The pandemic of COVID-19 in early 2020 is a big challenge to the mechanism of major epidemic prevention and control, the national public health management system, as well as medical and health resources in China. Going through the COVID-19 crisis, we should fully understand the problems and vulnerabilities of the current public health system in China, and it is imperative to deepen and strengthen the public health system which should be throughout whole life cycle and whole process. Oral cavity is the first portal of human body, while illness finds its way in by the mouth. Oral health is highly related to general health and quality of life. The outbreak has drawn the public's attention to the public health system. The establishment and improvement of the oral public health system with the concept of "public health with Chinese characteristics" should also attract people's attentions and thoughts. Furthermore it is urgent to recognize the importance of oral public health.
2020年初突发的新型冠状病毒肺炎（COVID-19）疫情是对我国重大疫情防控体制机制、国家公共卫生管理体系以及医疗卫生资源的一次大考验，通过新冠疫情危机我们需要充分认识当前我国公共卫生体系出现的问题和短板，深化和完善全周期、全过程的公共卫生管理体系势在必行。口腔是人体的第一门户，口腔健康关乎全身健康和生命质量。这次COVID-19疫情引发了社会对公共卫生体系的关注，建立和完善中国特色大健康理念的口腔公共卫生体系应引起大家的关注与思考，对口腔公共卫生重要性的再认识迫在眉睫。.
