The present invention provides a dental composition exhibiting both an excellent light diffusion property and excellent transparency, and having high mechanical strength and surface smoothness and gloss after polishing as a cured product and good handling properties as a paste. The present invention is a dental composition including: a polymerizable monomer (A); and an amorphous powder (B). The amorphous powder (B) has an average particle size of 1 to 20 µm, and includes silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The difference in refractive index between the cured product of the polymerizable monomer (A) and the amorphous powder (B) is 0.005 to 0.03.
