This procedure is used to lighten a darkly discolored tooth. There are two very different types of bleaching, internal and external:
INTERNAL : Non-vital (Internal) bleaching is performed in teeth that have had root canal therapy. A chemical oxidizing agent is placed within the coronal portion of a tooth to remove tooth discoloration. It may be performed at the dentist's office in one or more appointments, depending upon the discoloration of the tooth. When bleach crystals are place inside the tooth and after then removed after a period of time, the procedure is known as "chair side bleach." An endodontist commonly performs these procedures.

EXTERNAL : Vital (External) bleaching is a similar procedure performed by a general dentist on the outside of a tooth or teeth with vital pulps. Teeth that have not had root canal therapy. There are different methods for this procedure, such as lasers, or chemical agents (30% hydrogen peroxide and urea peroxide). The procedure often involves taking an impression of your teeth and the fabrication of a tray that will hold the bleaching agent. The patient wears this tray several hours each day or at night while sleeping. Other methods do not involve trays, but rather bleaching strips.
