A head for an oral care implement comprises a mounting surface and at least one tuft extending from the mounting surface. The tuft comprises a first group of filaments and at least a second group of filaments. The first group of filaments is surrounded by the second group of filaments. The filaments of the first group have a first length and the filaments of the second group have a second length, the first length being different from the second length. The difference in length between the first length and the second length is about 1.1 mm to about 1.9 mm.

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, a dental care device is customized for a particular user, including: (1) a support plate having: (a) a first portion configured to be inserted into a mouth; and (b) an attachment mechanism configured to attach the dental care device to a drive assembly; and (2) an elastomer (elastic polymer) portion enclosing the first portion of the plate, the elastomer portion including a plurality of cleaning tips and shaped in accordance with dental details of the particular user.

A personal care product dispensing system with a body defining a cavity configured to retain a spreadable personal care product. A spreadable material is positioned within the cavity. A cover is mounted to the body. The cover defines a first aperture extending from a top surface of the cover to a bottom surface of the cover. A flexible applicator pad is mounted to the top surface of the cover with a valve positioned over the first aperture. The flexible applicator pad has a plurality of projections and a projection density of 10 to 40 projections per square centimeter.

A cleaning brush includes a rigid bottom base wall portion, side wall portions extending from opposite sides of the bottom base wall portion, a first rigid top wall portion extending from an upper end of one side wall portion, and a second rigid top wall portion extending from an upper end of the other side wall portion. A slot is provided between facing ends of the top wall portions which extends between first and second ends of the cleaning brush. A first set of first bristles extends from the bottom base wall portion, and second and third sets of bristles extend from the top wall portions. Free ends of the bristles may touch each other, be spaced from each other, or may extend past each other.

A dental appliance and method employing an arcuate mouthpiece with a plurality of substantially H-shaped plate segments having opposing side walls joined by transverse bridge portions splitting the opposing side walls into upper and inverted channels dimensioned for receiving the teeth in the maxillary dental arch and mandibular arches respectively so that one or more cleaning modules, such as tufted bristles, may be activated to simultaneously clean a working surface of the teeth of the maxillary dental arch and the teeth of the mandibular dental arch adjacent to the plate segments.

A dental cleaning system comprises a first wall element for mounting against the inner, lingual, tooth surfaces of one or both jaws and a second wall element for mounting against the outer, facial, tooth surfaces of said one or both jaws. A drive mechanism couples the first and second wall elements, and imparts a drive vibration of the first and second wall elements towards each other and apart from each other.

The present disclosure describes a scrubber system for removing material from, or smoothing the surface of, an object. According to an example embodiment, the scrubber system comprises one or more scrubbing disks, spacer disks, and retaining collars configured for interlocking with other cooperatively configured scrubbing disks and spacer disks. The scrubbing and spacer disks are arrangeable end-to-end along a shaft extending therethrough and between opposed retaining collars to form a scrubber custom-configured for a particular application. The scrubbing disks may include one or more types arranged, with or without any spacer disks, in any desired configuration. When the scrubbing disks and/or spacer disks are positioned adjacent one another end-to-end, lateral and end mating surfaces at the adjacent ends of the respective scrubbing and/or spacer disks abut one another, limiting relative rotation therebetween and substantially forming a single, contiguous outer surface that prevents removed material from becoming lodged therebetween.
