The toothbrush includes a handle portion, a neck portion, and a head portion, and the head portion includes a first head portion and second head portion. The second head portion is detachable from the first head portion. The toothbrush further includes a button portion and an attachment/release mechanism. The button portion is actuatable to actuate the attachment/release mechanism to facilitate detachment of the second head portion from the first head portion.

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.

A head for an oral-care implement comprises a number of colored filaments extending from a mounting surface of the head and being grouped together to define an initial color pattern. The colored filaments comprise at least a first and a second type of filament, wherein the types of filaments differ in color-changing characteristics over a pre-defined period of time, the pre-defined period of time being the same for the first and the second type of filament so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern, the first color pattern being different form the initial color pattern.
