This article describes a technique used to treat superficial white spot lesions by a mini-mally invasive approach. The proposed technique is based on reactivation of enamel by elimination of its hypermineralized external layer through microabrasion, followed by daily home application of casein phosphopeptide–amorphous calcium phosphate complexes (CCP-ACP). The technique may allow elimination of white spot lesions without involving restorative procedures. Microabrasion followed by long-term daily home application of CCP-ACP may be considered an interesting alternative to the restorative approach for treatment of white spot lesions.
