Abstract: According to one aspect, an electric toothbrush may include a handle defining a volume, a motor disposed in the volume defined by the handle, a shaft having a first end portion and a second end portion, the first end portion coupled to the motor in the volume, the second end portion extending from the volume of the handle and fluidically isolated from the volume of the handle and, with the second end portion fluidically isolated from the volume of the handle, the second end portion releasably engageable in mechanical communication with a cartridge including at least one dental cleaning element, and a sleeve conforming to an outer surface of the handle and circumscribing at least a portion of the shaft fluidically isolated from the volume of the handle.

Abstract: Devices, systems, and methods of the present disclosure are generally directed to facilitating user control of high-pressure flow of liquid for oral irrigation carried out as part of personal dental care. Such control over high-pressure flow may reduce the likelihood of errant spray of liquid outside of the user's mouth (e.g., onto mirrors, countertop surfaces, or the user's clothes). Such improved control over errant spraying may reduce the potential for frustration and, thus, may promote maintaining oral irrigation as part of a personal dental care routine. Further, or instead, through facilitating user control of high-pressure flow of liquid, the devices, systems, and methods of the present disclosure may improve the effectiveness and efficiency of self-administered oral irrigation in promoting a user's oral hygiene.
