The importance of oral health care in respiratory infections has been highlighted in the past. Several recent studies have revealed the association between COVID-19 and oral health. This paper aims to comprehensively analyse the risk of COVID-19 with respect to oral health. The search was performed on 12 July 2021 using Embase and Medline. Cohort, case-control, and cross-sectional studies were included in this study. The Newcastle-Ottawa scale was used to qualitatively assess the risk of bias. The data were used for the odds ratio calculation, followed by the unadjusted value and 95% confidence interval. Five studies (one cohort, one case-control, and three cross-sectional studies) considered in this review included 16,721 participants. In the group with poor oral health, the incidence was 1.97 (0.93~4.16), the severity was 14.01 (4.89~40.20), the hospitalization rate was 2.01 (1.2~3.07), and the mortality was 1.41 (0.64~3.11) times higher than in the group with good oral health. Poor oral health increases the risk of COVID-19. To reduce the risk of COVID-19, comprehensive oral management guidelines are urgently required. Policymakers should establish appropriate countermeasures according to the national situation.
