When considering retail home teeth whitening systems, knowing the difference between whitening products will help you select the right one to meet your whitening needs.
Many products (such as some toothbrushes and toothpastes) whiten by polishing away surface stain. These products do not contain bleaching agents and do not remove stains below the tooth surface.
Home teeth whitening systems, on the other hand, contain a whitening agent - hydrogen peroxide - that chemically reacts with stains below the enamel as well as with surface stains. Such systems typically provide faster and more dramatic whitening results compared to products that whiten by removing surface stain. Home whitening systems like Crest Whitestrips require that you wear strips for a certain amount of time each day. They are generally gentler and certainly less expensive than having your teeth whitened in a dental office.
Home tooth-whitening systems whiten by removing stains on the teeth's surface as well as stains below the enamel, while most of whitening toothpaste and toothbrushes only remove surface stains.
