Oral health Impact

Poor oral health causes millions of people to suffer from devastating pain and increases the out-of-pocket financial burden for society. Oral diseases can affect an individual’s effectiveness in school and work settings and can cause social and personal problems. The psychosocial impact of many oral diseases significantly reduces the quality of life.

While the global burden of untreated dental caries in primary and permanent teeth has remained relatively unchanged over the past 30 years, the overall burden of oral health conditions on services is likely to keep increasing because of population growth and ageing.

Oral diseases disproportionally affect the poor and socially-disadvantaged members of society. There is a very strong and consistent association between socioeconomic status (income, occupation and educational level) and the prevalence and severity of oral diseases. This association remains across the life course, from early childhood to older age, and across populations in high-, middle- and low-income countries.

Oral health-care treatment is costly, averaging 20% of out-of-pocket health expenditure in most high-income countries. The demand for oral health care is beyond the capacity of health-care systems in most low- and middle-income countries, and many people in some high-income countries are unable to afford proper care.

 

Oral health

Oral health is a key indicator of overall health, well-being and quality of life. It encompasses a range of diseases and conditions that include dental caries, Periodontal disease, Tooth loss, Oral cancer, Oral manifestations of HIV infection, Oro-dental trauma, Noma and birth defects such as cleft lip and palate. The Global Burden of Disease Study 2017 estimated that oral diseases affect 3.5 billion people worldwide, with untreated dental caries being among the most prevalent noncommunicable diseases. According to the International Agency for Research on Cancer, the incidence of oral cancer was within the top three of all cancers in some Asian-Pacific countries in 2018.

Most oral diseases and conditions share modifiable risk factors with the leading NCDs (cardiovascular diseases, cancer, chronic respiratory diseases and diabetes). These risk factors include tobacco use, alcohol consumption and unhealthy diets high in free sugars, all of which are increasing at the global level. There is a proven relationship between oral and general health. It is reported, for example, that diabetes mellitus is linked with the development and progression of periodontitis. Moreover, there is a causal link between high sugars consumption and diabetes, obesity and dental caries
