Abstract
A head for an electric toothbrush includes a support member having a plurality of holes extending completely therethrough. A plurality of tufts of bristles each extends through one of the holes. A first brushing end of each tuft projects from a first side of the support member. Each tuft is prevented from being withdrawn from its hole when a tensile force is applied to the first end of each tuft along a long axis of the tuft. A resilient cushion is positioned adjacent a second side of the support member such that a second end of each tuft can contact the cushion. When a compressive force is applied to the first end of each tuft along the long axis of each tuft, each tuft can move in its hole in a first direction into the cushion. When the compressive force is removed the cushion causes each tuft to move in its hole in a second direction substantially opposite the first direction.
