Whitening paradigms 1 year later: introduction of a novel professional tooth-bleaching system.

The recent development of a novel "trayless" delivery system for vital bleaching shifted treatment paradigms and spurred surprising growth in tooth whitening. New research on a professional-only system (Crest Professional Whitestrips) further expands treatment options. This easy-to-use hydrogen peroxide strip system represents an effective and safe approach for increased whitening. Clinical applications are extensive, ranging from general, point-of-entry whitening to chronic use in difficult case types.
