My feeling is that Americans pay more attention to dental and oral health and have a more correct understanding. Any family with enough money and culture will pay attention to their teeth. Bad teeth can basically be reflected in the fact that your family has no money or education, so you don't pay attention to oral health or don't have the money to pay attention to oral health. None of the lively, popular, and eye-catching college students on American campuses have crooked teeth. As for teeth whitening, more fashionable children will whiten their teeth. Normal teeth are actually not that white.

A more correct understanding of oral health is that if your gums bleed or become inflamed, my parents will think that I am angry. The actual situation is bacterial infection. Another example, when I was planning to remove all my wisdom teeth, my parents felt that tooth extraction would be "hurtful" and that the teeth would become loose after extraction. However, the fact is, I did not have any of these problems after extraction, and it also eliminated the impact of wisdom teeth on me. Wear and tear of the oral walls.
