A toothbrush body includes a handle connected to a head and bristles projecting from the top of the head. An open channel runs longitudinally along the body between a first open end and a second closed end such that the first open end is in communication with the second closed end through the open channel. The open channel, the first open end, and the second closed end are arranged so that a substantially downward running stream of water directed into the first open end is redirected through the channel and out of the closed second end to form a fountain. A direction of a flow of the fountain at the other of the first opening and the second opening has an upward component so that a user, i.e., holder of the toothbrush, can use the fountain for oral rinsing.
