Abstract
A handheld portable oral cleaning device that includes a refillable internal bladder, which a user is able to fill with a liquid. The bladder is preferably an expandable but resilient latex rubber. One end of the bladder is accessible to the user, such that the user may fill the bladder with a liquid, such as water from a faucet. As the bladder fills with water it expands and exerts a pressure on the water as the bladder has a tendency to return to its original unfilled form. The pressurized water may then be sprayed out of the oral cleaning device to assist in cleaning the user's mouth.
