Various apparatus and methods for cleaning teeth and gingival pockets are disclosed herein. A fluid platform can include a pressure wave generator configured to propagate pressure waves through a treatment fluid. The pressure waves may be sufficient to remove undesirable dental deposits from a treatment tooth, neighboring gums, and/or spaces between the tooth and gums.

Oral hygiene systems and methods for their use are provided. An oral hygiene system includes a mouthpiece having an outer portion and an inner portion configured to receive at least a portion of a user's dental and gum structures, a plurality of filaments disposed within the inner portion of the mouthpiece, a water pressure irrigator configured to be selectively coupled to the outer portion of the mouthpiece and to deliver fluid to the inner portion of the mouthpiece, and a fluid reservoir in fluid communication with the water pressure irrigator and configured to deliver the fluid thereto, wherein the system is configured to generate ultrasound/ultrasonic vibration within the inner portion of the mouthpiece.

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 insert includes a plurality of bristles and a plurality of fluid nozzles. The plurality of bristles is located on an upper portion and a lower portion of a tray surface of the oral insert. The plurality of fluid nozzles is located at an inner portion and an outer portion of the tray surface. Fluid output by the plurality of fluid nozzles causes the plurality of bristles to contact surfaces of teeth associated with a user of the oral insert.

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 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.

Tooth-whitening device (10) includes discharger (22) configured to generate a tooth-whitening fluid by applying electric discharge to carbon dioxide gas, feeder (25) configured to supply the carbon dioxide gas to the discharger, humidifier (23) configured to generate humidified gas, outlet (40) provided with a supply port through which the tooth-whitening fluid is supplied into an oral cavity, and hollow part (30) configured to guide to outlet (40) a gas containing the tooth-whitening fluid generated by discharger (22).

Tooth-whitening device includes generator that generates a tooth-whitening fluid, neckband provided with generator, outlet provided with supply port through which the tooth-whitening fluid is supplied into an oral cavity, and hollow part that guides a gas containing the tooth-whitening fluid generated by generator to outlet. For example, outlet is a mouthpiece, and hollow part is a hose.

A 7-way dental syringe is a device in a dental delivery system that delivers an air stream, water stream, air spray and water spray; four efficient ways to clean a patient's mouth. Additionally, the 7-way dental syringe is a controllable pressurized dental water jet system. It can dislodge plaque biofilms from teeth and interdental regions, access a periodontal pocket to wash out plaque therein, and cleanse a tooth extraction site or irrigate exposed jawbone; various clinical ways to perform advanced oral hygiene.

Disclosed are improved apparatus, structures and methods for tooth cleaning using mouthpiece appliance(s), water jets, brushes, and sonics/ultrasonics as shown and described.
