Abstract: A stabilized and extrudable paste or gel dentifrice comprises two dentifrice portions, each of which includes a component which is chemically reactive with the other such component in the other portion, with the portions being maintained separate from each other in a dispensing container from which they are dispensable together through a closable opening therein in response to pressure. One of the reactive components is an alkali metal fluorine-containing salt such as sodium fluoride or sodium monofluorophosphate, used for its effect in hardening tooth enamel, and the other is a water insoluble calcium salt, such as dicalcium phosphate, tricalcium phosphate or calcium carbonate, used as a polishing agent. The dentifrice portions are preferably separated by an extrudable material, such as a polyhydric alcohol-water gel of a gum, such as sodium carboxymethyl cellulose. Also within the invention is a method for the manufacture of the mentioned dentifrice.
