Objective: Dental hypomineralization such as dental fluorosis has increased in recent times, which leads to unaesthetic appearance of teeth visible at close quarters. There are different treatment possibilities to improve the aesthetic appearance of hypomineralized enamel described in dental literature. The enamel microabrasion has been a feasible alternative, since it is a fast, safe, conservative, and easy to perform, which promotes good esthetic results.  oreover, this technique is a conservative method that improves the appearance of the teeth without causing significant structural loss. The association of different techniques, such as dental bleaching, can provide good esthetic outcomes, but the etiology, intensity and depth of stain should be considered. Thus, the aim of this article is to describe an easy technique for managing mild to moderate dental fluorosis using microabrasion in association with dental bleaching.Case Report: First, application of the microabrasion material on the enamel surface was performed with 6% hydrochloric acid and silicon carbide and then with 37% phosphoric acid and pumice paste. Subsequently, dental bleaching employing 10% carbamide peroxide gel was indicated.Conclusion: This conservative approach may be considered an interesting alternative treatment to remove fluorosis staining and to improve aesthetic appearance.
