Researchers have made a groundbreaking discovery that keratin, a protein abundant in hair, can effectively rebuild tooth enamel by bonding with minerals present in saliva. This innovative method has the potential to replace harmful plastic resins commonly used in dental procedures, offering a safer and eco-friendly alternative. With promising trial results, this ‘hair-to-tooth’ breakthrough could be commercially available within two years, paving the way for a significant transformation in oral health care and waste management. Imagine a future where your toothpaste is derived from your own hair, a scientifically-supported solution for restoring enamel damage and enhancing dental health.
