A method for providing a beneficial effect to an oral cavity of a mammal, the method including contacting a plurality of surfaces of the oral cavity with a liquid effective for providing the beneficial effect to the oral cavity and providing reciprocation of the liquid over the plurality of surfaces of the oral cavity under conditions effective to provide the beneficial effect.

A tooth bleaching device provided with: a production device that produces an active component for bleaching a tooth; a mouthpiece in which a supply opening, through which the active component produced by the production device is supplied inside the oral cavity, is formed; and a connecting part that connects the production device and the mouthpiece.

An apparatus may include one or more manifolds, each including a shell having an inner portion and an outer portion. Each shell may have a first set of outlets in a first wall and a second set of outlets in a second wall that approximately faces the first wall. Each manifold is shaped to accommodate a tooth. A rotating inlet joint, having an inlet channel and a rotating joint, may enable fluid flow into each manifold from the inlet channel at any angle relative to an axis of rotation defined by the rotating joint. In each manifold, the first set of outlets and the second set of outlets are oriented towards a tooth and/or gums associated with the tooth. The inner portion and the outer portion of each shell cooperate to direct fluid flow substantially horizontal to, and then substantially perpendicular to, the fluid flow exiting the inlet channel.

An intraoral dental irrigation appliance is provided. The device can serve as a dual-purpose occlusal guard and irrigation device. The appliance can protect the teeth of the user from the damage caused by bruxism and even provide the user the ability to effectively irrigate some or all difficult areas of dentition. The appliance includes at least one port configured to receive an irrigation fluid, or irrigant. This port may attach to a fluid source like a tap, water irrigation device, or other moving fluid supply.

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.

An oral care device for providing oral-cavity information to a user or a manager includes: a liquid supply unit; a mouthpiece connected to the liquid supply unit and including a spatial portion configured to accommodate at least one of an upper tooth side and a lower tooth side when the mouthpiece is inserted into an oral cavity; a pump connected to the mouthpiece and configured to suction liquid from the liquid supply unit and introduce the liquid into the spatial portion and to suction fluid from the spatial portion; a storage unit connected to the pump and configured to store or discharge fluid suctioned from the spatial portion; and a measuring unit connected to the storage unit and configured to measure a state of fluid stored in the storage unit, wherein liquid is introduced to the spatial portion from the liquid supply unit only by suction force of the pump.

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.

A tooth arch receiving element has an arch formed of a conformable structure for receiving the teeth of a user. An actuator is used to increase the rigidity of the conformable structure after it has been shaped to correspond to a shape of a tooth arch of a subject during an arch fitting stage.

The present invention provides for oral care systems comprising: an appliance comprising a first and second plurality of nozzles, the appliance configured to be held in the mouth of a user with the first and second plurality of nozzles in fluid communication with one or more surfaces of the user's oral cavity; a source of gas; a source of liquid; and a fluid controller for directing entrained fluid to the appliance. Also provided are methods of cleaning, or otherwise providing oral care benefits to, one or more surfaces of the oral cavity using a system of the present invention.
