Introduction: The possibility of intervening in the dissolution of enamel, significantly reducing the loss of minerals, and of reversing the progress of demineralization makes fluoride an essential aid to oral health. Objective: To evaluate the effectiveness of high-fluoride dentifrice in decreasing the process of enamel demineralization. Material and Methods: Thirty samples of bovine enamel were confectioned, sanded, polished and tested for determining their initial Knoop hardness. The samples were randomly divided into 3 groups: PD – Placebo Dentifrice (dentifrice without fluoride), CD – Conventional Dentifrice (1,450 ppmF), and HFD – High-Fluoride Dentifrice (5,000 ppmF). To evaluate the dynamic process of demineralization, each group was subjected to pH cycling with demineralizing and remineralizing solutions. The samples were immersed for 6 and 18 hours respectively in those solutions for 5 days at 98.6ºF. The dentifrice corresponding to each group was diluted (1:3) and the samples were treated for 1 minute, twice a day. After cycling, a final microhardness analysis was performed, using ANOVA and Tukey's test (p
