According to a shocking discovery from King’s College London, toothpaste containing human hair proteins may aid in tooth restoration and possibly stop excessive tooth loss.
Keratin, a naturally occurring protein in wool, skin, and hair, has also been shown by researchers to be important for tooth protection. Keratin, which is already found in shampoos and cosmetics, could soon be incorporated into toothpaste as a vital component for oral health.

King’s College London’s Dr. Sherif Al-Sharkawi referred to the finding as a “game changer,” pointing out that keratin-based solutions have the potential to completely transform dental care. “Your tooth will heal itself without you even noticing it if you have a microcrack or a very small defect,” he said.
Where enamel repair is most important
Once injured, the tooth’s enamel, or outside layer, cannot be repaired by nature. Weakened enamel is the root cause of many common dental problems, including cavities and sensitivity.
According to the study, keratin can potentially fix minor flaws before they become more serious by forming a protective layer that resembles the structure of natural enamel when it combines with minerals in saliva.
A new generation of toothpaste that actively repairs teeth in addition to protecting them may be made possible by this creative technique. Although more research is required before keratin toothpaste is commercially available, researchers think this could be a game-changer for preventive dentistry.
