Provided is a brush head for an oral cleaning device for cleaning teeth with a combination of brushing and emitting of a cleaning agent. The brush head comprises a bristle set for brushing the teeth and a nozzle for emitting the cleaning agent. When actuating the bristle set from a first configuration, which is optimized for brushing, to a second configuration, which is optimized for emitting of a cleaning agent, at least a part of the bristle 5 set is moved away from the nozzle and/or away from a path of the cleaning agent when being emitted from an orifice of the nozzle.

A cell of a brush making device for making at least a part of a toothbrush, having a pin unit having at least one pin, a pin holding sub-unit and a pin guiding sub-unit, the pin having a first section having a first end and a second section having a second end, the first section having a holding structure, and at least one spring section arranged between the first section and the second section, the pin holding sub-unit having a holding structure that is engaged with the holding structure of the pin for fixedly holding the pin, the pin holding sub-unit and the pin guiding sub-unit being arranged for being movable along a first direction towards and away from each other, and the pin guiding sub-unit having a channel for guiding at least a portion of the second section of the pin, the channel being inclined against the first direction.

A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. At least two types of filament have staggered time-controlled color changing properties, wherein each of said type of filament changes its color within pre-defined time periods, the pre-defined time periods being different from each other so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern and over a subsequent second pre-defined period of time to a second color pattern, the second pattern being different from the first pattern.

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.

A method for producing a mouthpiece toothbrush is provided, in which at least one dental arch of the patient for whom the toothbrush is intended is scanned to generate scan data, or an impression of the dental arch is made. Based on the scan data or the then digitised impression, the dental arch space occupied by the dental arch is recorded. A bristle space is constructed around the at least one dental arch, and a toothbrush moulded piece is calculated, the surface of which facing the dental arch is determined by the dental arch space plus the bristle space. The surface is covered with a bristle carpet.

A head for an oral-care implement, having an elongated mounting surface with an outer circumference, includes two outer rows of tufts extending from the mounting surface along the longitudinal axis in proximity to the outer circumference, and two inner rows of tufts extending from the mounting surface and arranged between and parallel to the outer rows. The tufts of the outer rows have a longitudinal extension and an elongated cross-sectional area perpendicular thereto. The elongated cross-sectional area has a longer axis and a shorter axis, wherein the longer axis defines an angle α of about 20-65 degrees relative to the longitudinal axis. The tufts of the outer rows are inclined relative to the mounting surface by an inclination angle (β) of about 65-80 degrees. The tufts of the inner rows are inclined relative to the mounting surface by an inclination angle (γ) of about 60-85 degrees.
