When you want whiter teeth, your dentist may suggest you be fitted for at-home bleaching trays, especially after an in-office bleaching treatment, which are essentially custom-made trays prepared precisely for your smile.
Place the bleaching gel into the trays every few nights (or as instructed by your dentist), and place them over your teeth while you sleep to continue the whitening process.
Unlike over-the-counter whitening strips, trays allow every part of the tooth to be saturated with the bleaching gel. Just be sure not to over-bleach, as it can damage teeth and gums.
