Dental Whitening: What to Know Before You Start
Whitening products vary in strength, application method, and supervision. Before whitening, it is helpful to know whether discoloration is likely to respond and whether your teeth and gums are healthy.
Natural teeth and restorations respond differently
Whitening changes natural enamel but does not bleach crowns, veneers, or tooth-colored fillings.
Overuse can increase sensitivity
Follow product directions and dental recommendations. More product or longer exposure is not automatically better.
Children and teens need professional guidance
Whitening decisions for younger patients should be discussed with a dentist based on age, tooth development, and the cause of discoloration.
