The present disclosure related to an oral composition, and more particularly, to an oral composition for reducing
tooth sensitivity. More specifically, the oral composition contains
zinc and a
copper salt capable of occluding dental tubules by agglomerating proteins, contributing to the reduction effect of
tooth sensitivity, and to maintain this, allows a
water soluble or
alcohol soluble polymer to coat the dental tubules and be maintained for a long time, thereby solving the main cause of
tooth sensitivity, as a result, providing an effect on the prevention or reduction of symptoms of tooth sensitivity in a short time. Furthermore, the oral composition according to the present disclosure contains a
copper salt or a
zinc salt which reacts with dental
tubule fluid to form a
protein complex, and contains
dicarboxylic acid or its salt which reacts with an inorganic matter such as
calcium to form a complex to induce
occlusion of dental tubules and dramatically increase the
occlusion effect, producing an effect on efficient prevention or reduction of tooth sensitivity symptoms in a short time. In addition, the oral composition according to the present disclosure contains
dicarboxylic acid and its salt which forms a
calcium complex in the mouth to induce
occlusion of dental tubules, and further contains a partially soluble
calcium salt and / or
phosphate to dramatically increase the
occlusion effect of the dental tubules, producing an effect on the efficient prevention or reduction of tooth sensitivity symptoms in a short time.
