A device for rinsing a child's mouth and teeth comprising a pliable vessel having a front end, a back end, and side walls defining a hollow interior space inside the vessel. The side walls contain a first depression near the front end and a second depression opposite the first notch. The first depression contains at least one front opening in fluid communication with the interior space, angled to face the front surface of the top teeth, and at least one back opening positioned closer to the front end from the front opening, in fluid communication with the interior space, angled to face the back surface of the top teeth. A removable cap to removably close the vessel mounted at the back end. When the vessel is filled with water and the front end is inserted into a child's mouth so that the first depression receives the portion of the top teeth and the child's second depression receives the portion of the child's bottom teeth, manually squeezing the vessel pushes water through the front opening and the back opening to rinse the portion of the top teeth and the mouth without directly rinsing the bottom teeth.
