The biggest difference between in-office bleaching and customized at-home bleaching trays is time and cost. They are both prescribed by a dentist.
- Unlike the trays you find in over-the-counter kits, professional dental bleaching trays for at-home use are made to fit your individual teeth, which will maximize comfort and lessen sensitivity and irritation because they fit better and the peroxide solution used to bleach the teeth goes where it’s supposed to go. You can continue to use to reach your ideal shade of white. Trays must be worn over the course of one to two weeks, depending on stain level.
