Abstract: An oral irrigation device including a reservoir, a tip, and a pump. The pump is operative to draw fluid from the reservoir and propel the fluid to the tip. The pump includes a pump body fluidly connected to the reservoir and the tip, the pump body having an interior wall defining a pump chamber, the pump chamber terminating in an open end and a force exerting assembly that is receive within the pump chamber. The force exerting assembly is movable between a first position and a second position and includes a force exerting member and a compressible sealing member received around the force exerting member. The sealing member engages the interior wall of the pump body during movement from the first position to the second position and movement from the second position to the first position to prevent fluids from escaping the open end of the pump body.

Abstract: A closed system mouthpiece uses light and heat generation to activate a gel formulation to increase its volume. The gel formulation is coated into the mouthpiece, which is inserted into the user's mouth. Application of heat above a threshold temperature causes the gel to transform into foam and expand out of the mouthpiece and into the oral cavity. The mouthpiece creates a hermetic seal such that the foam expands out throughout the oral cavity into nooks and crannies that are normally difficult to access. Activation of a light source embedded within the mouthpiece enhances the bacteria killing properties of the foam material. The pH balance of the mouth is restored by the inventive method and apparatus to a neutral level in the range of 6.75 to 7.25.

Abstract: The interproximal toothbrush includes an appliance body and neck with a nozzle member having a nozzle tip shaped to fit into interproximal teeth spaces. Bursts of air or air/liquid mixture are generated, exiting through the nozzle tip. A helix member or, alternatively, a spring, is supported within a channel in the nozzle member. The helix member is free to rotate as air or the air/liquid mixture is moved through the channel. A set of bristles is attached to a forward end of the helix member, so that it rotates with the helix member. Alternatively, a set of bristles is attached to the distal end of the spring so that successive bursts of air or the air/liquid mixture produce an in-and-out movement of the set of bristles toward and away from the teeth.
