A method of restoring a tooth cavity is conducted by a direct or indirect method with a visible light curable nanocomposite of a dental restorative material with a low polymerization shrinkage, wherein the dental restorative material comprises an epoxy resin, inorganic oxide nano particles, a photoinitiator and a photosensitizer. The direct method involves the filling of the tooth cavity with the nanocomposite dental restorative material, stacking the nanocomposite dental restorative material in the tooth cavity, and curing with visible light followed by shaping and polishing. The indirect method involves making a mold of the tooth, casting the mold with the nanocomposite dental restorative material, curing with visible light followed by shaping and polishing, then removing the shaped and polished material and adhering it to the tooth cavity.
