Abstract
A toothbrush construction is described in which a bristle head is made moveable with respect to a handle and contains adjustable springs to permit presetting of the brushing pressure. The springs are so formed as to have a break away feature. The user is thus made aware whenever he exerts more than the preset pressure and can learn to brush at a pressure which permits good cleansing and minimizes brushing damage to his teeth and gingival tissue.
