Custom whitening trays are clear and usually made of plastic that comfortably adjusts when inserted. A small dollop of gel (consisting of a hydrogen peroxide solution that actively whitens the enamel of teeth) is inserted in each tray, giving them their whitening properties.
After they have been used and removed, they need to be cleaned with a cotton swab or cloth and rinsed. This makes them ready to be used again. After each application, it is suggested to wait at least another day before using again.
These whitening trays can be used several times to obtain the desired results. Our dentist will let you know how many times you need to use them.
