Scientists create gel that regrows tooth enamel

Scientists at the University of Nottingham have developed a gel that can regenerate tooth enamel, potentially solving a problem that has long plagued dentistry. Unlike existing fluoride treatments that merely slow decay, this protein-based gel mimics the natural proteins that build enamel during childhood, according to research published in Nature Communications.

The gel works by creating a scaffold that draws calcium and phosphate from saliva to form new mineral structures through a process known as "epitaxial mineralization." When applied to damaged teeth, it fills cracks and holes while promoting organized crystal growth that integrates seamlessly with existing healthy tissue. Testing showed the regenerated enamel performs just like natural enamel when subjected to brushing, chewing, a
