Tooth bleaching (carbamide or hydrogen peroxide; home and/or in-office) vs No bleaching (untreated or pH-cycling control)

Caries susceptibility, enamel demineralisation, erosion, or microhardness · Permanent teeth / enamel specimens (in vitro)

Low-quality in vitro evidence suggests that bleaching of permanent teeth does not increase susceptibility to caries, demineralisation or erosion (ungraded); the clinical question could not be answered because only in vitro studies were available.

Tooth bleaching (carbamide or hydrogen peroxide; home and/or in-office) vs No bleaching (untreated control)

Colour change / camouflage of white spot lesions (reduction of colour disparity between carious and sound enamel) · Permanent teeth with post-orthodontic white spot lesions (orthodontic patients and in vitro enamel specimens)

Bleaching may diminish colour disparities and camouflage post-orthodontic white spot lesions, but the certainty of the evidence is very low; the findings could neither support nor refute bleaching.
