Your dentist will take impressions of your teeth that will allow for custom trays to be made for your bleaching procedure. The gel is placed in these thin comfortable trays and fitted over your teeth. As you whiten your teeth, carbamide peroxide is broken down and oxygen enters the enamel and dentin. This bleaches out the discolored areas. The structure of the tooth is not changed. The color of the tooth is simply made lighter.

The duration of your results depends largely upon you. The results may be permanent. Practice good oral hygiene and brush normally, especially after consuming staining foods or beverages and your results could last for years. If you use staining substances like coffee, tobacco, and red wine you may want periodic touch-ups for one or two days every couple of years.
