Abstract Although in‐office bleaching has been proven successful for bleaching teeth, controversy exists from morphological alterations in enamel morphology due to mineral loss and tooth sensitivity. This preliminary study aimed to evaluate the efficacy of a novel in‐office tooth bleaching technique modified with a casein phosphopeptide‐amorphous calcium phosphate (CPP‐ACP) paste (MI paste—MI) and its effect on the enamel morphology and tooth sensitivity. Three patients received a 35% hydrogen peroxide (Whiteness HP—HP) dental bleaching system. HP was prepared and applied on the teeth on one of the hemiarches, whilst teeth on the other hemiarch were bleached with a mixture of HP and MI. Tooth color, epoxy resin replicas, and sensitivity levels were evaluated in the upper incisors. The results were analyzed descriptively. Right and left incisors showed similar color change after bleaching. Incisors bleached with the mixture of HP and MI presented unaltered enamel surfaces and lower sensitivity levels. The currently tested tooth bleaching technique did not reduce the gel effectiveness while decreasing hypersensitivity levels and protecting the enamel against surface alterations caused by the high‐concentration bleaching peroxide tested. The concomitant use of MI Paste and high‐concentration hydrogen peroxide might be a successful method for decreasing tooth sensitivity and limiting changes in the enamel morphology during in‐office bleaching.
