A new protein-based gel can regenerate tooth enamel.

For generations, dental patients have accepted a hard truth: once tooth enamel is lost, it is gone for good. A major scientific breakthrough has now challenged that limitation.

An international research team led by scientists at the University of Nottingham has developed a biomimetic gel capable of repairing and regenerating damaged tooth enamel. The findings were published in Nature Communications. This fluoride-free treatment uses lab-engineered proteins that mimic the natural processes of enamel formation during infancy.

When applied to the teeth, the gel creates a microscopic scaffold that captures calcium and phosphate ions from the patient’s saliva. It then systematically grows a new mineral layer that integrates seamlessly with the tooth’s original structure.

The innovative gel offers a painless, drill-free alternative to traditional fillings and crowns, which only mask damage rather than heal it. Clinical trials for the biocompatible gel are planned to begin this year, and the development team is already collaborating with the spin-off company Mintech-Bio with the aim of releasing a first commercial product as early as next year.

By providing a permanent, easy-to-apply solution for acid erosion and early-stage cavities, this regenerative technology could fundamentally change routine dental care and spare millions of patients the discomfort of the dental drill.

Quel bel exemple de mauvaise gestion à l’Autorité régionale de transport métropolitain. L’ARTM accorde un contrat de 1,13 million $ + redevance sur 7 millions de transactions annuelles pour la fabrication d’une app pour charger la carte Opus sur le téléphone alors qu’un étudiant de McGill en a fait une lasse d’attendre celle de l’ARTM depuis des années ! https://t.co/JK9mnN0MV3
