A chassis of an oral cleansing device is provided. The oral cleansing device may include a first chassis half including a first threaded portion, a second chassis half including a second threaded portion, and a nut threaded onto the first threaded portion and the second threaded portion to at least partially secure the first chassis half to the second chassis half. The threaded portions may be defined on respective ends of the first chassis half and the second chassis half. The nut may engage chamfered edges of the first chassis half and the second chassis half. Engagement of the nut with the first chamfered edge and the second chamfered edge may produce a radial compressive force on the chassis halves. The first chassis half and the second chassis half may at least partially define a chassis that is positioned within a handle of the oral cleansing device.

A toothbrush for use by an operator and capable of being connected to a suction device and a syringe. The toothbrush includes a head, a handle, and a suction assembly. The head includes a plurality of bristles and an irrigation port configured to be in fluid communication with the syringe. The handle is coupled to the head and includes a user interface and a controller configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to feedback from the operator through the user interface. The suction assembly is coupled to one of the head and the handle and configured to be coupled to the suction device. The suction assembly includes a suction tip that is movable relative to the head.

An oral cleansing device (e.g., an irrigating, electric toothbrush) is disclosed. The oral cleansing device includes a handle, a cleansing attachment (e.g., a brush head attachment), and an irrigating attachment (e.g., an oral irrigator tip). The handle includes one or more control buttons to activate motion of an output shaft and/or an irrigating feature of the oral cleansing device. The cleansing attachment includes a plurality of bristles and is attachable to the handle such that movement of the output shaft is transferred to the cleansing attachment. The irrigating attachment defines an internal fluid passageway for receiving fluid from the handle and is attachable to the handle such that movement of the output shaft is not transferred to the irrigating attachment.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system. A motorised drive unit drives movement of a bristle carrier relative to the handle. At least part of an inlet conduit of the fluid delivery system lies adjacent to the external surface of the motor, and at least part of an outlet conduit of the fluid delivery system extends through the motor.
