Abstract
A safe brushing is realized without sticking the gum if the bristle tips are once inserted in a pocket of a tooth by using a system having a brush of which the bristle tips automatically vibrate in a direction at right angles with the direction of length of the bristles. A brush leverhaving a brushis swingingly supported in the nozzle, a flow passageleading to a blow-out portat an end of a nozzleis partly bent, and a resilient memberis provided at the bent portion to urge the brush leverin a direction opposite to the direction of flow of water, so that the brush leveroscillates reciprocally due to the resilient force produced by the resilient memberand the pressure of water flow, causing the bristle tips of the brushto oscillate in a direction at right angles with the direction of length of the bristles outside the nozzle
