Whitening procedures have effectively restored the smile of people with stained, dull, or discolored teeth.
The darker tissue of your teeth, the dentin, can become exposed as the outer layer of enamel is worn away by the effects of aging or things like caffeine and tobacco. Food particles are naturally attracted to a tooth's enamel by a certain protein. Products like coffee and tea, berries and soy sauce are notorious for staining teeth. Over time, teeth actually become more absorbent and vulnerable to staining from food and other substances.
The extrinsic factors can be removed by professional cleaning, polishing and Air flow plus while the intrinsic factors can be only solved by tooth bleaching or tooth whitening.
More and more people today are choosing tooth-whitening procedures to reverse the effects of aging and abuse from food and tobacco stains. Some commercially available "whitening toothpastes" can be somewhat effective at removing stains and making teeth a few shades brighter. However, many of these products have abrasive substances that can actually wear away your tooth's enamel.
