Abstract: One embodiment of the invention comprises an oral care system that comprises a photocatalytic solution. The photocatalytic solution may comprise titanium oxide nanotubes. The system may also include an oral instrument that is coupled to a light source. The photocatalytic solution will degrade oral pollutants upon exposure to illumination from the light source. The photocatalytic solution may be disposed, for example, within, on or about a dentifrice. The titanium oxide nanotubes may be rectangular in cross-section, anatase in form and less than 500 nm in width, less than 500 nm in length, and less than 5000 nm in height.
