Story summary

Researchers at the University of Nottingham developed a protein-based gel that repairs enamel.
Unlike fluoride treatments, the gel mimics natural enamel formation and can be applied quickly.
The gel seeps into microcracks and directs minerals from saliva to form organized crystals, restoring strength.
The gel also reduces tooth sensitivity and improves bonding for dental restorations.
Nature Communications published the findings, with researchers hoping for commercialization by next year.
