Which product is NOT typically used as a dentifrice/oral cleansing agent?

Metronidazole is not typically used as a dentifrice or oral cleansing agent because it is primarily an antibiotic and antiprotozoal medication. It is employed in the treatment of bacterial infections and certain parasitic infections and works by inhibiting the growth of specific types of bacteria primarily in the gastrointestinal tract. In contrast, a dentifrice or oral cleansing agent is specifically formulated for cleaning teeth and promoting oral hygiene, focusing on plaque removal and the overall maintenance of oral health.

Products like C.E.T. (which often refers to a specific veterinary dental chews or toothpaste), Oxydent, and pet toothpaste are all designed to support oral hygiene by providing cleaning agents that help in reducing plaque and tartar buildup and freshening breath. These formulations often contain abrasives, flavoring agents, and other ingredients that aid in cleaning teeth and gums.
