Everyone loves beauty. No matter in the modern age with advanced science and technology or in the relatively backward ancient times, people can't stop pursuing beauty. Since ancient times, there have been a series of standards to judge beauty, and some of these standards will change with the influence of the times and people's aesthetic changes, while others will remain unchanged. For example, people in the Tang Dynasty regarded fat as beauty, and the most famous one at that time was Yang Guifei. Her plump figure and her romantic love story with Emperor Xuanzong of the Tang Dynasty are famous works throughout the ages. In contemporary times, thinness is beauty. It is a common phenomenon that many women are determined to lose weight in order to shape their slim figure. This is an example of the transformation of ancient and modern aesthetic standards, and as I said just now, some standards have not changed since ancient times, that is, people's judgment on the beauty of teeth. Since ancient times, people think that having white and neat teeth is a symbol of beauty and an important criterion for judging the value of face. Therefore, from ancient times to the present, especially in contemporary times, people have never given up the pursuit of perfect teeth. Many people even tried many means to pursue perfect teeth and endured severe pain. People's teeth are white and neat when they first grow out. Later, due to some factors, the teeth were not cleaned in time and oral health could not be maintained, which would change the teeth. As we all know, if you want to get a perfect tooth now, you can use medical means such as dental plastic surgery. Compared with ancient times when medical conditions were relatively backward, how to protect teeth, keep oral health and have a beautiful tooth? Although the scientific level of the ancients was relatively backward, it did not affect their pursuit of beauty. The ancients attached great importance to oral hygiene. As early as the pre-Qin period, people praised beauty in this way, that is, "the skin is like coagulated fat, the hands are like soft, and the teeth are like rhinoceros." This shows that people at that time paid so much attention to teeth and mouth that they praised beautiful people with a mouthful of white teeth. Then let's go into the life of the ancients and understand how they protected their teeth. Because if you want to keep your teeth perfect, you must first keep your mouth healthy. In short, you must keep your teeth and mouth clean. In order to do this, the ancients also took great pains in the era of poor resources and backward technology. The first is the simplest cleaning, that is, gargling. Although gargling is simple, it is also the most economical and effective method. Chinese civilization has never been separated from food. China, as a big country of food, has been obsessed with the pursuit of food since ancient times. Therefore, people have to pay attention to the health of teeth, whether from the perspective of pursuing beauty, or for the pursuit of food, or just to meet the basic needs of survival. Teeth are naturally closely related to food, so it is particularly important to rinse your mouth before and after meals. As early as the Eastern Han Dynasty, it was said that food residue would remain on teeth when eating, and it would not be easy to damage teeth if it was cleaned in time before going to bed at night. On the contrary, it will cause great harm to the teeth, and over time it will drift away from a white tooth. Friends who have seen Gongdou Opera are also familiar with such a plot. The emperor's concubine will take a sip of tea after dinner and get up in the morning, but this tea is not swallowed but spit out. Friends who don't know why will think this is a peculiar quirk of the royal family. But in fact, this is a way of gargling, but the royal condition is better, and it will gargle with tea. On the one hand, it can reflect the royal aristocratic status. On the other hand, mellow tea can also remove the odor in the mouth and keep the mouth clean. This shows that the ancients paid attention to gargling. In addition to gargling, the ancients could not eat without objects, which was exquisite and functional. That's a toothpick. Speaking of which, some people will be confused. Isn't toothpick a modern thing? Actually, it is not. Smart human beings have invented toothpicks as early as the distant ancient times. The history of toothpicks in China can be traced back to ancient times, from which we can see that people's attention to teeth has long been formed and has a long history. According to archaeological records, China has formed the habit of picking teeth as early as 2000 years ago. With regard to the spreading history of toothpicks in China, besides archaeological conclusions, there is also a saying that toothpicks are widely used in China because of the influence of Buddhism. Either way, from the source of its spread, it is enough to prove that toothpicks have a long history of use in China, and people's habit of picking their teeth has long been formed. Tooth picking is a simple cleaning method, but it is still far from enough to keep teeth white. Therefore, after toothpicks became more and more popular, someone invented a method to wipe teeth based on toothpicks. This cleaning method can also be seen in Dunhuang murals in the late Tang Dynasty. Specifically, people use Yang Liuzhi dipped in green salt and herbal powder to clean their teeth, so as to achieve better cleaning effect. Moreover, cleaning teeth with toothpicks made of willow wood can not only keep teeth clean, but also keep oral health, because willow wood has the function of reducing swelling and relieving pain, so cleaning teeth can achieve a health care effect and keep oral health. Toothpicks have a long history in China, but with the development of the times, people constantly bring forth the old and bring forth the new, and invented more and more effective tools besides toothpicks, so that people can clean their teeth and protect their mouths in more different ways. It is conceivable how much people value their teeth. Everyone knows the function of willow, so the ancients naturally discovered its mystery, so they processed it properly and made a new tool-toothbrush on the basis of toothpicks. With the appearance of toothbrush, toothpaste also appears gradually. The effect of combining the two is so strong that it is still favored by people. Brushing teeth has become an indispensable part of people's daily life. The origin of toothpaste is also quite related. Toothpaste was recorded as early as the Nanliang period, which can be seen in the "Wuyue Song on the Mountain Peak of Xiyuehua", and the earliest toothpaste formula was recorded: salt, lotus leaf, saponin and so on. Moreover, different from the simple cleaning of teeth in the past, the appearance of toothpaste has added a new effect, that is, the ingredients used to make toothpaste have anti-inflammatory and whitening effects, which makes people open their eyes to it. Of course, it is also from here that people gradually upgrade the role of brushing their teeth to the pursuit of beauty. With the appearance of toothpaste, the manufacturing technology of toothbrush has become more and more sophisticated, and the materials have also developed from the earliest willow leaves to the later ponytails and then to more exotic materials. As we all know, people in Song Dynasty were full of interest, so in Song Dynasty, brushing teeth was no longer just a habit, but gradually became a fashion. There are many records about toothbrushes in Meng Lianglu. At that time, there were many vendors peddling along the street in Lin 'an city, and toothbrushes were indispensable in many commodities. In addition, Lin 'an City has opened many pavements specializing in the production and sale of toothbrushes, which is enough to show that Song people attached importance to oral cleaning and tooth beauty. In short, through the evolution of various dental care methods and tools in ancient times, we can see that people pay more and more attention to oral health and pursue beauty. Of course, the pursuit of health comes before beauty. After all, at first people only realized to clean their teeth in order to keep their teeth healthy and meet their dietary needs. However, with the development of society, people have invented more and more ingenious methods of tooth cleaning care, and more effects have been born. After the basic needs are met, people gradually begin to pay attention to the beauty of teeth, and take having a perfect tooth as the criterion to judge beauty. Health and beauty are always related. The healthier the teeth, the more they can meet the standards of beauty, so they coexist. References:
