Crowns and veneers can’t be whitened, that is why many people undergo teeth whitening treatment before their treatment of dental crowns or veneers. No level or extent of whitening can change the color of dental crowns or veneers. The natural color of teeth is determined genetically and established at birth. Consequently, individuals may have varying shades of teeth, with some naturally having whiter teeth than others. It's important to note that teeth whitening procedures can only eliminate teeth staining that has accumulated over time and are unable to alter the intrinsic color of the teeth.
