摘要：
Toothbrush heads, e.g., for power toothbrushes, are provided. The toothbrush heads include a support member and a plurality of bristles or tufts of bristles extending from the support member, at least some of the bristles or bristle tufts having different heights, the bristles arranged so that their heights are symmetric, in a non-translatable mirror image symmetry, about two planes of symmetry.
