Our fluoride-free varnish with hydroxyapatite is a natural, effective solution for strengthening teeth and reversing early cavities. Ideal for those with chronic tooth sensitivity, demineralized enamel, or active cavities, it helps remineralize and protect the teeth. This varnish is also great for individuals with hypoplastic enamel, those undergoing orthodontic treatment, or anyone at high risk for cavities. Hydroxyapatite works in a biomimetic way to whiten teeth while providing extra protection for sensitive or weakened enamel—without fluoride.
