Stannous fluoride formulation
Sensodyne Rapid Action is specially formulated with stannous fluoride
Engineered for speed: stannous fluoride formulation with bio-adhesive polymer gives fast relief from dentine hypersensitvity.1,2
Stannous fluoride formulation accelerates occlusion of exposed dentine tubules
The unique formulation – with a balance of active stannous fluoride and bio-adhesive polymer – accelerates occlusion of dentine tubules by:1
- Providing improved bio-adhesion*3
- Forming a gel-like scaffold to hold the stannous in place1
*vs. toothpaste containing 0.454% stannous fluoride and lower polymer level
The Sensodyne Rapid Action stannous fluoride formulation occludes exposed dentine tubules, helping prevent the movement of fluid1,3–5

-
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 facilitating polymer becomes adhesive in saliva, sticking to dentine and helping to trap stannous ions

Engineered for speed – a unique formulation that accelerates occlusion of exposed dentine tubules1
Sensodyne Rapid Action has a unique formulation of stannous fluoride with facilitating bio-adhesive polymer, and has been shown to reduce fluid flow through dentine tubules by 127% compared with a regular stannous fluoride toothpaste after one application in vitro.*1

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 dentine 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 dentine tubules when a simulation of pulpal pressure was used

Reduction in dentine hypersensitivity after a single ‘dab-on’ application8
Sensodyne Rapid Action with stannous fluoride and bio-adhesive polymer is clinically proven to relieve sensitivity in just 60 seconds.8
Chart adapted from Seong et al. 20178'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
