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, the bristles or bristle tufts having different lengths. The contour of the bristles may be selected to allow substantially all of the bristles to contact the dentition during brushing.
