A topic that has been less researched on, especially in Romania, is the identification of gender differences in oral health. The present scientific research used an online survey to assess the attitudes (dental beliefs survey-R/R-DBS), the values (oral health values scale/OHVS), the behaviours (dental neglect scale/DNS), and the literacy (oral health literacy scale/OHLS) related to oral health and to dental professional services in the case of a sample of 600 Romanian adults (Meanage = 30.84). The relation between the level of knowledge as a predictor of attitudes and values related to oral health was analysed by the means of a structural equation based on the partial least square method (PLS-SEM). The results show that women have more positive attitudes towards dental medical services, higher oral health values, better self-care behaviours, and higher oral health literacy than men. In the case of men, attitudes and behaviours related to self-care are influenced by their oral health literacy and level of education; in the case of women, the latter are influenced only by their level of oral health literacy. The impact that knowledge in oral health has on attitudes, values, and behaviours was highlighted. The differences in attitudes and values related to oral health between the two genders can be accounted for by the differences in formal and informal education (studies and oral health literacy, respectively).
