Sensodyne: Stannous Fluoride Science

Stannous fluoride formulation accelerates occlusion of exposed dentine tubules

The facilitating polymer becomes adhesive in saliva, sticking to dentine and helping to trap stannous ions inside.1

Study summary

Clinical summary

Clinically proven fast relief6–8

  • Anhydrous formulation 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
  • Fluid flow occlusion

    Sensodyne Rapid Relief 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

    Study summary

  • Relief after first brush

    Sensodyne Rapid Relief with stannous fluoride and bio-adhesive polymer is clinically proven to relieve sensitivity from the first brush.6

    Chart adapted from GSK data on file 2072116Two 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 brush6

    Clinical summary

  • Relief after ‘dab-on’

    Sensodyne Rapid Relief 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

    Clinical summary

  • Hypersensitivity relief after long-term use

    A 63% reduction in dentine hypersensitivity has been shown after 8 weeks of brushing with Sensodyne Rapid Relief.10
