An abrasive mouthwash composition which comprises
- a) 0.1 to 50% by weight of dentally acceptable abrasive;
- b) 0.01 to 5% by weight of synthetic or natural clay;
- c) 0.1 to 5% by weight of surfactant;
- and
- d) at least 45% of a liquid carrier,
- in the form of a pourable suspension having a viscosity (Brookfield) of 1-2000 cps,
- said liquid carrier having an emulsion or micro-emulsion of levels of flavoring agents having a high flavor impact, and containing at least 5% by weight water, at least 5 percent by weight of humectant selected from the group consisting of glycerin, sorbitol, propylene glycol, polyethylene glycol and mixtures thereof, up to 5% by weight silicone oil, up to 35% by weight of alcohol, said clay suspending agent maintaining said solid abrasive particles in a substantially physically stable pourable mouthwash during storage, without over-thickening, said pourable abrasive mouthwash having a mildly abrasive action on the teeth when rinsed around in the mouth, when used with or without a toothbrush, or as a pre- or post-brushing rinse with the toothbrush, said abrasive in said composition having an radioactive dentine abrasion value (RDA) of about 30 to 200.
