PROBLEM TO BE SOLVED: To easily manufacture a dentition-compatible toothbrush capable of polishing a large number of teeth at a time with a small amount of polishing residue. A tooth row compatible toothbrush 10 is formed in a tooth row shape obtaining step of obtaining a three-dimensional shape of a user's tooth row 20, and an inner wall surface α having a shape following the surface of the user's tooth row 20. A brush base forming step of forming the brush base 11 having the formed tooth row insertion groove 11a based on the three-dimensional shape of the tooth row 20 acquired in the tooth row shape acquiring step, and a brush formed in the brush base forming step. It is manufactured by going through a flocking step of implanting a large number of bristles 12 having substantially the same length on the inner wall surface α of the tooth row insertion groove 11a in the base 11. [Selection diagram]【課題】 磨き残しが少ない状態で多数本の歯を一度に磨くことのできる歯列適合型歯ブラシを容易に製造する。【解決手段】 歯列適合型歯ブラシ１０を、使用者の歯列２０の三次元形状を取得する歯列形状取得工程と、内壁面αが使用者の歯列２０の表面に倣った形状に形成された歯列挿入溝１１ａを有するブラシ台１１を、歯列形状取得工程で取得された歯列２０の三次元形状に基づいて成形するブラシ台成形工程と、ブラシ台成形工程で成形されたブラシ台１１における歯列挿入溝１１ａの内壁面αに、長さが略等しい多数本の毛１２を植え付ける植毛工程とを経ることによって製造する。【選択図】 図２
