The present invention provides a dental curable composition that can be favorably used with a resin-reinforced glass ionomer cement and that exhibits a superior sustained release of calcium ions as well as fluorine ions. The present invention pertains to a dental curable composition containing (A) fluoroaluminosilicate glass particles, (B) a mixture of (B1) acidic calcium phosphate particles and (B2) basic calcium phosphate particles or (B3) calcium compound particles excluding phosphorus, (C) polyalkenoic acid, (D) a polymerizable monomer that does not have an acidic group, (E) water, and (F) a polymerization initiator, wherein the dental curable composition contains, per a total of 100 parts by weight of (A) the glass particles and (B) the mixture, 30-99 parts by weight of (A) the glass particles, 1-70 parts by weight of (B) the mixture, 1-60 parts by weight of (C) the polyalkenoic acid, 5-90 parts by weight of (D) the polymerizable monomer that does not have an acidic group, 1-40 parts by weight of (E) water, and 0.01-20 parts by weight of (F) the polymerization initiator.
