A back-flushing plate (4) of a multifunctional oral care tool is provided at a back end of brush heads (1) and has an end portion lower than an end portion of the brush heads (1). A pair of brush heads (1) is driven to rotate by a pair of transmission rods (5), such that the brush heads produce a powerful suction flow. Sucked water splashes onto the back-flushing plate and generate a powerful flush flow, thereby attains a goal of flushing the oral waste away. It solves a problem of deep cleaning of furs and also solves a problem of waste liquid, such as tooth-brushing foam, remaining in an oral cavity.

A splatter guard for a dental cleaning tool eliminates the splatter by gathering splatter first on the outer lower one-third to one-half of the fructoconical prophy cup using combination of vanes and the dimples. As the splatter migrates upwards, the splatter guard wipes off the splatter. The reason the splatter guard is constructed smaller than the cup is because it allows the cup to flex outward without interfering during use thereof. The splatter guard can be attached several different ways, including slide in, snap on, secured between two half-housing members, or formed integrally with the housing, for example. The drive train is housed in a partial split contra angle housing which allows accurate positioning of the gears as it is required to ensure that the cup rotates concentrically and remains in touch with the knife edge of the splatter guard.

A device for brushing teeth having multiple brushes that provide rotary and/or oscillating motion. The device has a right lateral brush, a left lateral brush, and an upper brush. Each of the three brushes is connected to, and driven by, a respective supporting rod. Each of the supporting rods is driven by a respective gear. The device includes a motor or engine for generating rotational movement which is transferred to each of the gears by a transmission. The transmission is configured to simultaneously provide both rotary and lateral movement to the brushes, thereby creating an oscillating motion.

A dental implant cleaning or chemotherapeutic treatment device includes an elongated hollow stem, and bristles operably attached to the elongated hollow stem adjacent a first end of the elongated hollow stem and projecting from the elongated hollow stem nonparallel to the elongated hollow stem.

Embodiments of the present invention comprise a powered toothbrush comprising a bristle head, an outer gear, and a plurality of bristles. Both the bristle head and the outer gear may comprise a distal end, a proximal end, and a center. The distal end of the bristle head may mate with the proximal end of the outer gear. The outer gear may rotate about a first axis of rotation. The mating between the bristle head and the outer gear may cause the bristle head to orbit the first axis of rotation via one or more bristle paths while simultaneously completing one or more rotary movements about a second axis of rotation, which may move along the bristle paths with the bristle head.

A prophylaxis angle that is configured to be attached to and operated by a powered dental handpiece. The prophylaxis angle includes a cup having a first end and a second end. The first end is couplable to the dental handpiece and at least one projection is at the second end of the cup.

An interdental cleaning member includes a brush having a plurality of bristles, each of the plurality of bristles comprising a bristle shaft, the bristle shaft extending from a shaft base to a shaft tip, and formed to have a thickness and resiliency configured to clean interdental areas and areas interposing a tooth and gum tissue surrounding the tooth.

A pre-charged prophy angle having a (a) housing that includes a paste chamber, a rotatable head, a drive shaft, and a tube defining in part the paste chamber, the housing and paste chamber configured such that paste within the paste chamber can be dispensed without contacting the drive shaft; (b) a cup secured to the rotatable head, and (c) a paste dispensing assembly having a plunger movably secured to a push rod configured to reciprocally move linearly within the housing, the plunger including a clip for gripping the push rod such that linear movement of the push rod in a first direction causes the plunger to move in the first direction, while the clip precludes movement of the plunger in a second direction when the push rod in directed in the second direction.
