A dental curable composition includes a polymerizable monomer (A), a filler (B), and a polymerization initiator (C). The polymerizable monomer (A) contains a polyfunctional (meth)acrylic monomer (A-1) having no aromatic ring but having a moiety (X) constituted by an alkoxylene repeating unit having 1 to 15 carbon atoms, and a polyfunctional (meth)acrylic monomer (A-2) having an aromatic ring but no hydroxyl group. The moiety (X) has a C/O of 2.5 to 10 as a ratio of a total number of carbon atoms to a total number of oxygen atoms in the moiety (X). The moiety (X) has a backbone with a total of 25 to 60 constituent carbon atoms and oxygen atoms altogether. A content of the polyfunctional (meth)acrylic monomer (A-1) is 3 to 60 parts by mass in 100 parts by mass of the polymerizable monomer (A).
