Sensodyne Rapid Action contains strontium which acts to create a mineral-like seal over the surface of the dentine and within the microscopic channels. This prevents stimulus from reaching the nerve. Twice daily brushing provides long lasting protection from sensitivity. Also the fluoride helps to protect and strengthen teeth.
