PROBLEM TO BE SOLVED: To provide an adhesive reinforcement film that easily and quickly repairs damage to a tooth and reinforces the tooth.SOLUTION: An adhesive reinforcement film 1a includes a photocurable resin 2 that is solidified by being irradiated with curing light (L) having a predetermined wavelength, and a film 3 to which the photocurable resin 2 is attached, and which transmits the curing light (L). The photocurable resin 2 is solidified by being irradiated with the curing light (L) in a state that the film 3 to which the photocurable resin 2 is attached is stuck to a tooth W1 so as to reinforce the tooth W1.SELECTED DRAWING: Figure 3【課題】簡易にかつ迅速に歯の損傷を修復して補強する粘着補強フィルムを提供する。【解決手段】所定の波長の硬化光（Ｌ）を照射して固化させる光硬化樹脂２と、光硬化樹脂２が着設され硬化光（Ｌ）を透過するフィルム３と、を備え、光硬化樹脂２が着設されたフィルム３を歯Ｗ１に貼着した状態で硬化光（Ｌ）を照射して光硬化樹脂２を固化させて歯Ｗ１を補強する粘着補強フィルム１ａを構成した。【選択図】図３
