Patent ID: 8241035

Claim:
A device for treating oral tissue, comprising: a carrier constructed to be applied in proximity to at least one oral tissue within a mouth; an activated textured surface coupled to the carrier and comprising first and second sets of members constructed for being activated and moved in different ways thereby to impart different repetitive movements to the first and second sets of members and further to impart electromagnetic radiation, from at least a first electromagnetic radiation source and a second electromagnetic radiation source having a different wavelength, to the oral tissue; and a dentifrice disposed on the activated textured surface, the dentifrice having a first layer with a first active ingredient that is more sensitive to wavelengths from the first electromagnetic radiation source and a second active layer with a second ingredient that is more sensitive to wavelengths from the second electromagnetic radiation source; wherein the activated textured surface comprises (a) bristles of a first height and (b) bristles of a second greater height constructed to direct electromagnetic energy through the first layer and into the second layer; and wherein the device is a mouthtray and the activated textured surface comprises textured surfaces that are configured to be activated to automatically provide one or more of mechanical agitation and mechanical cleaning forces onto the oral tissue.
