Abstract
The brushhead includes a brushhead member which includes a bristle field, the brushhead member being adapted for cleaning teeth as part of a power toothbrush, wherein the brushhead in operation moves in a reciprocating action. In one embodiment the brushhead includes a rim member which extends around at least a substantial portion of the brushhead, the rim member extending around the entire bristle field and having an upper edge which is lower than the top of the bristles. The rim member has a different flexibility than the bristles so that the movement of the rim member and the bristles is out of phase during operation of the toothbrush, which results in fluid from the bristles being directed toward the teeth during operation of the toothbrush.
