This issue is important because it affects not only the aesthetics of the patient, but also his/her self-esteem and generates psychosocial consequences. Internal dental bleaching is an alternative in solving this problem, a method that has already proved effective and has several studies in the literature that support its effectiveness.

Material and methods: The search for the present review was performed in the Pubmed database, with an interval of 6 years, 2017 to 2022. Result: The research brought as a result reports of cases that evidenced several etiological factors such as trauma, bacterial infection, fluorosis, eating habits, presence of blood in the pulp chamber, the most common being endodontic treatments because of endodontic pastes containing antibiotics as a reason for the procedure' need. As for the bleaching agent used, each author uses specific bleaching agents, but which had in common the oxidation process as a mechanism of action to perform tooth bleaching. Conclusion: The present work allowed us to conclude that internal dental bleaching is a noninvasive treatment option, effective most often in reversing the color of a tooth in the condition of absence of pulp vitality and with a good level of safety, however, further studies are necessary in the improvement of techniques and substances for the optimization of the procedure.
