A dental curable composition comprises (A) a polymerizable monomer and (B) an organic amine-based polymerization initiator, wherein (A′) a long-chain polymerizable monomer having a chain length of 17 or more atoms is contained in the component (A) and/or (C) a soft resin material are/is contained in the composition, and when the amount (parts by weight) based on 100 parts by weight of the component (A) of the component (A′) is represented by [a′] and the amounts (parts by weight) based on 100 parts by weight of the total of the components (A) and (B) of the components (A), (B) and (C) are represented by (a), (b) and (c), respectively, 70≦(a)≦99.99, 0.01≦(b)≦5 30, 1≦[a′]/5+(c)/1, 0≦[a′]≦95, and 0≦(c)≦250.
