The answer to this question varies from person to person, depending on age, skin tone, eye color and personal preference. But here's a good rule of thumb; the whiteness of your eyes should match the color of your teeth. Additionally, you might consider your age and gender. Teeth darken naturally as we age, so selecting a shade that's too white may seem unnatural for older patients. Women, too, have more leeway when selecting shades than do men. What works on a woman may again look unnatural on a man. Your dentist is the best guide for shade selection - he or she will consider your preferences and help you achieve a sensible and attractive coloration.
