A Step Towards Painless Treatment: Enamel Restoration from Hair? Challenging "Cavity Repair" with Wool Keratin

Applying keratin, found in materials like wool, to the tooth surface can react with the calcium and phosphate in saliva to form an enamel-like crystal layer, potentially halting the progression of early tooth decay. This research was conducted by a team from King's College London and published in Advanced Healthcare Materials. While future applications are envisioned for toothpaste, mouthwash, and dental gels, the current stage is at the laboratory level, with clinical trials, long-term durability, and regulatory approval remaining as future challenges. On social media, there is both surprise and anticipation with comments like "Toothpaste from hair?" while cautious opinions also stand out, such as "I want to avoid animal-derived products" and "Is it really stronger than fluoride?" In conclusion, while keratin could become a new asset in regenerative treatments, it is wise to continue with existing preventive measures (fluoride, diet, regular check-ups) while awaiting further updates.
