Why do Americans have whiter teeth?

It is generally believed in the west that the teeth of Americans are obviously better than those of other western countries. Even this is the most obvious difference between Americans and other western countries. When talking about American teeth, the BBC once quoted an Irish student as saying, "You can easily tell which Americans are, even if they wear Irish clothes, because they have a unique feature: they all have neat white teeth."

We know that almost all Americans, from Obama to ordinary citizens, have enviable teeth. How did they do it? It turns out that they have mature standards for preventing dental diseases.

Americans care about babies' teeth from the moment they grow their first teeth. Parents will brush the baby's teeth, check whether the teeth are misaligned, and correct them in time after replacing the permanent teeth.

They usually formulate three principles of dental health: brush your teeth twice a day for two minutes each time; Floss every day; Wash your teeth every six months. Flossing is very important because no matter how fine the bristles are, they can't brush the space between two teeth. However, most people in China have no habit of flossing.

Good living habits are the lowest cost and the most effective way to protect teeth. Because dental diseases, like most modern diseases, are caused by lifestyle. If treatment can't change living habits, it will recur. Health ultimately depends on the cultivation of one's living habits.

Europeans maintain their teeth mainly from the perspective of health, but many Americans have raised their teeth to the height of social needs. Americans believe that teeth should be not only healthy, but also beautiful.

The United States is a society where the individual is supreme and pays special attention to individual performance. Americans have been encouraged and trained by social skills and self-confidence since childhood, which makes them look like salesmen who are good at selling themselves. American social culture will cultivate a sense of paying attention to appearance.

Americans believe that good teeth are not only related to health, but also a necessary social condition. 55% of Americans think that smiling is the most important thing in social situations. 73% of Americans believe that no matter how charming a person's smile is, bad teeth will destroy it. Half of Americans go to the dentist twice a year on average.

However, I'm afraid the cultural factors are not that big. There is no significant difference in the frequency of dental care between Europeans and Americans, but Americans can spend more money on their teeth. Of course, this is related to the improvement of their good dental level. No matter which country invents the most advanced and expensive dental technology, it is always widely used in the United States.
