Abstract A dental cream or toothpaste having dispersed therein particles of a water-insoluble thermoplastic polymeric material that are (a) visible because of their size and contrasting appearance, (b) substantially insoluble in the toothpaste base and (c) impalpable in the mouth during brushing of the teeth. A speckled toothpaste having dispersed therein particles of a blend of water-insoluble thermoplastic material and pigment that (a) are visible because of their size and contrasting appearance, (b) are substantially insoluble in the toothpaste base, (c) are impalpable in the mouth during brushing of the teeth and (d) have below 5% pigment concentration and a ratio of thermoplastic material to pigment of at least 20:1. A toothpaste comprising a clear gel base having dispersed therein a dental polishing agent having substantially the same refractive index as the clear gel base and visible particles of water-insoluble thermoplastic material contrasting with the gel base.
