The present invention provides a two-paste dental curable composition achieving clinically acceptable bond durability to dental adherends including dental glass ceramic restorations (particularly lithium disilicate-containing glass ceramic restorations) without using conventionally used primers. The present invention relates to a two-paste dental curable composition comprising: a first agent comprising a polymerizable monomer (a) having an acid group, a polymerizable monomer (b) having no acid group, a polymerization initiator (c), and a filler (d)； and a second agent comprising a polymerizable monomer (b) having no acid group, at least one filler (e) selected from the group consisting of a basic glass filler and alumina, a polymerization accelerator (f), and a silane coupling agent (g) represented by the following general formula [I]:(The definitions of the symbols are omitted.)
