Provided is a method for producing a curable composition for dental use, comprising mixing a polymerizable monomer (A), a spherical filler (B) having an average primary particle diameter that falls within the range from 230 to 290 nm, a spherical filler (C) having an average primary particle diameter that falls within the range from 100 to 500 nm and is different from that of the spherical filler (B), and a polymerization initiator (D) together. With respect to the number of particles constituting each of the spherical filler (B) and the spherical filler (C), 90% or more of the particles are present in a range of plus or minus 5% from the average particle diameter. The polymerizable monomer (A), the spherical filler (B) and the spherical filler (C) satisfy the conditions represented by the following formulae: nP <； nFB and nP <； nFC (wherein nP represents a refractive index of a polymer produced by polymerizing the polymerizable monomer (A) as measured at 25°C； nFB represents a refractive index of the spherical filler (B) as measured at 25°C； and nFC represents a refractive index of the spherical filler (C) as measured at 25°C) .
