Abstract Background Public health in Brazil has undergone major changes in recent decades. Objective To describe the overview of dental production performed by the Brazilian Unified Health System from 1999 to 2017 in Brazil and its macroregions. Method Data were obtained from the Outpatient Information System (SIA/SUS) and from the Brazilian Institute of Geography and Statistics (IBGE). Procedures rates (per 100,000 inhabitants per year) were established in each macroregion: restorative, prosthetic, collective, endodontic, exodontia, periodontic and preventive procedures. Statistical analysis of the time series was performed using a regression linear model. Results Prosthetic and periodontal procedures were the only ones with a positive linear trend in all Brazilian macroregions (p<0.001). Endodontics did not show a positive trend in Brazil (p=0.173). Restorations showed a growth in the North (p=0.003) and Center-west (p<0.001) macroregions. Exodontia presented a tendency to increase in the North macroregion (p=0.046), while the Midwest presented a decrease of it (p=0.049). Preventive (p=0.042) and collective (p=0.017) procedures showed a decrease in their production during the period. Conclusion Oral health showed great growth within the single health system in the 19 years evaluated. Periodontal procedures and dental prostheses were those with the highest growth trends.
