This procedure involves whitening teeth to remove any discoloration or stains on tooth enamel. There is a wide variety of procedures for teeth whitening that can be performed on the dental chair, at home or with a combination of both, depending on the patient’s preferences and budget. However, teeth whitening only works on the natural enamel of teeth, so any implants, fillings, crowns or veneers will not discolor and may end up having a different color shade.
