The EW1311 oral irrigator in the trendy mint green color removes food particles from between teeth and flushes out floating plaque from gum pockets. With three levels of water pressure intensity, the oral irrigator promotes blood circulation in the gums through gentle massage pressure. You can choose between a powerful or gentle water jet according to your preference. The water jet 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 jet dislodges stubborn food particles from bridges, crowns, or braces.
