Cosmetic dentistry is usually used to refer to any dental work that recovers the arrival (though not necessarily the functionality) of teeth, gums and/or bite. It chiefly focuses on development in dental aesthetics in color, location, shape, size, arrangement and overall smile arrival. Many dentists refer to themselves as "cosmetic dentists" regardless of their exact education, field, exercise, and experience in this field. This has been careful unprincipled with a main objective of marketing to patients. The American Dental Association does not know cosmetic dentistry as a formal specialty area of dentistry. However, there are still dentists that indorse themselves as cosmetic dentists.
