financial system ideas and turns waste right into a health-promoting useful resource.
