A gel that regrows tooth enamel? UK team aims for first product in 2027

The University of Nottingham has developed a fluoride-free, protein-based gel that fills microscopic cracks in enamel and draws calcium and phosphate from saliva to grow a new mineral layer aligned with the existing tooth. In lab tests simulating brushing, chewing and acidic food, the restored enamel performed like healthy enamel. A spin-out company is commercialising it, aiming for a first product in 2027.

What it means for you

Lost enamel has never been able to grow back; this could help sensitivity and erosion in future, but so far the results are from the lab only.

Key points

• Lab results only; no human trial data yet
• First product targeted for 2027
• For now: fewer acidic drinks and fluoride toothpaste
