This work is about the insertion of oral health in the Family Health Program - PSF identifying opinions, perceptions and necessities of the adult's patients from Vila Espanhola UBS (Health Basic Unity), São Paulo city, in relation to dental health and the service of attention to buccal health offered by the PSF. The methodology was qualitative research made of the following steps: systematic observation of the activities done by the buccal health team of the UBS, and interview with the adult patients, older than 18, that had any kind of attention in the past six months. In the analyses phase, we opted by the content analysis of Bardin. It was noticed that the insertion of PSF increased the access of the studied population in the UBS region, which increase brought a bigger demand by specialized oral services. The patients are not being able to have access to those secondary attentions in buccal health. Some dissatisfaction were detected: the constant changing of the dentists in the team - compromising the link, lack of patients' autonomy in relation to their own oral health, as the way how it is applied the equity principle to prioritize the cares. Then, the insertion of buccal health in the PSF brought some advances, however it needs to be reevaluated to really reach its main proposals as integrality of attention, equity among others needs.
