Story summary

Researchers at the University of Nottingham have developed a protein-based gel to repair and regenerate tooth enamel, addressing enamel degradation affecting nearly 50% of the global population.
The gel mimics enamel-building proteins and uses calcium and phosphate from saliva to fill holes and cracks.
Electron microscopy shows significant enamel-structure improvement after two weeks.
The gel is fluoride-free and can be applied quickly.
