A teething device for exercising gums and deciduous teeth. Two hollow receptacles sealingly mate to form a body of the teething device. A plurality of hollow knobs extend outwardly from the receptacles. The hollow interior of each knob is in a fluid communication with the interior space of the teething device. The teething device may be filled with a cold liquid to cool the exterior surfaces of the knobs. The liquid may be periodically discarded, and the hollow interior of the teething device may be refilled with a liquid of a predetermined temperature.
