Dental treatments from sheep’s wool and other hair could be used to coat teeth to repair enamel and prevent tooth decay, according to a new study. After extracting keratin — a protein found in hair, skin and fingernails — from wool and applying it to teeth, scientists found that the substance formed a protective crystal-like coating that mimicked natural tooth …
