Objective: This study aimed to evaluate correlation between the number of children and the period that each participants had breastfeeding and periodontal disease. 
Methods: Data of 3,232 female adults were derived from The Sixth Korea National Health and Nutrition Examination Survey, which was conducted in 2015. The complex sample survey data analysis was performed using a statistic program. The chi-square test and logistic regression analysis were performed to scrutinize effects of breastfeeding to permanent tooth caries and periodontal disease.
Results: Chi-square analysis revealed that the association between breastfeeding period and permanent tooth caries experience was not significant. Association between the number of children breastfeed and permanent tooth caries experience was not statistically relevant as well. On the other hand, chi-square analysis for the correlation between breastfeeding period and number of children breastfeed, and periodontal disease showed statistical significance (p<0.05). 
Conclusion: This study confirmed the effects of breastfeeding to periodontal disease in Korean female adults. Tooth brushing instruction, occasional dental check and panorama taking should be encouraged to decrease the risk of periodontal disease.
