Although my specialty is not pediatric dentistry, but every day in the clinic will encounter many parents bring their children to check such as face swollen, swollen teeth bleeding and other small patients, every time I see a mouth of “small rotten teeth”, and is angry and helpless, said that the level of oral health care in a country is a reflection of the national economic level, but Our economic level has developed, some parents still can not keep up with this health care awareness, it is very distressing. Hospitals sometimes see that even some children with blood disorders do not do the initial treatment, because the infection missed the opportunity to save lives such as bone marrow transplantation, or would have been a very small problem, and eventually need to pay a big price to restore.
