Why doesn't China pay attention to dental health?

I think there are several possibilities. First, there is a lack of knowledge about dental health. Second, parents did not pay attention to their children's dental health when they were young. As a result, there are problems when the teeth grow up. Thirdly, the technical level of stomatological medical college in China is still very lacking and needs to be improved. Point: China people don't even know their own way of brushing their teeth. Dental education should be reflected in the school curriculum, so that we can pay attention to dental health from an early age.
