The term global burden of oral diseases refers to the overall impact on the occurrence of oral diseases within the global population. This includes various aspects such as the impact and occurrence of dental problems, the extent of illness and disability that arises from oral diseases, death that may arise from oral or mouth cancers and the overall impact of oral health on general health. Public health professionals analyse current and evolving trends in oral diseases, including the frequency of these diseases and determine preventive strategies. Based on this analysis, they can develop effective national policies to improve and enhance the oral health of the population.
