Background/Objectives: The presence of postmortem pink teeth is a phenomenon occasionally observed during forensic autopsies. This phenomenon has been typically associated with deaths involving drowning, asphyxiation, trauma, or electrocution. However, the recent literature suggests that it is nonspecific. Despite being recognized in forensic literature for decades, its pathophysiology, prevalence, and forensic relevance remain controversial. The existing evidence is scattered and primarily based on case reports, narrative reviews, or isolated observations. This scoping review aims to systematically map the available scientific evidence on the phenomenon of postmortem pink teeth and its potential role in determining the cause of death within the context of forensic medicine. Methods: This review was conducted following the Joanna Briggs Institute (JBI) methodology for scoping reviews and reported according to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Results: A comprehensive search was carried out across multiple databases to identify studies addressing the occurrence, mechanisms, and forensic interpretation of pink teeth in postmortem examinations. After application of the inclusion and exclusion criteria, the search allowed for the selection of 12 publications (case reports and observational studies). Conclusions: Collected data from the selected studies allowed us to conclude that PTP is a nonspecific taphonomic artifact, lacking diagnostic value in determining the cause of death. Mapping the current evidence on pink teeth contributed to a better understanding of this phenomenon and its lack of forensic significance, promoting more informed decision-making in postmortem assessments.
