What Is It?
Tooth whitening is a procedure that lightens teeth and helps to remove stains and discoloration. Whitening is among the most popular cosmetic dental procedures because it can significantly improve the appearance of your teeth at much less cost and inconvenience than other techniques.
Every day, a thin coating forms on your teeth and it picks up stains. Also, the outer layer of each tooth, called the enamel, contains pores that can hold stains. Whitening is not a one-time solution. It will need to be repeated periodically if you want to maintain the brighter color. See page

How white can I have my teeth?
A change of just two or three shades can make a noticeable difference in almost anyone's smile. The goal should be to achieve your individual optimum whiteness while still looking natural.

Why do my teeth get a darler color?
The most common reasons for yellowing or stained teeth are aging, tobacco, tea and coffee, which can stain the surface of the teeth.
It is also possible to have stains that are inside the tooth. These are called intrinsic stains. For example, intrinsic stains can be caused by exposure to too much fluoride as a child while teeth are developing. Other causes include tetracycline antibiotics taken during the second half of pregnancy or given to children 8 years old or younger when the teeth are still developing.
Tooth whitening is most effective on surface stains caused by age, foods or drinks.

Is it difficult to keep my teeth white?
Over time, exposure to foods, drinks, for example coffee, tea, colas, red wine and tobacco will gradually darken your newly whitened teeth. But there are steps you can take to maintain your pearly white smile. Compared to the time and/or money required to whiten teeth, it takes only a small effort to keep them looking their brightest.
Here are some tips for maintaining your newly whitened teeth:

• Use a whitening toothpaste to remove surface stains and prevent yellowing
• Brush or rinse immediately after consuming stain-causing beverages or foods
• Use a straw to drink beverages that stain, such as coffee, tea, colas and red wine. See page
