A toothbrush in the form of a manual toothbrush having a rectangular bristle array (1) or in the form of an electric toothbrush having a round bristle array (1), formed from individual bristle bundles (2), arranged adjacent to each other on a brush head and standing erect at approximately right angles thereto is provided. At least some of the individual bristle bundles (4) are at least partly inclined or roof-shaped with respect to a plane approximately parallel to the brush head (2), such that bristles in the bristle bundles (4) stand to differing heights whereby the terminal surfaces arranged at the applied ends of the bristle bundles (4) are embodied as inclined surfaces (5) or as partly inclined surfaces. The bristle bundles (4) are arranged in a line adjacent to each other along imaginary straight or curved connecting lines, or for round brushes, along segmental or circular connection lines. At least individual, and preferably large groups or all of the bristle bundles (4) in the bristle array (1) are arranged with the inclined surfaces (5) thereof rotated to varying degrees relative to each other and to the connecting line(s), such that a number of differently oriented inclined surfaces are provided for cleaning teeth so that a particular inclined surface is in a favorable orientation to engage in an interdental space between teeth for thorough cleaning
Toothbrush comprising an elongated, rectangular, and/or round bristle array (1), which is formed from individual bristle bundles (4) or bristle tufts arranged next to each other on a brush body (2) and extending away from the body, at least some of the bristle bundles (4) on a use end facing away from the brush body (2) are at least partially beveled and/or formed with a roof shape relative to a plane extending approximately parallel to the brush body (2), such that bristles of the at least some of the bristle bundles (4) extend at different lengths, so that terminal surfaces arranged at the use ends of the at least some of the bristle bundles (4) are formed as inclined surfaces (5) or as partially diagonal surfaces, wherein the at least some of the bristle bundles (4) are arranged adjacent to each other along imaginary straight or arc-shaped connecting lines, or for round brushes circular-arc or circular connecting lines on the brush body, wherein the at least some of the bristle bundles (4) of the bristle array (1) are arranged with the inclined surfaces (5) rotated relative to each other and relative to the connecting lines by different angles, which are different from 90° and 180°.
Toothbrush according to, wherein in the bristle array (1), the bristle bundles (4) provided with the inclined surfaces (5) or diagonal surfaces and bristle bundles (4a) with approximately horizontal, rounded, and/or pointed use surfaces are combined with each other and such differently shaped ones of the bristle bundles (4a) within the bristle array (1) are directly adjacent to each other and/or are arranged as groups, within said groups equivalent or similar bristle bundles (4a) are combined, wherein within at least one group of the bristle bundles (4) with inclined surfaces (5) are arranged, which are arranged opposite each other or rotated relative to their imaginary connecting lines by angles that are different from 90° or 180°.
