Brush that delivers beneficial agents

A device for supplying an oxidizing agent for topical treatment of an oral surface, said device comprising:

• a toothbrush of the type having a stem and bristles associated therewith, said bristles being oriented for application to a subject's oral surface, and
• an oxidizing agent generator incorporated within the toothbrush stem for supplying an oxidizing agent to the bristles for application to the oral surface wherein the oxidizing agent generator generates oxygen electrochemically, and includes:
• a cathode for reducing oxygen in a feed gas to negative ions, neutral species, or mixtures thereof;
• an electrolyte for transporting the ions, neutral species or mixtures thereof therethrough;
• and
• an anode communicating with the electrolyte for oxidizing the negative ions, neutral species or mixtures thereof to produce an oxygen gas for supply to the oral surface upon actuation of electrical circuitry operably associating said cathode, anode, and electrolyte.

A brush comprising:

• a stem having a first end and a second end, said first end serving as a handle;
• bristles associated with said second end of said stem;
• and
• a beneficial agent generator for delivering a beneficial agent to said bristles, said beneficial agent generator associated with said stem, and in fluid communication with at least a portion of said bristles wherein said beneficial agent generator comprises a photoelectrochemical cell, a battery, and a switch, the photoelectrochemical cell comprising a light source having a wavelength greater than 180 nanometers, and a catalyst layer, said battery and photoelectrochemical cell encased within said stem.

A brush comprising:

• a stem having a first end and a second end, said first end serving as a handle;
• bristles associated with said second end of said stem;
• and
• a beneficial agent generator for delivering a beneficial agent to said bristles, said beneficial agent generator associated with said stem, and in fluid communication with at least a portion of said bristles wherein said beneficial agent generator is an oxidizing gas generating cell encased within said stem.

A method of treating a tooth's surface comprising:

• providing a toothbrush comprising:
• a stem having first and second ends said first end serving as a handle, bristles associated with said second end of said stem,
• means for generating a fluid comprising an oxidizing agent, said means associated with said stem, and
• an actuator operably associated with said means for generating a fluid;
• actuating said actuator and
• brushing said tooth surface with said bristles for a period of time
• wherein said means for generating a fluid comprising an oxidizing agent is a gas generating cell partially encased within the second end of the stem associated with the bristles.
