Custom whitening trays are clear trays usually made of a clear plastic that comfortably adjust to your teeth when inserted. A small dollop of gel is applied in each tray. The gel consists of a hydrogen peroxide solution that actively whitens the enamel of your teeth.
After the trays are used and removed, they need to be cleaned with a Q-tip or cloth and rinsed. This makes them ready for use again. It is not suggested that they be used for at least a full day after each application.
These whitening trays can be used multiple times to obtain the desired results. Our dentist can further advise you on how many times they should be used in each case.
