The pulsating jet water flow of about 30 times per second, cleans dirt and debris that are hard to fall off with a toothbrush. Since it is water, it can reach the smallest gaps, and it will not hurt your gums. The brush nozzle vibrates with a pulsating jet water flow, eliminating the cause of periodontal disease and bad breath odor.
