Which type of fluoride is in Sensodyne-F toothpastes, and what is its concentration?
All Sensodyne-F toothpastes contain sodium fluoride, the majority at a level of 0.243% by weight (Sensodyne-F Gel contains sodium fluoride at a level of 0.24% by weight). The role of fluoride in the formulations is for ongoing caries prevention. The sensitivity relief ingredient in Sensodyne toothpaste is either potassium nitrate (in all Sensodyne-F formulations) or strontium chloride (in the Sensodyne Original formulation).
