PROBLEM TO BE SOLVED: To provide a dentifrice which can effectively remove stains such as dental plaque, colored stains, and the like adhered to teeth without being influenced by the size of irregularities of the surface of the teeth.SOLUTION: There is provided the dentifrice that contains 2 mass% or more and 40 mass% or less of granules (A) which has a particle diameter of 45 &mum or more, and which comprises the following granules: (a1) granules whose particle diameter is 45 &mum or more and less than 63 &mum: (a2) granules whose particle diameter is 63 &mum or more and less than 90 &mum (a3) granules whose particle diameter is 90 &mum or more and less than 125 &mum (a4) granules whose particle diameter is 125 &mum or more and less than 150 &mum (a5) granules whose particle diameter is 150 &mum or more and less than 180 &mum and (a6) granules whose particle diameter is 180 &mum or more. In the granules (A), the volume ratio of the content of the granules (a2)-(a4) and granules (a6) is a specific value, and the collapse strength of the granules is 0.1 g/granule or more and 15 g/granule or less.【課題】歯の表面に存在する凹凸の大きさに左右されることなく、歯に付着した歯垢や着色汚れ等の汚れを効果的に除去することのできる歯磨剤に関する。【解決手段】粒径が45μm以上であって、次の顆粒(a1)粒径が45μm以上63μm未満の顆粒、(a2)粒径が63μm以上90μm未満の顆粒、(a3)粒径が90μm以上125μm未満の顆粒、(a4)粒径125μm以上150μm未満の顆粒、(a5)粒径150μm以上180μm未満の顆粒、及び(a6)粒径180μm以上の顆粒からなる顆粒(A)であって、顆粒(a2)~(a4)及び顆粒(a6)の含有量の体積比が特定の値であり、かつ顆粒の崩壊強度が0.1g/個以上15g/個以下である顆粒(A)を2質量%以上40質量%以下含有する歯磨剤。【選択図】図1
