Biorepair® Fast Sensitive Repair immediately reduces dentinal sensitivity, and repairs enamel and thus closes exposed dentinal tubules. EFFECTS: - prevents tooth decay - prevents plaque - removes and prevents tartar build-up - closes the tubules, preventing thermal stimuli from reaching the tooth - prevents enamel erosion - prevents the loss of natural tooth whiteness What makes Biorepair® Fast Sensitive Repair different from other toothpastes: To defeat sensitivity you need to repair the damaged enamel and dentin surface. Thanks to microRepair®, Biorepair® toothpaste repairs tooth enamel by binding chemically to enamel and dentin, closing the tubules and preventing thermal stimuli from reaching the nerve of the tooth. It also prevents enamel erosion and the loss of natural tooth whiteness. Biorepair® Fast Sensitive Repair can be applied directly to the base of the affected tooth, massaging gently with your finger for 30 seconds. Rinse after use.
