Researchers at the University of Nottingham have developed a protein-based gel that can regenerate tooth enamel, published in Nature Communications on 4 November 2025. The gel works by mimicking the proteins that guide enamel formation during tooth development, a process the body cannot repeat once enamel is lost to erosion or demineralisation.

When applied to a tooth surface, the gel forms a thin layer that draws calcium and phosphate ions from saliva and organises them into new enamel through epitaxial mineralisation. The result integrates with existing tooth structure and, under simulated brushing, chewing, and acid exposure, performs mechanically like natural enamel. The material contains no fluoride and can also be applied to exposed dentine, reducing sensitivity and improving how restorations bond to the tooth.

For dental professionals, the practical implications depend on how quickly the technology reaches the clinic. The University of Nottingham spin-out Mintech-Bio is developing commercial products and has indicated a first product could be available in 2026. If that timeline holds, clinicians may soon have a remineralisation option that goes beyond symptom relief to rebuild enamel structure directly.
