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 dental enamel) is inserted on the inside of each tray, giving them their whitening properties.
After they have been used and taken off, they need to be cleaned with a Q-tip or cloth and rinsed. This makes them ready to be used again. After each application, it is advisable to wait at least another day before another session.
The 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.
