We use a shade chart to match the color of your porcelain veneers to the color of your adjacent natural teeth. Before we select that color to match, we usually like to have your teeth whitened to return them to their natural whiteness without stains. From that point forward, that will be the barometer of your tooth color.
Your new porcelain veneers will match that natural white color, and they will not stain. However, your natural teeth will stain, especially if you drink coffee or red wine, and eat certain foods. If your color becomes variable between your teeth with veneers and your other teeth, you can have whitening done on your non-veneered teeth to bring them back to match your brighter veneers.
