Abstract:
A toothbrush includes a head having a prophylaxis polishing cup closely surrounded by cleaning elements in the form of a bristle ring extending above the upper surface of the cup. Alternatively, the cups could be in the form of arrays of densely packed cleaning elements. The area formed by these configurations retains toothpaste on the toothbrush during use. Additional cleaning elements may be arranged about the periphery of the toothbrush head. The toothbrush may be a powered toothbrush wherein the cups and/or bristle rings rotate, oscillate or reciprocate to better clean teeth.
