The 17 sustainable development goals (SDGs) were established by the United Nations Agenda 2030 plan of action to achieve peace, prosperity, and well-being for all by 2030. SDG 3 aims to ensure healthy lives and promote well-being for all at all ages. However, oral health is not specifically mentioned and targeted in SDG 3. Numerous studies have demonstrated a connection between oral health and general health. Oral disease and the common non-communicable diseases have the co-existing modifying risk factors. In addition, oral health is associated with social, economic, cultural, and environmental problems. By the implementation of oral health care, oral health promotion, and universal health coverage, these could not only be good for oral health but also benefit for general health and well-being. Taken together, oral health is the first step to SDG 3.
