Abstract
In some embodiments, an oral care device includes a flexible base substrate, a power source disposed on the base substrate, and first and second electrodes electrically connected to the power source. Also disclosed are methods of using the same, for example, for whitening the teeth or for treating other conditions in the oral cavity.
Claims29
An oral care device configured for placement in an oral cavity comprising:
- a flexible base substrate;
- a flexible power source disposed on a surface of the base substrate;
- and
- an electrode layer disposed on the surface of the flexible base substrate or the flexible power source, the electrode layer comprising an electrode substrate, a first electrode comprising a first flexible metallic strip electrically connected to the flexible power source, and a second electrode comprising a second flexible metallic strip electrically connected to the flexible power source, wherein the first and second electrodes are located on a first side of the electrode substrate and the flexible power source is located on an opposite second side of the electrode substrate;
- wherein the first and second electrodes have a polarity which is alternated during use.
