The specialized field of diving or underwater dentistry addresses the unique oral health challenges faced by divers in the underwater realm. It stands distinct from traditional dentistry due to the impact of underwater conditions, notably pressure on oral health. Professionals in this domain, including dentists, oral surgeons, and researchers, collaborate to address the specific oral health concerns of divers. Historical records and documented cases reveal the evolution of diving dentistry, showcasing oral health issues like barodontalgia, temporomandibular joint disorders (TMDs), and dental barotrauma experienced by divers in deep-sea environments. These experiences underscore the urgent need for specialized care due to the diverse oral health problems arising from extreme underwater conditions. The oral health effects in deep-sea environments stem from factors such as pressure differentials, gas expansion, and alterations in air supply, resulting in tooth and tissue injuries. Understanding these factors is crucial in devising preventive measures and treatments tailored for divers. Strategies for managing these issues involve specialized dental treatments, preventive care, and education for both divers and dental professionals. Dental clinics equipped with specialized tools and expertise play a pivotal role in recognizing and addressing these unique cases. The significance of diving dentistry lies in the distinctive challenges it poses, requiring continual advancements and specialized care. As the field progresses, future prospects suggest promising developments in research, technology, and methodologies aimed at enhancing the oral health of divers. This review offers a comprehensive exploration of the critical role of diving dentistry, highlighting the need for ongoing development and focused attention on the oral well-being of those exploring the underwater world
