University of Nottingham researchers say new gel could regrow tooth enamel in weeks

Researchers at the University of Nottingham have successfully developed a gel designed to help restore damaged tooth enamel within weeks- major research that proposes a novel strategy to repair enamel and advance preventive dental care.

The development of a protein-based gel helped in mimicking natural enamel formation by pulling calcium and phosphate from saliva to regrow organized crystals on damaged teeth, meanwhile, lab tests showed it withstands brushing, chewing and acidic foods performing like healthy enamel while providing relief from tooth sensitivity.

The study published in Nature Communications showed that the gel is heading toward commercialization by late 2026 or 2027 with Professor Alvaro Mata calling it safe and age-inclusive. According to reports, it fills holes and cracks, integrates with your existing tooth structure, and behaves just like natural enamel.

Nonetheless, this is not just for cavities as it can also treat exposed dentine helping with hypersensitivity and making dental restorations bond better, effectively ending the need for traditional fillings as we know them.
