The inventive device object of the present application is an innovative automatic toothbrush that fits like a mouth guard between the user's top and bottom teeth. Moving bristles will clean all around each tooth at the same time, so teeth can be cleaned well and in less time than using a conventional toothbrush. Omnibrush is a revolutionary new way to have enhanced dental care. It fits around the top and bottom teeth like a mouth guard. There are bristles for the outside, the inside and the tops and bottoms of each individual tooth. While positioned comfortably within the mouth, the bristles will work automatically to clean every tooth thoroughly. The unit is electrically powered, using a charger or rechargeable batteries. The cleaning bristles can be replaced when they become worn, eliminating the need to replace the whole cleaning unit. It will be available in a small size so children can use it as well.
