Abstract

The present invention relates to a toothbrush. The invention relates in particular to a toothbrush filament having a filament body surrounding a matrix material in which grains are embedded, wherein the matrix material and the grains have a different resistance to etching so that by etching the matrix material and/or the grains a surface structure can be created on the filament body at least in the area of the tapering end section. According to one aspect of the present invention, grains having a shell structure with a grain shell, in which is encapsulated a grain core comprising a core material different from the shell material, have been embedded in the matrix material of the filament.
