摘要： An oral care refill head and an oral care kit comprising the same. The oral care refill head may include a sleeve portion, a head portion, and an elastomeric prophy cup. The sleeve portion may have an inner surface that defines an internal cavity for receiving a portion of a stem of an oral care implement handle therein so that the oral care refill head can be repetitively attached to and detached from the oral care implement handle. The elastomeric prophy cup may comprise an outer surface that forms at least a portion of a peripheral side surface of the head portion. The elastomeric prophy cup may be formed by injection molding an elastomeric material onto a support portion of the head portion. The oral care refill head may be packaged together with a store of an anti-sensitivity oral care material to form a kit.

摘要： An electrified toothbrushing device for reducing gingival recession includes an electric toothbrush, which in turn comprises an elongate housing in which a motor and a battery are attached and positioned. A drive shaft of the motor extends through a first end of the elongate housing. A brush head is selectively attachable to the first end of the elongate housing so that the brush head is operationally engaged to the drive shaft. A plurality of bristles of the brush head is rotatable about an axis that is defined by the drive shaft. The battery is operationally engaged to the motor so that the battery is positioned to selectively power the motor. The elongate housing can be grasped in a hand of a user to selectively position the plurality of bristles along sets of upper and bottom teeth to clean the teeth.

摘要： The invention relates to method of manufacturing a recess wall lined with bristles for a mouthpiece for simultaneously brushing at a plurality of dental positions, and to a recess wall and mouthpiece manufactured according to the method. In a providing step, an elongate, continuous, bristled sheet part having a first side lined with a plurality of bristles is provided. The elongate sheet part defines a length axis extending parallel to the sheet part and, viewed transverse to the length axis, a cross-sectional shape. The sheet part obtained in the providing step has an initial condition in which the cross-sectional shape has an initial shape, and the length axis is arch-shaped. In a transforming step, the sheet part of the providing step is transformed from the initial condition to a final condition to provide the recess wall. In the final condition the cross-sectional shape has a final U-shape, the length axis is arch shaped, and the first side is a concave inner side of the final U-shape. The first side is in the final condition more concave than in the initial condition.

摘要： A handle for an oral-care implement for safe and hygienic use by multiple users includes an electrical motor and a detachable head. The handle has a display for displaying instructions to control functional operation of the handle, a microcontroller for controlling the motor and the display, and at least one switch to allow a user to control the functional operation of the handle, including causing the output element to vibrate in at least one oral-hygiene mode having an oral-hygiene frequency and causing the output element to vibrate in a disinfection mode when the handle is being disinfected before or after being used for the oral-hygiene routine. The disinfection mode has a modulated frequency, different from the oral-hygiene frequency, and alternating up and down between a low modulated frequency and a high modulated frequency, wherein the high modulated frequency is at least 50 percent greater than the low modulated frequency.

摘要： A teeth cleaning system, which provides improved coverage or brushing area. The system includes an actuated tray comprises brushing elements. The brushing elements may be positioned to engage the front, rear, and top surfaces of the upper and lower jaw teeth. The actuation may be configured to oscillate the tray in a lateral direction which may brush all the surfaces of teeth simultaneously. Some embodiments include a higher density of bristles which increases the effectiveness of brushing. In addition, aspects of the system reduce the time spent brushing teeth.
