Introduction: Fluoride concentration values in water must be inserted in an information system; however, no protocol was proposed to perform the verification of the inserted data. Objective: To present a proposal to critically review fluoride concentration data in order to provide reliability of information production on water fluoridation surveillance. Method: The fluoride concentration monitoring data from the water supply systems of the State of São Paulo registered in the year 2015 in the Surveillance Information System of the Water Quality for Human Consumption were used. A proposal was applied using Excel® software. Results: The database was reduced from 23,840 registers of fluoride concentration distributed in 586 municipalities to 22,807 distributed in 543 municipalities. Notation errors, underreporting during the year, municipalities with 50% or more of the samples equal to 0.000 mg F/L or with standard deviation equal to 0.000 mg F/L, and outliers were the main critical factors. Conclusions: The application was simple, feasible and could be routinely adopted by the surveillance agencies.
