Abstract
A new method and a system for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The device includes a dispensing unit for the composition, a distal end of which is adapted to apply the composition onto teeth or gums. The device further includes an electrode system having first and second electrodes, the first electrode adapted to be held against the composition at a location at or near teeth or gums, and the second electrode adapted to be held against the composition at a location away from teeth or gums. The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the first and second electrodes.
