A directed jet mouthpiece (10) comprises at least one mouthpiece trough (12, 14) configured to fit over a front portion of a dental arch of a user's teeth. The at least one mouthpiece trough includes a buccal-side vertical member (16), a lingual-side vertical member (18) and an occlusal-side horizontal member (20) extending in between. The at least one mouthpiece trough further includes at least one fluidics inlet (22), a plurality of jet orifices (24) on both buccal- and lingual-side vertical members, and at least one fluidics path (26) disposed between the fluidics inlet and jet orifices. A plurality of directed jet orifices (28) is disposed in end regions (30) of the at least one mouthpiece trough. The at least one fluidics path (26) is further disposed between the fluidics inlet and plurality of directed jet orifices. The plurality of directed jet orifices (28) direct fluid jets rearward towards a remainder of teeth in a user's mouth beyond the end regions (30) of the at least one mouthpiece trough.

A system for intraoral fluid delivery comprises a rate-controlled and/or volume-controlled fluid supply device, a reservoir for holding one or more fluids to be delivered to a patient's oral cavity, a mouthpiece to be worn by a patient at least partially within the patient's oral cavity, and tubing to carry the one or more fluids from the fluid supply device to the mouthpiece. The mouthpiece comprises a fluid inlet adjacent and/or exterior to the patient's oral cavity when the mouthpiece is worn by the patient, a fluid outlet posterior to the fluid inlet, and a fluid channel therebetween.

A disposable smart electronic teeth cleaning device for cleaning a plurality of teeth is provided. The disposable smart electronic teeth cleaning device includes a liquid pump, a pipe and an U-shaped main body. The liquid pump provides a cleaning liquid. The pipe is in communication with the liquid pump. The U-shaped main body includes a teeth-containing groove and a liquid inlet. The teeth-containing groove contains the plurality of teeth. The liquid inlet is disposed at the teeth-containing groove and is in communication with the pipe. The cleaning liquid provided by the liquid pump flows into the teeth-containing groove via the pipe and the liquid inlet to clean the plurality of teeth in the teeth-containing groove.

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.

A mouthpiece for a dental cleaning device comprises a supporting structure configured to encompass a plurality of teeth of a dental arch. The supporting structure has an inner surface facing a tooth surface. At least one brushing chamber is provided at the inner surface side. The brushing chamber comprises a flexible wall part being deformable by pressurizing or depressurizing the brushing chamber. Bristles extend externally from the flexible wall part. In a method of brushing teeth, a plurality of teeth is encompassed by the mouthpiece, and the at least one brushing chamber is alternatingly pressurized and depressurized.

A customized oral irrigator which is adapted to the user's dentition, has multiple nozzles or cutout openings to point to the area to irrigate. User can anchor such device by biting with the teeth and irrigate the teeth and gum, especially between the teeth and under the gum, in one instance. Such a device is fast and effective. It will be beneficial to everyone but will especially benefit busy professionals, children, seniors, handicapped, disabled, and other users who have difficulty cleaning teeth, for example people who wear dental devices such as braces. This device is meant to combine oral care procedures such as tooth brushing and dental flossing in one instance and will yield better dental hygiene and with better compliance than conventional brushing and flossing and conventional single channel oral irrigators.

An oral cavity washing device includes a nozzle and a pump that supplies a liquid to the nozzle. The nozzle has a nozzle flow passage and a reduced part that is disposed in an intermediate part of the nozzle flow passage and that is smaller in cross-sectional area than a rest of the nozzle flow passage. A first flow passage and a second flow passage that are in parallel to each other are disposed between the nozzle and the pump. The first flow passage has a first valve that causes the first flow passage to be opened only when the pump sucks the liquid. The second flow passage has a second valve that causes the second flow passage to be opened only during discharge performed by the pump.

An oral cavity cleaner according to an 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 configured to spray the washing water supplied through the handle into the oral cavity; and a core suction part having an edge surrounded by the mouthpiece, the core suction part being configured to suck the contaminated water that has been discharged from the mouthpiece and washed 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.

An oral cavity cleaner according to an embodiment of the present disclosure includes: a mouthpiece configured to spray washing water into an oral cavity; a core suction part configured to suck contaminated water, in which the washing water and saliva are mixed, from the inside of the oral cavity; and a handle including an inflow path through which the washing water flows, a discharge flow path through which the contaminated water flows, and a diffusion flow path configured to define a space in which the washing water flows in a direction toward at least one of upper and lower sides of the discharge flow path, the diffusion flow path being configured to supply the washing water to the mouthpiece.
