This study aimed to theorize, by means of social actors’ conception, about the reasons for the non-inclusion of oral health in the Family Health Strategy (FHS) in the city of Juiz de Fora, Minas Gerais, Brazil. This is a qualitative, exploratory, descriptive, and analytical study based on the grounded theory methodology and the National Oral Health Policy. Eleven interviews were performed with public managers, delegates who participate in the municipal health council, and dental surgeons who belong to the public health service. The theorization of the study was created through the data analysis process, which resulted in “a consequence of the dominant disease-centered oral health care model” as the main category. Data were categorized according to a methodological framework. The health concept set forth by local social actors contributed to the non-inclusion of oral healthcare teams (OHTs) in the FHS. This theorization identified the origins of the studied phenomenon and can aid in future policy decision-making carried out by local social actors.
