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.

Various embodiments are provided herein for a medical device that has: a suction element with an elongated arm for placement between a check and the upper and lower teeth of a patient, and at least one suction inlet configured to suction fluid out of the oral cavity; an irrigation element with a second plate for placement between the upper and lower teeth of the second side of the oral cavity and one or more irrigation outlets configured to irrigate the oral cavity with fluid; a suction port that is fluidically coupled to the suction element for providing suctioning of the oral cavity during use; and an irrigation port that is fluidically coupled to the irrigation element for providing irrigation to the oral cavity during use.

An oral insert includes a plurality of fluid nozzles, a plurality of manifolds, and an attachment mechanism configured to be releasably attach with a handle. Each of the manifolds is associated with a corresponding subset of the plurality of fluid nozzles. The attachment mechanism includes a manifold connector having a plurality of manifold openings arranged in a circle. Each of the plurality of manifold openings is associated with one of plurality of manifolds.

An oral care system includes a fluid reservoir, a check intake valve, and a pump configured to cause fluid to be provided from fluid reservoir to an oral insert of the oral care system via the check intake valve. The fluid reservoir includes one or more fluid flow disrupters. The check intake valve is located at an offset from a center of the fluid reservoir.

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.

A manifold of a plurality of manifolds associated with an oral insert is selected. The manifold includes a set of nozzles. Each of the plurality of manifolds is associated with a same expected performance within a threshold tolerance. A performance of the manifold is tested in part by generating a pressure-flow curve for the manifold based on corresponding measurements performed at a plurality of different flow rates and determining that the manifold is defective in response to the generated pressure-flow curve for the manifold not being bounded by an upper limit curve and a lower limit curve. In response to determining that the generated pressure-flow curve for the manifold not being bounded by the upper limit curve and the lower limit curve, forgoing testing of one or more remaining manifolds associated with the oral insert is forgone and the oral insert is determined to be defected.

Disclosed are devices, systems and methods for treating periodontal disease and/or other oral wounds using particularized oral appliances and associated negative pressure systems. The various oral appliances include one or a plurality of surfaces for engagement with various anatomical structures within the oral cavity, where the engagement can include sealing engagement with soft tissue (gingival) surfaces of the upper and/or lower dental arches. Additional features disclosed can further promote healing of regions affected by periodontal pocket formation.

An oral care system that provides a beneficial effect to an oral cavity of a mammal by using a liquid effective for providing the beneficial effect, where the system includes means for directing the liquid onto a plurality of surfaces of the oral cavity, means for providing the liquid to the means for directing the liquid onto the surfaces of the oral cavity, means for providing reciprocation of the liquid over the plurality of surfaces under conditions effective to provide the beneficial effect; and a reservoir for containing the liquid.

Hands-free systems, devices and methods, adapted for brushing, cleaning and treating all of a user's teeth simultaneously, are provided. In some embodiments, such a device comprises brushes for cleaning all of a user's teeth simultaneously. In some embodiments, such a device includes a generally U-shaped channel(s), accepting, cleaning and/or treating all of a user's teeth simultaneously. Customized fluid jets within such devices are provided, introducing dentifrices and other treatments into the channels. In some embodiments, compartments and cartridges with a proprietary form factor for delivering dentifrice and other treatments and for disposing of waste without mess are provided. In some embodiments, data are gathered, analyzed and serve as the basis for a treatment plan, which may then be carried out by the system(s), device(s) and method(s), over time.
