An oral cavity cleaner according to the present disclosure includes: a handle including an inflow path through which washing water flows; and a mouthpiece having spray holes for spraying the washing water into an oral cavity, in which the mouthpiece includes: a labial surface corresponding portion formed at a position facing labial surfaces of teeth; a buccal surface corresponding portion connected to the labial surface corresponding portion and formed at a position facing buccal surfaces of the teeth; a lingual surface corresponding portion formed at a position facing lingual surfaces of the teeth; and an intermediation portion configured to connect the labial surface corresponding portion and the lingual surface corresponding portion and having two opposite ends starting from a connection point between the labial surface corresponding portion and the lingual surface corresponding portion.

This disclosure relates to an oral care appliance and a method for use in oral care for cleaning the teeth of one or two arches using a mouthpiece forming a closed or nearly closed cavity. The mouthpiece is adapted to deform in response to pressure variations inside the cavity and create an action on the teeth. This disclosure includes a description of depression chambers and associated methods that can contribute to the operation of the oral care appliance by affecting the aforementioned pressure variations.

An oral irrigator system having an ergonomic casing with a pliable nozzle assembly, and coupled to a detachable and refillable fluid reservoir. The ergonomic casing contains a power source and a pump mechanism. The detachable nozzle head delivers a pulsating jet of fluid with adjustable speed into the oropharyngeal cavity. When the system is turned on, the rechargeable battery activates the diaphragm pump to draw fluid from the reservoir using a fluid pipe and delivers the fluid to the tip of the nozzle head.

Designing personalized oral irrigation may include a generated oral insert including a fluid inlet port, fluid nozzles, manifolds, and a tray configured to retain teeth. One variation of a design method may comprise the steps of displaying a graphical representation of the oral insert model, generating a geometry of the fluid nozzles based on oral scan data of a jaw, defining a tray surface that encloses the fluid nozzles based on the oral scan data, and generating a geometry of the manifolds that connect the fluid inlet port to the fluid nozzles on the graphical representation of the oral insert model. The manifolds are configured to provide a predetermined range of hydraulic pressures to each of the fluid nozzles.

The present invention describes a method for a U-shaped teeth brush device having a conformable shape adjusting U-shaped teethbrush module and one or more individual tooth brushes coupled to the power drive mechanism, each brush having a sensor, piezoelectric crystal and transducer and each tooth brush having a block anchor coupled to the power drive, under smart controls, an electronic control system for sensing individual tooth pressure and controlling motor transmission of vibration to prior positioned brushes, whereby a users unique mouth features can be accounted for by adjusting U-shape distal ends to fit through the users mouth and align with users teeth arch for programmatically brushing more than one tooth simultaneously.

A micro-scale mist teeth cleaning device includes console creating air under pressure and water under pressure. The console is connected to a mouthguard that is in the form of an outer ridge and an inner ridge with space in between for the teeth of a patient. The mouthguard includes a receptor for receiving the air and water under pressure, and has tubes for separately distributing the air under pressure and the water under pressure along the outer and inner ridges. The mouthguard further includes openings along the inner side of the outer ridge and the outer side of the inner ridge facing the location of the patient’s teeth when the mouthguard is installed in the patient’s mouth. The tubes for the pressurized air and the water intersect at each opening at an angle such that they act to eject a micro-scale mist from the opening onto the user’s teeth, thereby providing initial dental plaque removal.

Described herein are systems and methods for providing personalized oral irrigation. One variation of a system for personalized oral irrigation comprises a fluid reservoir and a customized oral insert in fluid communication with the fluid reservoir. The oral insert comprises an arrangement of fluid openings positioned based on the individual oral or dental structures of a user's teeth to provide a customized fluid flow over the user's teeth. Also described herein are methods for generating an arrangement of fluid openings in a customized oral insert.

A device, method, and system are provided for treating the oral cavity. The device includes a mouthpiece suitable for implementing a dental treatment, wherein the mouthpiece includes one or more stock elastomeric dental cover layers suitable for forming and maintaining a treatment cavity having a vacuum fluid seal, wherein the dental cover layers includes a layer over all the surfaces of the upper teeth and surrounding gums and/or a layer over all the surfaces of the lower teeth and surrounding gums, wherein each of the layers includes one or more hardened rigid or semi-rigid sections for enabling selected and/or differential collapsibility of the cover layers when exposed to vacuum pressure; and one or more treatment supply layers, and one or more flow channels in fluid communication with the treatment cavity so that the treatment supply layer can deliver and/or remove one or more treatment fluids from the one or more fluid sealed treatment cavities.

An oral insert includes a plurality of manifolds and a plurality of fluid nozzles. A manifold switch is coupled to the plurality of manifolds. The manifold switch is configured to select which of the plurality manifolds is to receive fluid from a fluid source.
