The microRepair® system consists of Hydroxyapatite crystals (Substituted-Carbonate-Apatite-Zinc): a mineral that makes up 90% of tooth enamel and 70% of dentine.
The microRepair® crystals have a special biomimetic capacity (i.e. an ability to totally imitate a component and its biological structure). This allows them to enter and repair tiny cracks on the teeth, adhering to the enamel for over 24 hours, preventing bacteria from penetrating, and so protecting the oral cavity from plaque, tartar and caries. In addition, thanks to their special structure, microRepair® crystals are able to form a chemical bond with the dentine, closing the dentinal tubules. This stops heat stimuli (both hot and cold) from reaching the nerve, and so prevents the discomfort of sensitive teeth. So the combination of the microRepair® particles, with their reconstructive and protective function, and the cleansing action of Zinc, enables us to avoid the use of fluoride in all BioRepair products.
