Introduction: In the State of São Paulo, the concentration of fluoride in the public water supply should be maintained in the range of 0.6 to 0.8 mg/L, in order to prevent caries and avoid the risk of fluorosis. Objective: To evaluate the concentration of fluoride in public water supply in the municipalities covered by the Bauru Sanitary Surveillance Group. Method: Data were extracted from the routine of the Adolfo Lutz Institute – Bauru, from 38 municipalities monitored by the Proágua Program, in the period 2007–2016. Laboratory analyses were performed using the potentiometric method with ion-selective electrode and the interpretation of the results was based on Resolution SS-250/95 and the classification proposed by the Collaborating Center of the Ministry of Health in Oral Health Surveillance (CECOL) Results: Of the 8,887 samples analyzed, 31.1% had inadequate levels of fluoride ions, with 22.7% being below and 8.4% above the limit established by the legislation. According to the CECOL proposal, 59.4% of the samples showed maximum benefit for caries prevention and 0.6% revealed a very high risk for the production of dental fluorosis. Conclusions: These data point out the need to improve the operational control of the fluoridation process and emphasize the importance of water quality surveillance.
