The water flow impacts the whitening pills so that the whitening pills are dispersed in the water and mixed to form a whitening solution. In order to prevent the whitening pills from mixing with water to form a whitening solution, the dispersed whitening pills form larger whitening pill particles that enter the user's mouth. By providing a water inlet connected to the water flosser body on the side of the connecting section 22 away from the water spraying section 23, a filter 21 for filtering the whitening solution is connected to the inner wall of the water inlet, thereby replacing the existing arrangement of the filter 21 inside the connecting section 22, thereby intercepting larger whitening pill particles outside the connecting section 22 of the nozzle 20, thereby preventing larger whitening pill particles from being retained in the connecting section 22 and causing the connecting section 22 to be contaminated, thereby preventing larger whitening pill particles from entering the user's mouth. The whitening solution in the water flosser body enters the nozzle 20 through the water inlet, so the filter 21 can intercept larger whitening pill particles in the water flosser body.
