A dental cleaning device includes a bite plate to clamp an upper and a lower arch in a predetermined bite position; a track fixed to the bite plate to provide a dental arch movement; and a carrier holding dental instruments thereon and moving along the track.

An omnidirectional scientific toothbrush includes a brush handle and a brush head having a U-shaped structure. A central gearset, and tooth outer side brush rollers and tooth inner side brush rollers, both of which are respectively arranged in an upper row and a lower row according to tooth layout, and a tooth end surface brush roller driven by the central gearset are installed in an inner cavity of the brush head. The tooth end surface brush roller is located in a space defined by the tooth outer side brush rollers and the tooth inner side brush rollers. The rotating action of the tooth end surface brush roller allows the tooth end surface brush roller to simultaneously brush occlusal surfaces of Upper and lower rows of teeth. Thus the cleaning operation of all of the teeth in the mouth may just be finished at one time automatically.

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.

A mouthpiece-type teeth cleaner, comprising: an excitation source, configured to generate one or more groups of alternating excitation signals; and a cleaning system, configured to generate one or more cleaning operations according to the excitation signals, with different cleaning actions applied to various parts of the teeth; wherein the teeth cleaner has a correlation between the cleaning operation and the cleaning action and each part of the tooth, and the correlation enables each part of the tooth to be individually cleaned.

Fluid is provided to a manifold selected among a plurality of manifolds associated with an oral insert. Each of the plurality of manifolds is associated with a same expected performance within a threshold tolerance. An actual performance of the manifold is determined based on a pressure and a flow rate associated with providing the fluid to the manifold. A performance of the oral insert is verified based on whether the actual performance of the manifold matches the same expected performance within a threshold tolerance.

Animal dental hygienic device, comprising: A hollow body having an exterior surface and an interior cavity, and being sized to fit within the mouth of the animal and to be bitten thereby. The hollow body having a plurality of apertures positioned along its exterior surface, the apertures extending from the exterior surface to the interior cavity. Each aperture having dental-hygienically active dimensions allowing an animal's tooth to penetrate through the aperture; such that (i) material surrounding the aperture frictionally engages the animal's tooth's outer surface during penetration of the aperture by the tooth, the material surrounding the aperture being of sufficient hardness to scrape the tooth's outer surface during frictional engagement to remove dental plaque, and (ii) a portion of the animal's tooth extends within the interior cavity during penetration of the aperture by the tooth.

The invention discloses a tooth cleaner mainly composed of a brace and a handle, the brace comprises an upper tooth socket and a lower tooth socket, a plurality of small open holes which are arranged at intervals are distributed in the upper tooth socket and the lower tooth socket, one end of each of the small open holes is connected with a first guide pipe embedded into the brace, the other ends of the first guide pipes extend into the handle and are connected with a pump outlet of a pump module arranged inside the handle, the pump module also comprises a pump air inlet and a pump water inlet, the pump water inlet of the pump module is connected with a water storage module in the handle by a guide pipe, and the pump air inlet of the pump module communicates with an air inlet in the surface of the handle by a guide pipe. By using the tooth cleaner, the problems of poor cleaning and atomizing effects and poor user experience of the original tooth cleaner are solved.

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 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.
