Peroxide only whitens natural tooth structure. Veneers, crowns, bonded fillings, and implants keep their original color throughout a whitening treatment.
That has one important practical consequence: whiten first, then have any front-tooth restoration matched to your new shade. Whitening after a veneer is placed will leave the veneer looking darker than the surrounding natural teeth.
