The interdisciplinarity of prenatal oral health care represents a strategy for an integral during pregnancy, valuing the interprofessional context and the collective view of health, in accordance to the guidelines of the Brazilian Unified Health System. The objective of this study was, through an integrative review, to map and analyze the scientific literature on the occurrence of interprofessional collaborations for the feasibility of prenatal oral health care in Primary Health Care. As a method, a systematic search of primary articles was carried out in the databases: BVS, BVS Dentistry, Scielo, Pubmed, Scopus, Periódicos Capes, Web of Science and MEDLINE Complete (EBSCO)3 using the Decs/Mesh related to "Attention Primary Health", "pregnant women" and "prenatal dental care", without time restriction. The eligibility criteria of the studies were the Brazilian scientific productions referred to dental care in prenatal care, which included primary health care professionals and / or pregnant women who attended prenatal care in the primary health care. As a results, 20 articles were included, systematized into three categories, showing barriers, potentialities, and recommendations for the feasibility of the prenatal oral health care in primary health care. In conclusion, interdisciplinary collaborative dialogues were perceived as deficient /absent among prenatal professionals, managers and pregnant women. This gap makes it difficult to exchange knowledge, strengthen bonds, deconstruct fears, reducing the adherence to the prenatal oral health care by pregnant women. Strategies to implement this interprofessional collaborative work are necessary, such as: well-articulated communication and guiding flows between professionals, shared agendas for the care of pregnant women, spaces for interdisciplinary health education and permanent education in the team.
