What is the main indication for tooth whitening procedures?

The main indication for tooth whitening procedures is to improve the aesthetic appearance of discolored teeth. Many individuals seek whitening treatments to enhance their smile, boost their confidence, and create a more youthful appearance. Discoloration can occur due to various factors such as aging, dietary choices, tobacco use, or certain medications. By utilizing whitening techniques, practitioners can effectively lighten the shade of the teeth, providing a more appealing look and addressing the concerns of patients who may feel self-conscious about the color of their teeth.

Other options, like treating cavities, strengthening tooth enamel, or preventing gum disease, focus on dental health rather than aesthetic improvements. While maintaining oral health is crucial, tooth whitening specifically targets cosmetic enhancement, which makes option B the correct choice.
