Using a regular toothbrush is not enough to remove 100% of plaque. Oral B has therefore developed a special mouthwash that cleans the space between the teeth and other places that the toothbrush cannot reach. The Oral B Oxyjet MD 20 mouthwash uses a gentle water flow with microbubble technology for thorough plaque removal. Using the shower regularly effectively prevents bleeding gums and significantly reduces the number of bacteria in your mouth.
