Delivers clinically proven relief from the pain of dentine hypersensitivity br proven resistance of reparative layer to daily oral challenges br contains novamin174 which builds a protect layer over exposed dentine br employs the same bioactive material used in advanced bone regeneration research br br br sensitivity occurs when the dentine underneath tooth enamel becomes exposed. When exposed dentine comes into contact with hot or cold, sweet, sour or even your toothbrush it can trigger the nerve, causing a short sharp pain. Traditional desensitising toothpastes deal with sensitivity simply by treating the pain. Sensodyne repair and protect is different.
