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.
One type of stain—caused by traumatic injuries, medications and fluorosis—actually begins inside
the tooth; brushing and flossing don’t help. Another type of stain—one that can be more easily
attacked by brushing, flossing and rinsing—is caused by external factors such as foods.
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.
Whitening agents actually change the color of your teeth, but only are effective on certain
types of stains. For example, bleaching agents have a difficult time removing brownish or
grayish stains. These products also are not as effective on pitted or badly discolored teeth, or
on restorations such as crowns, bridges, bonding and tooth-colored fillings (porcelain veneers
or dental bonding may be more appropriate in this case).
Professional whitening performed by our office is considered to be the most effective and safest
method; done properly, tooth whitening can last as long as five years. Over-the-counter
whitening systems are somewhat effective as long as they are monitored and directions followed
closely.
