The present invention provides a dental curable composition that shows fluorescence sufficient to enable highly aesthetic harmonious restoration almost indistinguishable from surrounding natural teeth, and that, while having sufficient mechanical strength and radiopacity and good ease of polishing as a restorative material, desirably resists discoloration not only in the intraoral environment but under accelerated heating conditions and under xenon light, without losing fluorescence even under these conditions. The present invention also provides a cured product of such a dental curable composition. The present invention relates to a dental curable composition comprising a polymerizable monomer (A), an inorganic filler (B), a polymerization initiator (C), and a fluorescent agent (D), wherein the fluorescent agent (D) comprises a 9- to 11-membered benzo-fused heterocyclic compound containing two or more heteroatoms (excluding benzoimidazole compounds).

To provide a dental photocurable composition which can exhibit excellent mechanical characteristics even after returning from a low temperature to room temperature. To provide a dental photocurable composition, comprising (A) polymerizable monomer, (B) photosensitizer, (C) photoacid generator and (D) photopolymerization accelerator and the (C) photoacid generator may include only (C-1) iodonium salt-based compound of an anion having log S of −4 or less.

A method that includes the step of using a person's fingers to push a dental composition into engagement with a damaged tooth surface of a damaged tooth thereby adhering the dental composition to the damaged tooth surface and covering at least a portion of the damaged tooth surface. The dental composition includes a base material comprising at least one of the following compounds chosen from the group consisting of: a product consisting of one or more hydrocarbon-based waxes that may also include inorganic fillers and/or organic fillers; an uncured, uncrosslinked silicone high consistency rubber base; and a hydrophobic water insoluble solid material that is malleable at 37° C. or lower and safe for a human oral environment. The base material has at least one dry, powdered hydrophilic polymeric substance engaged with and dispersed on one or more surface of the base material.
