The only toothpaste based MicroRepair ®, which restores the tooth enamel and bleaches naturally. Interaction between remineralizatsionnoto action MicroRepair ® and bleaching effect of PVP polymer ensures natural and healthy white. When you brush your teeth with Biorepair®, microRepair® microparticles of hydroxyapatite are released. Hydroxyapatite is virtually identical to enamel and that"s what makes Biorepair® such an effective enamel repairing toothpaste. These microRepair® microparticles are so small, they can get into the tiny cracks and crevices on the surface of your teeth often caused by acid erosion. They then fill in the cracks and bind to the enamel - actively repairing tooth enamel.Repairing tooth enamel The microRepair® microparticles act on tooth enamel by filling in microscopic fissures, scratches and surface enamel lesions, smoothing out any roughness and repairing the surface, making the tooth look more radiant. Preventing decay By filling in the tiny holes to repair the damaged enamel surface, the microRepair® microparticles help to prevent plaque and bacteria from forming and leading to more serious damage such as tooth decay. Reducing sensitivity The microRepair® microparticles strongly bind to the tooth enamel and fill in the tiny holes, forming a protective layer over any exposed nerve endings. This gives effective long-term relief from dental sensitivity.
