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 R1, >；C═O, —O—, or —COO—, R1 represents a divalent saturated aliphatic hydrocarbon group or a divalent aromatic hydrocarbon group, and R2 represents a hydrogen atom or a methyl group； and in the general formula (IIA) and the general formula (IIB), R3, R4, and R5 each represent a hydrogen atom, an alkyl group, an alkoxycarbonyl group, an aryl group, or a cyano group, and R6 represents an alkylene group).
