In modern society, drinking is becoming a culture while alcohol consumption continues to increase. Studies show that alcohol consumption in the oral cavity averages 2 hours, and alcohol consumption seems to have a
high effect on tooth damage. Therefore, this study was conducted to evaluate the possibility of dental erosion due to intake of some alcoholic beverages in the market. Six types of alcoholic beverages were immersed in 1 ml of each alcohol for 10 min, 60 min, and 120 min to obtain only enamel of the tooth and observe changes over time. The crystal structure of the enamel surface was observed by scanning electron microscopy (SEM), and the changes in calcium and phosphorus, the major constituents of teeth, were analyzed by energy dispersive electromagnetic wave (X-ray) spectroscopy (EDS). Based on the results, the tooth showed a destructive pattern while and loss of calcium (Ca) and phosphorous (P) increased significantly as exposure time to the low pH alcoholic drinks increased. Since this causes the demineralization of inorganic components and greatly affects the risk of tooth erosion, long contact with alcohol should be avoided.
