Abstract: The composition presents itself in the form of rapidly dissolving water soluble tablets, which contain multivitamins, sodium percarbonate, sodium bicarbonate, citric acid, various food flavors and food dyes. These components are mixed in such percentage and weight proportions, that when placed in contact with human saliva, a pH of 5.4-5.6 is created within the oral cavity. A concurrent excretion of carbon dioxide (CO.sub.2) and oxygen (O) occurs. Both of these reactions enhance the desired effect, of cleaning both soft and hard tartar from the teeth, while at the same time diminishing not only the amount of pathogenic microflora, but also the inflammatory processes in the gum and mucus membrane. The end result is a significant prophylaxis of caries, achieved without any harm being done to the enamel of the teeth.The novel effect of the invention becomes apparent in that the offered composition can be utilized in either of two forms.
