Introduction: The increasing demand for a better look and a whiter smile has made tooth whitening a popular procedure. Even though tooth Bleaching is considered a conservative and non-invasive treatment modality, it has some adverse effects, like tooth sensitivity. Carbamide peroxide is widely used as a bleaching agent in external bleaching techniques due to its efficacy and safety. The objective of this study is to evaluate the impact of different methods of sensitivity control regarding external tooth bleaching using carbamide peroxide. Materials and Methods: An electronic search was performed using PubMed/Medline®, Cochrane® and Web of Science® with a specific search strategy combining controlled terms and natural language. Relevant studies were selected and evaluated after reading the full text. Results: Through a search strategy, 603 articles were identified. Duplicate articles have been removed. By reading the titles and abstract of 274 articles, 56 articles were selected to read in full in order to assess eligibility. Of these, 33 articles were excluded for not meeting the other inclusion criteria. Twenty-three articles were included in the study. Conclusion: The studies included in this review resorted to evaluating different methodologies used to control tooth sensitivity resulting from external Bleaching using carbamide peroxide. Considering the results found in this study, tooth sensitivity resulting from tooth Bleaching can be considered a difficult problem to avoid, however, its intensity can be reduced.
