The present invention relates to a composition for oral cavity, and more particularly to a composition for oral cavity for alleviating brutal teeth. The present invention has a zinc and copper salt that can agglomerate proteins and seal the dentinal tubules. To maintain and maintain the effect, the dentinal tubules are coated with a water-soluble or alcohol-soluble polymer. By maintaining for a long period of time, the root cause of the denture is solved, and the effect of preventing or alleviating the symptoms of the denture in a short period of time. Further, the oral composition according to the present invention includes a copper salt or a zinc salt having a property of reacting with dentinal tubule fluid to form a protein complex, and reacting with an inorganic substance such as calcium to form a complex. By containing an acid or a salt thereof, the occlusion of dentinal tubules is induced, the occlusion effect is remarkably increased, and the effect of preventing or alleviating the denture symptoms efficiently in a short period of time is achieved. Further, the composition for oral cavity according to the present invention induces blockage of dentinal tubules by containing dicarboxylic acid having a property of forming a calcium complex in the oral cavity and a salt thereof, and partially soluble calcium salt and / or phosphoric acid. By further containing salt, the effect of blocking dentinal tubules is remarkably increased, and the effect of preventing or alleviating the denture symptoms efficiently in a short period of time is achieved.本発明は、口腔用組成物に関し、より詳しくは、しみ歯緩和のための口腔用組成物に関する。本発明は、タンパク質を凝集して象牙細管を封鎖できる亜鉛と銅塩を含むことでしみ歯緩和の効果を奏し、それを維持するため、水溶性またはアルコール溶解性高分子で象牙細管を塗布し長期間維持させることで、しみ歯の根本的な原因を解決して短期間でしみ歯の症状を防止または緩和する効果を奏する。また、本発明による口腔用組成物は、象牙細管液と反応してタンパク質複合体を形成する特性を有する銅塩または亜鉛塩を含み、カルシウムのような無機物と反応して複合体を形成するジカルボン酸またはその塩を含むことで、象牙細管の封鎖を誘導して封鎖効果を著しく上昇させ、短期間で効率的にしみ歯症状を防止または緩和する効果を奏する。また、本発明による口腔用組成物は、口腔内でカルシウム複合体を形成する特性を有するジカルボン酸及びその塩を含むことで象牙細管の封鎖を誘導し、部分溶解性カルシウム塩及び／またはリン酸塩をさ
