ABSTRACT: The question of esthetics is a major concern in dentistry today. The color of the teeth is an important factor, since the color harmony is perceived quickly. The single discoloured tooth can be a challenge in obtaining an aesthetic outcome in the anterior region. This case report describes the treatment of a single darkened tooth by combining internal and external bleaching techniques. It is also reported the clinical and radiographic follow-up in which a slight yellowing of the endodontically treated tooth was observed after 2 years. Also described is external bleaching treatment for maintenance of tooth whitening after color recurrence through a 35% hydrogen peroxide whitening session which was sufficient to restore smile harmony. In this clinical case, the whitening treatment provided good aesthetic results.
