Abstract

The invention is directed to a brush for cleaning the teeth, the brush being suitable for use in a toothbrush having a handle member and a brush member and comprising a bristle supporting structure and bristles fixedly secured thereto. The bristle supporting structure is configured as a rod-shaped stem having a first and a second end portion and carrying no bristles in the region of the second end portion. The bristles extend radially relative to the stem in the region of the first end portion and are arranged in a circumferentially distributed pattern. The length of the bristles decreases starting from the first end portion of the stem in the direction of the second end portion of the stem. This brush allows effective and gentle cleaning of the teeth, in particular the interproximal spaces thereof.
