Everyday fluoride-free remineralisation with enamel-like mineral.
Tooth enamel is approximately 96–97% mineral by weight, and that mineral is mainly hydroxyapatite. Biorepair Plus Total Protection contains 200 mg/g (20%) microRepair® zinc-hydroxyapatite for everyday oral care.
During brushing, these biocompatible calcium-phosphate particles deposit onto the enamel surface, bind to microscopic irregularities and support the remineralisation of early surface mineral loss. With regular twice-daily use, they help form a temporary biomimetic mineral coating over enamel-surface micro-scratches.
20% microRepair® zinc-hydroxyapatite
Deposits enamel-like calcium and phosphate onto the tooth surface
Supports everyday enamel remineralisation
Biocompatible, fluoride-free formula for twice-daily brushing
Why choose hydroxyapatite? Fluoride and hydroxyapatite both support remineralisation in different ways. Hydroxyapatite takes a biomimetic approach, supplying enamel-like mineral directly to the tooth surface. Clinical studies have found hydroxyapatite toothpastes comparable with fluoride toothpastes for remineralising early enamel lesions under the conditions tested.
Choose Total Protection for versatile daily fluoride-free care with 20% microRepair®.
