How does Sensodyne iso-active work?

NEW Sensodyne iso-active is an innovation in toothpaste technology.

iso-active foaming gel is a novel delivery system that disperses active ingredients quickly throughout your mouth.

The technological innovation behind the gel-to-foam formula of Sensodyne iso-active is the inclusion of isopentane. During brushing, isopentane is activated by the heat of your mouth, rapidly transforming the iso-active gel into a microfine foam. With twice the foam of regular toothpaste, Sensodyne iso-active penetrates hard to reach areas deep between teeth and along the gum line to provide all around sensitivity protection and cleaning.
