Present invention teaches a portable teeth-cleaning device where a flexible water tank is stored inside the main body of the device; when water is being sent into the flexible water tank, getting it ready for use, the tank will expand in volume and come out of the main body. A pump is used to perform the water intake function and the water squirt-out function, via guide channels, with controlling means to control the mechanism of either 3 valves or 2 switch valves to effectuate the intended functions.

An oral irrigator including a base and a handle. The base includes a fluid reservoir, a pump in fluid communication with the fluid reservoir, and a base wireless communication component in electrical communication with the pump. The handle is in fluid communication with the pump. The handle includes a handle wireless communication component and one or more control buttons in communication with the handle wireless communication component. The handle wireless communication component transmits control signals from the one or more control buttons to the base wireless communication component to adjust an operating parameter of the pump.

A mixing system adapted for installation within an oral care appliance and a method of preparing an oral care composition to be delivered to a mouthpiece of the oral care appliance are disclosed. Some of the disclosed systems and methods allow for the generation of an on-demand oral care composition for use in dental cleaning.

The present invention provides new dental care products comprising self-assembling peptides (SAP) that are capable of undergoing self-assembly at a certain pH for use in dental care, e.g. preventing and/or treating a tooth lesion such as a caries lesion, remineralising a tooth surface, increasing smoothness or shine or increasing hardness of a tooth surface. The dental care products may be administered following a simple protocol involving multiple steps, e.g., comprising tooth brushing with a sonic tooth-brush such as an ultrasonic toothbrush and/or use of an oral irrigator, thereby enabling non-targeted treatment of a plurality of teeth in a subject, independent of the diagnosis of active caries, i,e., not previously successfully treated caries. The invention also relates to said method as well as kits and devices suitable therefor.

A dental water jet is provided. The dental water jet may include a base unit, a reservoir supported by the base unit, a handle supported by the base unit, and a container covering an opening of the reservoir. The container may include a base supported by the reservoir and a lid movable relative to the base. The container may be configured to store one or more tips for use with the handle.

An oral cleaning device according to the disclosure includes a body unit including a pump configured to discharge washing liquid, a tube connected to the body unit to allow the discharged washing liquid to flow through the tube, a washing unit connected to the tube to discharge the washing liquid, a first operation part provided at the washing unit, a controller configured to control the pump in accordance with operation of the first operation part, and a communication unit configured to establish a communication connection between the first operation part and the controller.

A docking and charging station (100) for use in conjunction with a hand-held fluid droplet appliance (10) for dental cleaning, the docking and charging station (100) comprising a charging base (102) for recharging the hand-held fluid droplet appliance, a reservoir (110) for holding a larger amount of liquid (112) than can be held in a chamber of the hand-held fluid droplet appliance, and a docking refilling alignment mechanism for properly aligning and securing the hand-held fluid droplet appliance in the cradle (160) of the docking and charging station when the hand-held fluid droplet appliance is mounted into the docking and charging station to prevent spillage, leaking or non-refilling of the appliance from the reservoir if there is not proper alignment.

A toothbrush or oral cleaning implement including a handle defining a first fluid conduit and a handle inlet port, a brush tip extending from a first end of the handle and defining a second fluid conduit, the second fluid conduit in fluid communication with the first fluid conduit, a brush head supported on an end of the brush tip including a fluid outlet in fluid communication with the second fluid conduit, a handle valve positioned between the handle inlet port and the first fluid conduit, and a base removably connected to the second end of the handle. The base including a base fluid inlet port that connects with an external fluid source, a base fluid outlet port in fluid communication with the base fluid inlet port, and a base valve that selectively opens and closes the base fluid outlet port.

A toothbrush including a chassis assembly, an output shaft configured to connect to a brush head and extending at least in part through a portion of the chassis assembly, a power train assembly operably connect to the output shaft, where the power train assembly oscillates the output shaft. The toothbrush also includes a fluid connector operably coupled to the chassis assembly and fluidly coupled to the output shaft via the power train assembly. The fluid connector rotates 360 degrees relative to the chassis assembly.
