An exam will help us to determine if you are a candidate for custom whitening.   Impressions will be taken and use  to make models of your teeth. These models are used to make a personalized whitening tray that fits over your teeth. The trays are filled with the whitening gel at home then you place the trays on your teeth, keeping it in place for approximately 1 hour everyday. You will see results in about 2 to 3 weeks. Since peroxide is the main ingredient it will not cause damage to the enamel or cause sensitivity and is actually very good for your gums.
