The EW1311 oral irrigator in the trendy mint green color removes food particles from between teeth and flushes away floating plaque from gum pockets. With three adjustable water pressure settings, this oral irrigator promotes blood circulation in the gums through gentle massage pressure. You can choose between a powerful or gentle water stream according to your preference. The water stream eliminates bacteria that cause periodontal disease from the gum pockets. It gently stimulates the gums with approximately 1,400 pulses per minute in Air in Regular mode. The water stream dislodges stubborn food particles from bridges, crowns, or braces.
