Are Your Bright Teeth the Right White?

Are Your Bright Teeth the Right White?

Studies have shown that bright teeth are as important a feature in an attractive smile as tooth shape and alignment. An attractive smile and bright teeth can promote self-esteem and self-confidence in your personal and professional life. In a 2007 study, researchers at Loyola Marymount University in Los Angeles, California, found that human resources professionals rated research subjects with bright teeth and an attractive smile more favorably in job interviews, and gave them longer interviews and higher salary offers.

Get the Right Bright Teeth

But how do you know whether your bright teeth are bright enough? What defines bright teeth is subjective, and one rule of thumb for natural-looking bright teeth is that the white of your teeth should be similar to the white of your eyes. (3) But there is some scientific guidance for assessing bright teeth. A method developed by the Commission International de l’Eclairage to measure bright teeth evaluates the change in tooth color for bright teeth in three ways: a decrease in yellowness, a decrease in redness, and an increase in lightness compared with the color of the teeth before whitening.

Your Options for Bright Teeth

Manufacturers of whitening products are responsible for labeling products properly, so you know the ingredients and whitening intensity of different products for bright teeth. You can choose from whitening strips, whitening toothpaste, whitening rinse, or a combination of products to find the regimen that yields the bright teeth that are right for you. (5)
