ABSTRACT
Oral diseases are a global public health issue. They are among the most prevalent diseases in the world and have a considerable effect on people’s quality of life. Oral diseases also create a significant economic burden for society. Of all oral diseases, the most common are dental caries, periodontal disease, and cancers of the oral cavity, including the lips. Worldwide, oral diseases affect 3.9 billion people and untreated caries in adults was found to be the most prevalent condition in the Global Burden of Disease Study. They also share common risk factors with other non-communicable diseases (NCDs), which have increased sharply in low- and middle-income countries (LMIC). Poor oral health can indicate low socio-economic status, poverty, and lack of access to services, with oral health inequality increasing. This chapter will focus on health inequalities and the burden of oral disease globally, also linking it to the process of the globalisation of health and lifestyle.
