The single discoloured tooth poses an aesthetic dilemma. While several treatment approaches are available, bleaching offers a minimally invasive, aesthetic treatment modality. Predictability and success with bleaching stems from correct diagnosis, didactic treatment planning and the utilisation of appropriate techniques. This article aims to discuss the aetiologies of a single discoloured tooth and, through evaluation of the literature and discussion of clinical cases, explore the theory, safety and bleaching techniques available.
