Researchers develop fluoride-free gel for tooth enamel regeneration

Researchers have developed a new fluoride-free gel capable of regenerating damaged tooth enamel. By mimicking the biological processes that occur during childhood enamel formation, the gel fills microscopic cracks on the tooth surface. It works by attracting calcium and phosphate ions from saliva to rebuild a mineral layer that is structurally similar to healthy enamel.

Unlike traditional fluoride treatments that primarily harden the surface, this biomimetic approach creates a new mineral structure. Research data indicates the gel achieves a 92% mineral deposition rate and an 88% depth of natural enamel restoration, representing a significant advancement in preventive dentistry.
