Anhydrous stannous fluoride toothpaste beats sensitivity pain fast

The anhydrous formulation works rapidly to form a barrier over exposed dentine and reduce sensitivity in just 60 seconds. The new formulation builds ongoing protection with every brush, supporting the long-term management of dentine hypersensitivity, a painful, chronic condition affecting as many as one in three people.

The use of GSK Consumer Healthcare’s proprietary anhydrous formulation technology means that individual ingredients contained in the formulation, including stannous fluoride and bio-adhesive polymers, remain stable and ready for activation by water. On contact with saliva in the mouth, the facilitating polymer becomes adhesive, and is able to form a gel-like scaffold in the surface of dentine, helping to trap stannous ions which occlude the open ends of the dentine tubules. In vitrodata shows that after just one application, stannous ions, the key sensitivity active ingredient in new Sensodyne Rapid Relief, can extend as much as 80μm deep into the tubules, providing rapid occlusion and a 127 per cent reduction in the flow of fluid through the dentine tubules, compared to the previous stannous fluoride formulation. This robust occlusion is resistant to exposure to dietary acids, leading to clinically proven fast and long-lasting relief from the pain of dentine hypersensitivity.
