ABSTRACT:
A dental composition and method for bleaching vital and non-vital teeth, comprising a preselected, concentrated, aqueous solution of hydrogen peroxide and a nonaqueous component mixed to form an aqueous gel or paste, with the nonaqueous component including an inert silica gelling agent, an accelerator, a plasticizer and thickening agent, and means for establishing a substantially fixed time period for treating the teeth in response to the application of optical energy. A redox color indicator is used to transform from one color to another over the fixed time period to provide a visual indication that the treatment is completed, as well as an indication that the peroxide solution was active.
