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

Stannous fluoride is delivered in an anhydrous (non-aqueous) formulation that is primed to react in the mouth
- 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
A stannous fluoride formulation that has been engineered for speed
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

*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

Reduction in dentine hypersensitivity after brushing sensitive areas8
Sensodyne Rapid Relief with stannous fluoride is clinically proven to relieve sensitivity from the first brush.6

Two additional studies have been conducted: GSK data on file 205710 showing 7% reduction in Schiff score from baseline after first brush, and GSK data on file 205697 showing 18% reduction in Schiff score from baseline after first brush9
Reduction in dentine hypersensitivity after a single ‘dab-on’ application8
Sensodyne Rapid Relief with stannous fluoride is clinically proven to relieve sensitivity in just 60 seconds.8

'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.
Sensitivity relief that continues to improve with twice-daily use7
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.

Sensodyne Rapid Relief toothpaste
Sensodyne Rapid Relief toothpaste is engineered for speed.1,2 It is powered by stannous fluoride in a formulation that accelerates occlusion of exposed dentine tubules, providing sensitivity relief in just 60 seconds.10*
