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.

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.

Systems, devices, and methods are disclosed for maintaining oral hydration. A device may include a perforated tube, covered by an outer cover made of an absorbent material. The tube may be shaped such that it allows a patient using the device to open and close his or her jaw, without displacement and also to allow other medical devices to be used on the patient simultaneously.

An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.

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 device, method, and system are provided for aiding the whitening of teeth. 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 the upper teeth and surrounding gums and/or a layer over the lower teeth and surrounding gums, wherein each of the layers includes one or more hardened sections for enabling selected/differential collapsibility when exposed to vacuum pressure; and one or more treatment supply layers wherein the treatment supply layer incorporates a heating unit for heating treatment materials 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 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.

Mouthpieces for fitting inside a user's mouth and cleaning the teeth, tongue, gums and/or roof of the mouth are provided. The mouthpiece is a hands free toothbrush designed to fit inside the mouth and clean the teeth, tongue, gums and/or roof of the mouth. The mouthpiece is made up of flexible material and is sized to fit the user's mouth. It contains intricately designed tube structures. It will clean the user's mouth, teeth, tongue and gums. The mouthpiece slips in to the mouth and fits or approximates the contour of an individual's teeth. When not in use, the mouthpiece can be kept in its own container for sanitary purposes.

A whole-mouth dental hygiene apparatus includes first and second channel configured to fit over a user's entire teeth sets of the upper and lower jaw. The channels are aligned along a dividing wall and include rod-like projections extending from their surrounding walls into interiors of each channel, configured for scrubbing enamel and massaging gums through chewing action. The rod-like projections are formed of a molded silicon rubber material together with an entirety of the apparatus. The apparatus includes a handle for manipulating the apparatus attached to its exterior, positioned to protrude from a user's mouth when the apparatus is in use. The apparatus includes openings in the walls of each channel to allow for passage of fluid during use.

The present invention describes a conformable 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.
