Sensodyne Science: Stannous Fluoride Formulation
The Sensodyne Rapid Relief stannous fluoride formulation occludes exposed dentin tubules, helping prevent the movement of fluid1,3-5
Representative FIB-SEM image of dentin tubules treated with Sensodyne Rapid Relief, combining multiple imaging techniques (STEM-EDS, DSIMS, FIB-SEM/EDS). The stannous fluoride formulation is shown to extend into the dentin tubules.4,5

- The non-aqueous formulation ensures stannous fluoride becomes active when in contact with saliva
- The stannous fluoride formulation becomes activated in saliva, sticking to dentin and tooth structure
In this study, Sensodyne Rapid Relief stannous fluoride formulation with inactive polymer, has been shown to reduce fluid flow through dentin tubules as compared to a regular stannous fluoride toothpaste after one application in vitro.*1

SnF2, stannous fluoride
*vs. another toothpaste containing 0.454% stannous fluoride. Although the active ingredients are the same, the way the toothpastes are formulated affects the way they work.1 A four-day hydraulic conductance study measuring the fluid flow rates through dentin tubules of two toothpaste formulations. Fluid flow rates were measured after the initial treatment and on Days 1–4. The Pashley hydraulic conductance model and Earles’ solution passed through dentin tubules when a simulation of pulpal pressure was used
Sensodyne Rapid Relief with stannous fluoride is clinically proven to relieve sensitivity from the first brush.6

'Dab-on' refers to direct application with finger to sensitive teeth.
Two additional studies have been conducted: GSK data on file 205072 showing 14% reduction in Schiff score from baseline after a single application, and GSK data on file 207212 showing 29% reduction in Schiff score from baseline after a single application.
A continued reduction in dentin hypersensitivity has been shown after 8 weeks of brushing with Sensodyne Rapid Relief.10 It provides long-lasting protection from sensitivity with twice daily brushing.
