PROBLEM TO BE SOLVED: To obtain a dental curable composition capable of achieving recovery with remarkably high color tone adaptability to a natural tooth and excellent in operability and low in polymerization shrinkage and having high flexural strength of a cured body and excellent in surface gloss and anti-abrassiveness. SOLUTION: This dental curable composition is produced by mixing a polymerizable monomer composition with an organic-inorganic composite filler having a particle mean diameter of 10-20μm and has diffusion degree D of >=0.01 defined by the following formula in a cured body. D=[(I20/cos 20 deg.)+(I70/cos 70 deg.C)]/(2×I0) (wherein, I0, I20, and I70 indicate each optical strength of light transmitted at angles of 0 deg., 20 deg., and 70 deg. with respect to the incident direction of light when light is vertically radiated to the surface of a sheet sample with a thickness of 0.3 mm obtained by curing of the dental curable composition).
