Question
What is home bleaching?

Answer
Home bleaching involves wearing a very thin, transparent plastic tray molded to your teeth, which is used to hold a bleaching agent in contact with the tooth surface. It is normally worn for approximately ten days.
The active agent in the bleach is usually carbamide peroxide. This is a chemical which quickly breaks down to urea and 7% hydrogen peroxide. It is the hydrogen peroxide which lightens the teeth.
