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 lever5having a brush4is swingingly supported in the nozzle1, a flow passage3leading to a blow-out port1aat an end of a nozzle1is partly bent, and a resilient member7is provided at the bent portion to urge the brush lever5in a direction opposite to the direction of flow of water, so that the brush lever5oscillates reciprocally due to the resilient force produced by the resilient member7and the pressure of water flow, causing the bristle tips of the brush4to oscillate in a direction at right angles with the direction of length of the bristles outside the nozzle1.
