Periodontal disease is common around the world, with the World Health Organization classifying it as a major public health problem due to its high prevalence and links to systemic chronic conditions, such as cardiovascular diseases, diabetes and respiratory illnesses. In China, the burden is particularly acute. A combination of poor oral hygiene, high tobacco use, issues with nutrition and limited access to preventive dental care, means that gum disease strikes early and frequently. Among adults aged 25 to 44 years old, around 87% have bleeding gums, and 97% had calculus buildup - both early signs of gum disease.
