ABSTRACT:
An improved method for bleaching teeth using a pre-formed stock tray of a thermoplastic material with a low-heat melt-index, and a peroxide gel. The tray is custom fitted at home by the wearer, instead of having to go to a dentist. It is placed in boiling water a few seconds to soften, and is adapted snugly over the teeth in one arch. An oxidizing gel of an over-the-counter oral antiseptic is placed inside the tray, which in turn is placed over the teeth. After a period of time the gel is replenished again. This is done several times throughout the day, and continued for 2-3 weeks. The end result being whiter teeth and a new smile.
