A dental bleaching composition having enhanced effectiveness and reduced sensitivity, its method of use, and a kit containing the ingredients for making the composition. The dental bleaching composition comprises a bleaching agent, an inert gelling agent, a pH modifying agent, a discrete inert particulate laser enhancing material, and optionally a transparency modifying agent in the form of a gel with a pH of about 9.5 to 11. The dental bleaching composition is placed on the teeth to be bleached, exposed to laser light for a desired period of time, and removed. The process is then repeated for one or more cycles until the desired degree of bleaching is achieved. Neutral sodium fluoride is then applied to the bleached teeth for at least 10 minutes to reduce or eliminate post-bleaching sensitivity.
