New gel regrows tooth enamel and could transform dentistry

Researchers have created a bioinspired gel that can regenerate tooth enamel by mimicking natural growth processes. The fluoride-free material forms a mineral-rich layer that restores enamel’s strength and structure while preventing decay. It can even repair exposed dentine and reduce sensitivity. Early testing shows it performs like natural enamel, with potential for rapid clinical use.
