Professional teeth whitening is the ideal method of lifting the shade of your teeth. However, you should note that crowns, bridges, fillings, and veneers will not change color during the whitening process. If you have gum disease, worn enamel, cavities, or exposed roots, you may not be a suitable candidate for teeth whitening. Patients should always consult with a dentist before starting any whitening treatment so they can recommend the best option for their needs.
