Sensodyne Whitening with iso-active technology works in a similar way to Sensodyne Multi-Action, but it also improves the colour of teeth and restores natural whiteness by breaking downs stains on the surfaces of the teeth; it is purchasable in the UK and US.
The iso-active technology converts the gel formula into a foam, which spread around the mouth, washing away traces of bacteria from the whole of the mouth, even the hard-to-reach places. Cleaning with this foam toothpaste is much more thorough than with other types of toothpaste, as more traces of bacteria are removed; this helps to reduce the risk of decay and keeps the gums healthy.
Sensodyne Whitening should be used in the same way as other toothpastes; dentists recommend that patients brush their teeth at least twice each day. Using Sensodyne Whitening toothpaste will keep the breath smelling fresh, reduce the risk of tooth decay and cavities, keep gums healthy and relieve any pain caused by having sensitive teeth.
