According to an exemplary embodiment, a foolproof periodontal sulcus brush and intrasulcular medicament applicator, having one or two heads, for use in a variety of humans and animals, and its method of use, may be shown and described. The foolproof periodontal sulcus brush and intrasulcular medicament applicator can have offset heads and bristle areas, and include multiple curves of a neck portion—to provide improved access and cleaning ability, and may be separable or combined with toothbrush and/or other oral care brush elements or components, including a motorized or manual handle.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

An oral irrigator has a base unit housing a motor and a pump, a removable reservoir defining a reservoir cavity configured to mechanically couple to a top surface of the base unit and fluidly couple the reservoir cavity to the pump, and a belt drive assembly connecting the motor to the pump. The belt drive assembly includes a drive pulley connected to an output shaft of the motor, a driven pulley spaced apart from the drive pulley and mechanically connected to a piston that drives the pump, and a continuous belt connecting the drive pulley to the driven pulley. A handle for the oral irrigator may include a housing defining a slot formed in an outer wall of the housing.

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.

An oral care appliance and a method of controlling pressure in the oral care appliance are disclosed. The pressure inside a mouthpiece of the oral care appliance is controlled by an actuator. The actuator is triggered when a targeted threshold value of an operational characteristic is reached. Automatic control of the pressure in the mouthpiece enhances both cleaning efficiency and user comfort.

A toothbrush comprising at least a grip part comprising a signal generation part which outputs a drive signal supplied to an oscillator, a protrusion part which is disposed on an end part of the grip part, an oscillation part in which the oscillator is positioned on the leading end of the protrusion part, and a brush which is positioned in a position facing the oscillation part, said toothbrush being characterized by the frequency of the drive signal being between 3-5 MHz inclusive.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

An oral care implement handle or a refill head therefor. The refill head may include a sleeve portion extending from a proximal end to a distal end, the sleeve portion having an inner surface that defines an internal cavity. The internal cavity may extend along a sleeve axis from an open bottom end at the proximal end of the sleeve portion to a closed top end, the internal cavity being configured to receive an attachment portion of a stem of an oral care implement handle. The internal cavity may have a proximal section adjacent the open bottom end and a distal section adjacent the closed top end. The distal section of the internal cavity may include a central portion located on the sleeve axis and at least one slot portion radially extending from the central portion.

A plurality of mass-produced versatile toothbrush refills for a secure removable engagement with a plurality of mass-produced non-identical toothbrush handles including handles of electric toothbrushes and handles of manual toothbrushes. Each of the refills comprises: a proximal and distal ends opposite thereto and a longitudinal axis extending between the proximal end and the distal end; a cleaning head with a plurality of cleaning elements adjacent to the distal end; and a neck extending from the cleaning head and terminating at the proximal end. The neck has a wall defining a cavity for receiving a handle engagement structure of any one of the toothbrush handles. The refill includes a refill engagement structure configured to form the secure removable engagement with the handle engagement structure.

The present disclosure provides a brushhead for an power toothbrush detachably attached to a handle of the power toothbrush, the handle including a vibrating drive shaft, the brushhead comprising: a main body defining a receiving cavity which is configured to receive at least a portion of the vibrating driving shaft, the main body including a cavity wall substantially surrounding the receiving cavity and an end connected to the handle, with an opening which is defined in the end of the main body in air communication with the receiving cavity, so that the vibrating driving shaft is capable of being inserted into the receiving cavity through the opening; and an engaging assembly mounted in a side wall of the main body, the engaging assembly comprising an elastic member, which is made by metal material; wherein, a recess is defined in the outer surface of the side wall, the elastic member is deformably received in the recess, the elastic member is elastically deformed by force provided from the vibrating drive shaft when the brushhead is attached to the handle of the power toothbrush.
