Abstract of the Disclosure:- A toothbrush comprising at least two adjacent rows of filaments of which in one row the filaments are upright and in the other the filaments are inclined. During longitudinal brushing the inclined filaments become more effective by flexing to the upright, and during lateral brushing the inclined filaments support the adjacent upright filaments against undue flexure.
