A dental restorative composition comprises: (A) polymerizable monomer(s) selected from hydroxyethyl (meth)acrylate phosphate, hydroxypropyl (meth)acrylate phosphate, hydroxybutyl (meth)acrylate phosphate, dipentaerythritol penta(meth)acrylate phosphate, pentaerythritol tri(meth)acrylate phosphate, phenyl (meth)acryloxyethyl phosphate, and a combination thereof; (B) polymerizable monomer(s) having a molecular weight of 100-250, at least one hydroxyl group, and at least one ethylenically unsaturated group; (C) polymerizable monomer(s) having a molecular weight of 270-900, at least two ethylenically unsaturated groups and no acidic functional group; (D) photo-initiator(s); and (E) filler(s) each having a mean particle size of more than 0.005 microns and less than 70 microns. The weight ratio of (A+B):(C) ranges from 30:70 to 90:10, and the composition has a shear bond strength of at least 10MPa to both dentin and enamel after being light-cured.
