俗话说:“十人九龋”,“牙疼不是病,疼起来真要命”。世界上,几乎每一个人都有过牙痛的体会,遭受牙痛之苦者,更是比比皆是。然而,爱护牙齿,预防牙病,这一问题尚未引起人们足够的重视。2002年2月底,全国牙病调查统计表明,我国拥有龋齿总数为20多亿个,而且这些龋齿90％没有得到治疗。与此同时,牙周疾病已成为危害我国口腔健康的首要问题。所以希望大家能够珍爱自己的牙齿,维护口腔健康,因为,健康才是您最宝贵的财富！ As the saying goes: “Ten people nine caries,” “toothache is not a disease, it hurts really terrible.” Almost everyone in the world has had a toothache experience, suffering from toothache is more abound. However, caring for teeth and preventing dental problems have not given enough attention to people. The end of February 2002, the national dental survey statistics show that China has a total number of caries of more than 2 billion, and 90% of these dental caries have not been treated. At the same time, periodontal disease has become the primary problem that endangers oral health in our country. So I hope everyone can cherish their own teeth and maintain oral health, because health is your most valuable asset!
