A method for manufacturing a denture, comprising: preparing an artificial tooth (1, 1A) and a denture base (3, 3A) provided with a concave socket (2, 2A) in which the artificial tooth (1, 1A) is embedded; applying an adhesive to the socket (2, 2A); and embedding the artificial tooth (1,1A) in the socket (2, 2A) to which the adhesive is applied, wherein multiple grooves (9, 10, 13, 9A, 10A) are provided on at least one of a surface of the artificial tooth (1, 1A) on the side embedded in the socket (2, 2A) and an inner surface defining the socket (2, 2A), wherein the multiple grooves (9, 10, 13, 9A, 10A) include a groove (9, 9A, 13) extending to the lingual side, and wherein the embedding the artificial tooth (1, 1A) in the socket (2, 2A) includes forming a discharge hole (11, 11A) exposing an end (9a, 9b) side of the groove (9, 9A, 13) extending to the lingual side from the denture base (3, 3A) to discharge the adhesive, and discharging the adhesive from the discharge hole (11, 11A), wherein preparing the artificial tooth (1, 1A) and the denture base (3, 3A) includes preparing the artificial tooth provided with a first groove and a second groove, the first groove extending from a basal surface to a lingual side surface of the artificial tooth, and the second groove extending from the basal surface to a buccal or labial side surface of the artificial tooth, wherein an end of the first groove extending on the lingual side surface is located on a crown side relative to a cervical line on the lingual side of the artificial tooth, and wherein an end of the second groove extending on the buccal or labial side surface is located on a root side relative to the cervical line on the buccal or labial side of the artificial tooth. preparing an artificial tooth (1, 1A) and a denture base (3, 3A) provided with a concave socket (2, 2A) in which the artificial tooth (1, 1A) is embedded; applying an adhesive to the socket (2, 2A); and embedding the artificial tooth (1,1A) in the socket (2, 2A) to which the adhesive is applied, wherein multiple grooves (9, 10, 13, 9A, 10A) are provided on at least one of a surface of the artificial tooth (1, 1A) on the side embedded in the socket (2, 2A) and an inner surface defining the socket (2, 2A), wherein the multiple grooves (9, 10, 13, 9A, 10A) include a groove (9, 9A, 13) extending to the lingual side, and wherein the embedding the artificial tooth (1, 1A) in the socket (2, 2A) includes forming a discharge hole (11, 11A) exposing an end (9a, 9b) side of the groove (9, 9A, 13) extending to the lingual side from the denture base (3, 3A) to discharge the adhesive, and discharging the adhesive from the discharge hole (11, 11A), wherein preparing the artificial tooth (1, 1A) and the denture base (3, 3A) includes preparing the artificial tooth provided with a first groove and a second groove, the first groove extending from a basal surface to a lingual side surface of the artificial tooth, and the second groove extending from the basal surface to a buccal or labial side surface of the artificial tooth, wherein an end of the first groove extending on the lingual side surface is located on a crown side relative to a cervical line on the lingual side of the artificial tooth, and wherein an end of the second groove extending on the buccal or labial side surface is located on a root side relative to the cervical line on the buccal or labial side of the artificial tooth.
