Introduction: Dental injuries during anesthesia, especially when advanced airway management is required, represent a legal problem. Factors such as poor dental condition and excessive pressure during intubation contribute to dental damage. The maxillary central incisors are commonly affected. Objective: The objective of this review is to know the incidence of dental injuries in adults undergoing anesthesia that requires airway management. Materials and Methods: The search was performed in MEDLINE (through Pubmed), ClinicalTrials.gov, Scopus, LILACS (through the Virtual Health Library Regional Portal), and SciELO for all available literature on the subject up to December 2022. Inclusion criteria involved articles that studied patients aged 18 years or older who underwent general anesthesia requiring airway management with tracheal intubation or insertion of a laryngeal mask airway. Results: Of all the articles, nine report dental injury associated with the type of airway management. Only one article does not have dental injury. Discussion: This study addresses dental injuries related to tracheal intubation during general anesthesia. Although techniques are used to prevent them, these injuries still occur. Laryngoscopy, especially with support on the upper central incisors, can cause damage to the teeth. Conclusions: It is important that the anesthesiologist is aware of dental trauma and that orotracheal intubation or the placement of the laryngeal mask airway is performed systematically and rigorously, always considering the patient’s dentition to choose the best approach in each specific situation.
