The invention provides a dental coating kit with high adhesiveness to teeth that contains a primer composition including an acidic group-containing polymeric monomer (a), water (b) and a water-soluble solvent (c) and a surface smoothing composition including a polyfunctional polymeric monomer (f), a volatile solvent (g) and a photopolymerization initiator (h); and a dental coating kit with high adhesiveness to teeth and minimally suffering from chipping and peeling off that contains a primer composition including an acidic group-containing polymeric monomer (a), water (b) and a water-soluble solvent (c), a coating composition including a polymeric monomer (d) and a photopolymerization initiator (e), and a surface smoothing composition including a polyfunctional polymeric monomer (f), a volatile solvent (g) and a photopolymerization initiator (h). Either dental coating kit is particularly useful as a kit for preventing stain and color return of a bleached tooth.
