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.
