Abstract
Abstract A toothbrush assembly having a handle, a brush assembly releaseably interconnected with one end of the handle, and a massaging device connected with a second end of the handle. The brush assembly has a cylindrical base shaped to be received in a recess in the end of the handle and has an array of bristles arranged to provide a concave brushing surface. The massaging device includes a carrier having a container of liquid positioned in an internal cavity of the carrier. The container is positioned so as to be broken and dispense its contents when an end of a toothbrush is inserted into the carrier. A porous, absorbent material forms an outer surface of the device and absorbs the liquid for application to the gums of a user.
