An oral irrigator has a separate high pressure water system and low pressure mouth rinse system to deliver two different fluids to a pick or other accessories. The water system and mouth rinse system are combined in a handle. The pick is connected to the handle. The water system has a blocking valve located in the handle and the mouth rinse system has a hand pump located in the handle. The hand pump sits next to a valve button for closing the blocking valve. When the hand pump is pressed, it presses against the valve button of the blocking valve to shut off the source of high pressure water to the pick. The pressure in the pick drops so that the hand pump can then introduce mouth rinse into the pick. When the hand pump is released, the blocking valve opens up and high pressure water returns to the pick.

A teeth whitening device includes a generator configured to generate a teeth whitening fluid that whitens teeth and humidified gas, a mouthpiece configured to supply the teeth whitening fluid and the humidified gas, and a coupling part that couples the generator and the mouthpiece with each other. The mouthpiece includes a first supply port through which the teeth whitening fluid is supplied, and a second supply port through which the humidified gas is supplied, the second supply port being separated from the first supply port. The mouthpiece further includes a first supply passage configured to guide the teeth whitening fluid to the first supply port, and a second supply passage configured to guide the humidified gas to the second supply port, the second supply passage being separated from the first supply passage.

The present invention provides a high-pressure-water toothbrush and a U-shaped jet-washing groove structure thereof, comprising: a handle and a U-shaped jet-washing groove provided at an end of the handle. The U-shaped jet-washing groove structure has a first sidewall and a second sidewall facing the first sidewall, and each of the first sidewall and the second sidewall has an inner wall surface provided with a plurality of nozzles. By the implementation of the present invention, the insides and outsides of the teeth surfaces and teeth gaps can be simultaneously flush for the purpose of quick and effective to cleaning the teeth.

Devices for collecting a fluid sample from the oral cavity, the device including a mouthpiece that includes a chamber, the chamber including front and rear inner walls; and means for collecting the fluid sample from the oral cavity; and methods of collecting and analyzing samples of fluid from the oral cavity, including the steps of placing the device in the oral cavity, collecting the fluid sample and conducting an analysis of the fluid sample.

A custom dental irrigation device has: a user dentition model; a custom made mouthpiece made according to the user dentition model, a pump configured to pump fluid to the mouthpiece; a suction pump configured to remove fluid from the mouthpiece; a fluid tank; and a controller. The custom made mouthpiece is configured to deliver fluid to the dental target while removing used irrigation fluid. The mouthpiece is fabricated with 3-D print techniques. The mouthpiece is designed in two pieces to cover an upper portion of a dental target and a lower portion of a dental target separately. The mouthpiece has an inner surface following the shape of the user dentition model, wherein the inner surface touches the gingiva tissue to form a sealed space once the mouthpiece is set in a user's mouth, whereby fluid is delivered to the dental target, and removed from the sealed space.

Disclosed are devices, systems and methods for treating periodontal disease and/or other oral wounds using particularized oral appliances and associated negative pressure systems. The various oral appliances include one or a plurality of surfaces for engagement with various anatomical structures within the oral cavity, where the engagement can include sealing engagement with soft tissue (gingival) surfaces of the upper and/or lower dental arches. Additional features disclosed can further promote healing of regions affected by periodontal pocket formation.

Embodiments are described wherein a system for brushing the teeth of a person comprises a master input device; a flexible teeth tray configured to at least partially encapsulate one or more of the teeth in a flexible substrate material, the flexible teeth tray comprising one or more vibratory transducers removably coupled to one or more brushing panels; and a controller operatively coupled to the master input device and the one or more vibratory transducers; wherein subject to an input from the master input device, the controller is configured to cause reciprocating brushing motion of the one or more brushing panels against a surface of the one or more encapsulated teeth, to clean the one or more teeth.

An oral cavity cleaner according to an exemplary embodiment of the present disclosure includes: a handle including an inflow path through which washing water flows and a discharge flow path through which contaminated water sucked from an oral cavity flows; a mouthpiece connected to the inflow path and configured to spray the washing water into the oral cavity; a core suction part configured to suck the contaminated water that has been discharged from the mouthpiece and washed teeth; and a suction pipe in which the contaminated water flows, the suction pipe being disposed in the mouthpiece and configured to connect the core suction part and the handle.

A device for and method of delivering a therapeutic fluid to the oral cavity of a user. The device includes a source of pressurized therapeutic fluid and a mouthpiece. The mouthpiece has a posterior facing end, and a body having a first surface for enabling the user's lips to seal the oral cavity from an external environment when the mouthpiece is received in the oral cavity. The mouthpiece comprises an inlet passageway and an outlet passageway extending through the body and in fluid communication with the posterior facing end, wherein the inlet passageway delivers a therapeutic fluid under pressure to the oral cavity and the outlet passageway enables egress of the therapeutic fluid from the oral cavity. The device can also include a reservoir for receiving saliva generated by the user that may be recirculated along with the therapeutic fluid to the oral cavity.

An oral care system for cleaning teeth and gums includes a housing, an oral hygiene unit, and a gooseneck arm attached to the housing and releasably coupling the oral hygiene unit to the housing, the gooseneck arm being adjustable to hold the oral hygiene unit at a defined position and orientation relative to the housing. The oral hygiene unit has a mouthpiece having at least one arcuate channel adapted to receive and surround the teeth. The mouthpiece includes at least two modalities chosen from a group consisting of a mechanical modality, an iontophoretic modality, and a disinfection modality, wherein the mechanical modality brushes the teeth and gums and dislodges food debris, the iontophoretic modality breaks up plaque buildup, and the disinfection modality removes the food debris and plaque. The oral care system includes a control unit which controls transmission of the modalities and tracks utilization of the system.
