Abstract
The present invention relates to an enhanced cleaning toothbrush bristle pattern, wherein two rows of taller bristle tufts transversely divide the toothbrush head into three sections, the bristle tufts within each section having a trim pattern which in profile is convex in relation to the toothbrush face; wherein the two rows of taller bristle tufts penetrate between teeth, while the curved trim profile of each section provides for good conformity to the curved tooth surfaces and for an improved sweeping action.
