A dental curable composition includes: a radically polymerizable monomer; a polymerization initiator; and a hyperbranched polymer, in which the hyperbranched polymer includes a unit structure represented by the general formula (I) and unit structures represented by the general formula (IIA) and/or the general formula (IIB) (in the general formula (I), A represents a single bond for bonding C and R 1 , >;C=O, -O-, or -COO-, R 1 represents a divalent saturated aliphatic hydrocarbon group or a divalent aromatic hydrocarbon group, and R 2 represents a hydrogen atom or a methyl group; and in the general formula (IIA) and the general formula (IIB), R 3 , R 4 , and R 5 each represent a hydrogen atom, an alkyl group, an alkoxycarbonyl group, an aryl group, or a cyano group, and R 6 represents an alkylene group).
