Abstract
Abstract A system for the removal of plaque and other unwanted debris from the teeth of a user includes a toothbrush having a handle, a distal head, and a multiplicity of bristles. Each bristle includes a shaft having a base associated with a surface of the head, the shaft extending away from the surface and terminating in a proximal end disposed in relation to proximal ends of other shafts for mutual engagement with teeth surfaces of a user. The multiplicity of bristles define between themselves a multiplicity of interconnected restricted flow pathways. The surface of the head defines an orifice surrounded by the bases of the bristles. A conduit has a distal end terminating in the orifice. The bristles, in combination with the surface of the proximal end of the conduit supplies a flow of low pressure air through the conduit and the orifice into the enclosed volume,the flow of air from the orifice combining with a liquid dispersed in the pathways between the bristles so as to form a multiplicity of small bubbles within the pathways. The bubbles are directed by the orifice and driven by the air flow along the pathways and impact against the engaged teeth surfaces and burst to remove plaque and other debris from the teeth surfaces.
