Targeted help for sensitive teeth. Biorepair Fast Sensitive Repair toothpaste is designed for anyone struggling with unpleasant tooth sensitivity. Thanks to unique microRepair® microparticles, it repairs tooth enamel by chemically bonding to the enamel and dentin, sealing dentinal tubules and preventing thermal stimuli from reaching the tooth nerve. It also helps prevent enamel erosion and the loss of the teeth’s natural whiteness. The toothpaste formula is free from fluoride, parabens and SLS, making it an ideal choice even for the most sensitive mouths.
