During the series of promotional activities for National Tooth Love Day, oral health issues have once again drawn public attention. Data shows that the periodontal health rate of adults in our country is only 9.1%, and the prevalence of dental caries among children continues to rise. The situation of oral health is not optimistic. So, why do we need to protect dental health? Behind this issue lies an important answer concerning the health of the entire population. Dental health not only affects chewing function, but is also closely related to overall health. Experts from the Chinese Stomatological Association emphasized at the event that the bacteria and their metabolic products produced by periodontitis can enter the bloodstream, causing or exacerbating systemic diseases such as cardiovascular and cerebrovascular diseases and diabetes. In addition, the pain and chewing difficulties caused by dental caries can affect nutrient intake, especially having a negative impact on children's growth and development. The World Health Organization has long listed oral health as one of the ten standards of human health.

It is worth noting that there are also significant age differences in oral health problems. The adolescent group has a high incidence of dental caries due to insufficient dietary habits and awareness of oral hygiene. Middle-aged and elderly people are troubled by periodontal disease, with frequent occurrences of loose and fallen teeth. In response to this situation, many medical institutions in various places have launched oral health screening activities in communities and schools. Through free examinations and popular science education, they aim to enhance public health awareness.

Protecting dental health is not only a guarantee of one's own quality of life, but also an investment in overall health. With the continuous advancement of the "Healthy China 2030" plan, oral health has been incorporated into the national health management system. In the future, through policy support, popular science publicity and the enhancement of personal health awareness, it is expected that the oral health conditions of Chinese residents will be gradually improved.
