The Best Way to Whiten Your Teeth
How to get a mouthful of natural-looking pearly whites.
To prevent future spells of supernova smile, complete a cycle of at-home bleaching only once a year, and monitor the color of your teeth as you go. Stop the process when your teeth reach a natural shade of white.
Not sure what the right natural white is for you? Before you bleach, ask your dentist to show you a shade guide marked with the starting color of your teeth and an appropriate ending shade, so you can keep track precisely.
