Toothpaste formulations having dispersed therein a plurality of agglomerated particles of dental polishing agent that are visible, palpable and substantially insoluble in the toothpaste are disclosed. The agglomerates comprise individually impalpable particles of water insoluble dental polishing agent; can include an agglomerating agent and are reduced to smaller sized particles of dental polishing agent when subjected to mild mechanical agitation such as toothbrushing. Such agglomerates are particularly well suited for incorporation into transparent gel dental vehicles to provide special effects such as supplemental cleaning and polishing characteristics without adversely affecting the visual clarity of the finished toothpaste.
