A composite toothpaste product comprising a toothpaste containing a hydroxyapatite as a main active ingredient and another toothpaste containing a fluorine compound as a main active ingredient, which are enclosed with a container made of, for instance, a flexible tube but separated from each other by a partition united to the container. In the composite toothpaste product, the toothpastes are separated from each other with no contact when it is out of use, and are squeezed out of the container, when in use, in such a manner that the latter toothpaste is enclosed with the former. It is far more effective in removing bacterial plaque, improving tooth whiteness, and preventing dental caries than the conventional toothpaste products containing only either a hydroxyapatite or a fluorine compound.
