Highlights • Proportion of the enamel layer affected by short tooth bleaching is unknown. • After a short bleaching, enamel components were analyzed from the surface inward. • At the surface, a gradient of probability of changes followed the order: mineral > organic > water > permeability. • Probability of changes decreased from the surface inward, but followed the same order seen at the surface. • Despite negligible proportion of affected enamel layer, tooth shade changed significantly.
