During your consultation and evaluation, your dentist also will note existing dental work, such as crowns and veneers, which will not respond to conventional whitening agents.
Your dentist also may require you to undergo whitening if you are planning other cosmetic dental procedures, such as veneers or composite bonding, in order to ensure a better match between the restoration and your natural dentition, or after the removal of braces. Depending on the condition of your teeth and your goals for changing the look of your smile, whitening may not be your best option.
