Introduction to tooth whitening

Abstract

Few dental treatments have been more successful and conservative in nature than tooth whitening. Therefore, it is noteworthy to mention the efforts of pioneers in our dental profession who continuously attempted to search for the most effective and safest whitening agent. This quest has extended to determine the best whitening technique to meet our patients’ desires and expectations about the aesthetic outcome. Here, a short history of tooth whitening agents developed and employed based on the type of discoloration is summarized, as is our current knowledge on the relative effi cacy and safety of various types of tooth whitening regimens available. The information on proper diagnosis and treatment planning will guide the clinician in establishing a step-by-step protocol for determining the etiology of the discoloration, selecting the best whitening technique, and monitoring tooth color until the desired outcome has been achieved.
