Tooth cleaning toothbrush and system

A toothbrush for use with a system for the removal of plaque and other unwanted debris from the teeth of a user, said system including a low pressure source of air, said toothbrush comprising

• a handle,
• a distal head,
• a multiplicity of bristles each comprising a shaft having a base associated with a surface of said head, said shaft extending away from said surface and having a proximal end disposed in relation to proximal ends of other said shafts for mutual engagement with teeth surfaces of a user, said multiplicity of bristles defining a multiplicity of interconnected restricted flow pathways therebetween,
• said multiplicity of bristles further adapted to receive a dispersion of liquid in said multiplicity of interconnected restricted flow pathways between said bristles to form a moist environment within said closed volume,
• said head surface defining an orifice surrounded by the bases of said bristles, and
• means defining a conduit having a distal end terminating in said orifice,
• said bristles, in combination with said surface of said head and said tooth surfaces, forming an enclosed volume,
• said conduit being arranged to receive a flow of air from said source at a proximal end of said conduit and to carry said air to said orifice, said orifice being arranged to direct said flow of air into the moist environment of said enclosed volume, said pathways within said enclosed volume being arranged to combine with flow of air with the liquid dispersed in said pathways between said bristles so as to form a multiplicity of small, air-containing bubbles, said pathways being further arranged to direct said air-containing bubbles along said pathway in the direction of said teeth surfaces, and means for draining said air-combining bubbles to burst with impulsive force against the engaged teeth surfaces in a manner to remove plaque and other debris from the teeth surfaces.

• said surface of said head defining an orifice surrounded by the bases of said bristles,
• means defining a conduit having a distal end terminating in said orifice,
• said bristles, in combination with said surface of said head and said tooth surfaces, forming an enclosed volume containing said orifice and said multiplicity of bristles,
• a source of low pressure air associated with the proximal end of said conduit for supplying a flow of low pressure air through said conduit and said orifice into said enclosed volume, said source comprising
• a low pressure source of air, and
• a tube connecting said source to said proximal end of said conduit, and
• a sealed chamber containing said liquid and connected to said tube,
• means for dispersing liquid in said multiplicity of interconnected restricted flow passageways between said bristles to form a moist environment within said closed volume,
• means for delivering said flow of air from said orifice to combine with the liquid dispersed in said pathways between said bristles in a manner to form a multiplicity of small, air-containing bubbles within said pathways, and
• means for directing said air-containing bubbles along said pathways, and means for driving said air-containing bubbles to burst with impulsive force against the engaged teeth surfaces in a manner to remove plaque and other debris from said teeth surfaces.
