A nursing bottle for automatically rinsing a baby's teeth by independently dispensing first and second liquids, includes a nursing bottle having a nipple, a rinsing device having a dispensing end and a buoyant valve attached to the dispensing end for retaining the second liquid within the rinsing device while the nursing bottle receives the first liquid. The valve retains the second liquid within the rinsing device when the bottle is at least substantially inverted due to a buoyant force produced by the valve against the dispensing end. The buoyant force of the valve is greater than the force of gravity which acts on the valve until the first liquid is substantially dispensed from the bottle. After which, the force of gravity overcomes the buoyant force of the valve and the valve is pulled towards the nipple by the force of gravity. As a result, the valve automatically releases the second liquid from the rinsing device and into the nipple to rinse the baby's teeth.
