New Dental Gel Promises Enamel Regeneration

Background & Context
Enamel, the hardest tissue in the human body, protects teeth from pressure, temperature changes, acids and wear, yet it contains no living cells and cannot self-repair once lost. Current fluoride varnishes and remineralisation treatments can strengthen remaining enamel but cannot replace the original structure. Approximately half of the global population experiences enamel loss, a major contributor to tooth decay, pain, infection and broader health issues such as diabetes and cardiovascular disease.
Core Development and Testing
Researchers at the University of Nottingham’s School of Pharmacy and Department of Chemical and Environmental Engineering created a protein-based gel that mimics the natural proteins involved in enamel formation during infancy. The gel forms a thin, durable coating that penetrates cracks and pores, drawing calcium and phosphate from saliva to guide epitaxial mineralisation—new crystals grow aligned with existing enamel, restoring its microscopic architecture.
Post-doctoral fellow Dr Abshar Hasan explained that when the material is applied to demineralised enamel or exposed dentine, it promotes organized crystal growth that recovers the natural enamel structure. Mechanical tests that simulated brushing, chewing and exposure to acidic foods showed the regenerated tissue behaved similarly to healthy enamel, indicating durability for everyday use.
Potential Clinical Impact
The gel could address two common problems: (1) rebuilding enamel lost to mineral loss or erosion, and covering exposed dentine, which often causes sensitivity to temperature, sweetness or touch. By creating an enamel-like mineral layer over dentine, the treatment may reduce sensitivity while providing a stronger surface for dental restorations to bond.
Commercial Outlook
Professor Alvaro Mata, chair in Biomedical Engineering & Biomaterials and lead of the study, noted that the technology is designed for rapid, scalable application and is safe for patients of all ages. The researchers have launched a start-up, Mintech-Bio, and aim to release a first product within the next year, with the potential to be incorporated into various dental products worldwide.
