A teeth cleaning system, which provides improved coverage or brushing area. The system includes an actuated tray comprises brushing elements. The brushing elements may be positioned to engage the front, rear, and top surfaces of the upper and lower jaw teeth. The actuation may be configured to oscillate the tray in a lateral direction which may brush all the surfaces of teeth simultaneously. Some embodiments include a higher density of bristles which increases the effectiveness of brushing. In addition, aspects of the system reduce the time spent brushing teeth.

In one embodiment, the invention may be a teeth cleaning device including: a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user; a plurality of teeth cleaning pads located within the first dentature channel; a plurality of air bladders operably coupled to the teeth cleaning pads; an air-flow subsystem operably coupled to the air bladders; and a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode.

An oral cavity treatment device including a power component and a tray component that are detachably coupled together. The power component may include a housing having a cavity and a power source located therein. The tray component may include a tooth receiving channel and may have a first electrode and a second electrode located on opposite sides of the tooth receiving channel. The tray component may be detachably coupled to the power component in: (1) a first configuration whereby the first electrode is operably coupled to a positive terminal of the power source and the second electrode is operably coupled to a negative terminal of the power source; and (2) a second configuration whereby the first electrode is operably coupled to the negative terminal of the power source and the second electrode is operably coupled to the positive terminal of the power source.

A connecting element, a base unit and a cleaning head for use in an oral care appliance are disclosed. The connecting element is configured to engage operatively with the cleaning head and the base unit to form a first connection and a second connection respectively.

The invention relates to a dentifrice dispenser for dispensing a dentifrice onto a J-shaped or U-shaped mouthpiece configured for simultaneously encompassing and cleaning a plurality of dental positions with the dispensed dentifrice and with cleaning elements provided on or in the mouthpiece. The dispenser comprises a dispenser duct work having an inlet and a manifold. The manifold comprises a multiple of outlet openings configured for dispensing dentifrice. The duct work is configured for passing dentifrice from the inlet to the outlet openings. The outlet openings are distributed along a J-shaped or U-shaped curvature and debouch towards and/or along the curvature, which matches at least part of a dental arch such that the outlet openings can dispense dentifrice simultaneously on a multiple of locations along the curvature, the multiple of locations corresponding to the multiple of outlet openings.

A wear-out assessment for an oral care system (14) (e.g. an oral cleaning device) is disclosed. A sensor unit (16) of the oral care system is adapted to provide a sensor signal related to a cleaning efficacy of a cleaning function of the oral care system. The sensor unit (16) may be, or may be coupled to, a component which is used during execution of an oral care function of the device, for example a sensor for detecting cleaning progress in the mouth, or a component which drives a cleaning or treatment action in the mouth. The sensor signal (20) is used for performing a wear-out assessment via monitoring characteristics of a signal which is indicative of progress of the oral cleaning efficacy during an operation session (e.g. a clean level in the mouth) and monitoring a length of time that it takes for a certain threshold of efficacy to be reached in a session. If the length of time is over a certain threshold, this can be an indication that the relevant components of the oral care system are wearing out.

A plasma treatment device configured for a treatment within the oral cavity of a living organism using a dielectric barrier plasma, comprising a high-voltage stage (5, 6) arranged in a housing and serving for generating high-voltage signals required for generating the plasma, and comprising an electrode arrangement (10), which is connected to the high-voltage stage and is covered by a dielectric (9) for forming a dielectric barrier plasma, enables various treatments in the oral cavity of the living organism in a simple manner by virtue of the fact that the housing has a handle part (1), to which a head part (2) is secured in a releasable and exchangeable manner by means of a mechanical connection arrangement, in that the handle part (1) contains all stages required for generating the high-voltage signals and a contact arrangement, at which the high-voltage signals are present, in that the head part (2) is embodied in a shape specific to a specific treatment and has a corresponding shaped electrode arrangement (10), which is surrounded completely by the dielectric (9) and has a terminal (14), which makes contact with the contact arrangement of the handle part (1) when the head part (2) is secured to the handle part (1) in a manner effected by means of the mechanical connection arrangement.

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 method and an apparatus are disclosed for simultaneously cleaning multiple teeth, such as one or both dental arches. The Dental Cleaning Apparatus (DCA) includes a cleaning engine enclosed in a main housing, a fluid tube, and a mouthpiece. The cleaning engine includes a fluid circuit having a number of pumps and solenoid valves, and a programmable controller to control the solenoid valves and other operations. The fluid tube includes a number of separate tubes for injection and evacuation of cleaning fluid from the interior of mouthpiece. The mouthpiece is generally made from a flexible and supple material, such as silicone, and may have bristles of various shapes. The cleaning engine alternates the mouthpiece between a relaxation state and a contraction state to effectively scrub the surface of all enclosed teeth simultaneously. It may automatically learn and adjust the vacuum pressure needed for each user to optimize cleaning.
