People typically have a tooth whitened to improve their appearance. Teeth that are all of the same bright color are associated with beauty and a healthier lifestyle. When people have a brighter smile, they tend to smile more often and are less self-conscious.
In addition, a whiter smile tends to minimize the appearance of facial wrinkles, giving way to a more youthful and energetic appearance. Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.
Research indicates that tooth bleaching is completely effective in more than 78% of people. In cases of serious tooth discoloration, bleaching may not be the best choice. Veneers or crowns may be the superior choice.
