The present inventors have tried to prepare a composition for multifunctional dental gum beneficial to remove bad breadth and prevent the tartar. The present invention is to provide a chewing gum capable of preventing dental damage due to an increase in pH while food is digested in the mouth after eating, being harmless to the human body even though several natural compositions for preventing and alleviating periodontal diseases are used for a long time, and continuously maintaining antibiotic and buffering effects, thereby having excellent effects in preventing periodontal diseases and removing bad breadth. According to the present invention, a stevia extract as a natural sweetener is used instead of sweeteners used in the existing sugarless gum in order to remove the tartar or prevent bad breadth, thereby solving a problem of the occurrence of bowel disease or diarrhea. Further, the functional gum of the present invention can have improved taste and flavor, and improve the health of oral cells and gum due to its anti-oxidant effect. Further, the functional gum of the present invention can minimize the composition of polysaccharides such as sugar to significantly lower the calories, so that even diabetic patients can enjoy the function gum. In order to help the continuous release of dental constituents by fluoride ions and phosphate ions, zeolite or calcium carbonate, or calcium phosphate is allowed to adsorb on an insoluble carrier, thereby maximizing the ion release effect by saliva during the chewing of the gum. Further, in order to neutralize plaque acid, baking soda and sodium carbonate are mixed at a ratio of 1:1. Here, the compounds are dissolved in the saliva to function as a buffer solution for maintaining the alkaline pH level, thereby remarkably lowering the solubility of teeth in the acid.COPYRIGHT KIPO 2014본 발명은 껌을 씹게 됨으로써 구치제거 및 치석방지에 도움이 되는 다기능성 치과용 껌의 조성을 만들고자 하였다. 식사 후 음식물이 구강 내에서 분해되는 과정에서 발생하는 산도 증가에 의한 치아손상을 막고 치주질환의 예방 및 개전효과를 높일 수 있는 여러 가지 천연
