An applicator for applying a bleaching agent in the form of a bleaching gel composition to the teeth of a user for purposes of whitening or brightening the teeth. The applicator is in the form of an arch or so-called “tray”. The applicator is formed of a flexible and bendable plastic, such as a vinyl plastic, so as to be capable of being partially molded to conform to the teeth configuration of a user. A spacer or insert is located in the tray and contacts the front surfaces of the teeth when inserted on the teeth. The spacer is spaced slightly rearwardly from the front surface of the arch-shaped tray to create a reservoir when the tray is effectively molded to conform to the configuration of the user\s teeth. The user of the applicator inserts the applicator into his or her mouth after heating the application and the insert and which causes the plastic to become somewhat moldable. In the heated stage, the applicator, with the insert or spacer located therein, will essentially mold and conform to the shape and contour of the user\s teeth. When the applicator is removed from the user\s mouth and when the insert is removed from the tray, a reservoir will exist in the frontal portion of the tray, so as to receive and retentively hold the bleaching gel composition against the front surface of the teeth.

A bleaching tray for applying a bleaching composition to the teeth of a user, said tray comprising: a) an arch-shaped outer wall adapted to extend around the exterior surface of the teeth of a user in the arch of the user; b) an arch-shaped inner wall connected to said outer wall and adapted to extend around and substantially engage the interior surface of the teeth in the arch of the user; and c) said inner and outer walls being sized and shaped to form a recess which receives the arch of the user when in use, the interior surface of said outer wall being slightly spaced from the exterior surface of the teeth in the frontal portion of the arch; and d) an insert removably located in said recess and which has an upstanding insert wall spaced apart from an inner surface of the outer wall by a small distance to define a bleaching agent receiving reservoir when removed, said insert being present in said recess when the tray is fitted to a user and removed thereafter so that when used on a user with a bleaching agent the interior surface of the outer wall is spaced from the exterior surface of the teeth in the frontal portion of the arch, such that the bleaching agent receiving reservoir around the front of the teeth allows the bleaching agent introduced into the reservoir to be in contact with the teeth.
