Dental bleaching compositions that include perborate bleaching agents, such as sodium perborate monohydrate. The bleaching agent is dispersed within a sticky and viscous carrier such as a mixture of propylene glycol and silica fume. Anhydrous propylene glycol and/or anhydrous glycerin are especially useful in order to maintain the desired degree of hydration of the perborate being used. Flavorants may be added to enhance the taste of the dental compositions, since they will be used within a person's mouth. For best results, a flexible, thin-walled, comfortable-fitting, custom dental tray is used with the dental bleaching compositions. The dental compositions are sufficiently sticky and viscous so as to adhere and retain a dental tray against a person's teeth which is designed so as to not exert significant mechanical pressure onto the person's teeth.

1. A stable, one-part dental bleaching composition comprising:at least one perborate dental bleaching agent included in an amount in a range from about 1% to about 50% by weight of the dental bleaching composition; at least one liquid polyol; and a quantity of at least one finely divided particulate gelling agent which, when mixed with the liquid polyol, yields a sticky and viscous dental composition.
