The inclusion of dentistry in the Family Health Program aimed to reorganize the care model, expanding the population's access to oral health services, ensuring comprehensive care through the establishment of territorial bond. In this context, the study aimed to evaluate the profile of dental surgeons inserted into the program and analyze the working process of the dental team in three municipalities in the mountain region of the State of Rio de Janeiro, investigating whether it replaced the traditional model of service, by that focused on the SUS principles. This is an exploratory study based on interviews. The profile of the dental surgeon found in these municipalities showed potential for the transformation of practices in oral health, but the analysis of the labor process identified little involvement of these professionals with the community life conditions and difficulty to work in multidisciplinary teams. It pointed out the need for public policies that incorporate training programs for the dental surgeon to act in line with the guidelines of the Family Health Program.
