From pre-Qin dynasty to Han dynasty, the ancients had high requirements for oral cavity, tooth cleaning, health and disease. ? For example, in The Book of Songs? Feng Wei? In Shuo Ren, the beauty's teeth are described as? White teeth like rhinoceros? This means that a beautiful woman's teeth are as white as gourd seeds. . In order to protect their teeth, in addition to gargling after meals, they also use things to remove food left on their teeth.
Wei, Jin, Southern and Northern Dynasties? Toothpick? This word appeared in the historical records of the Western Jin Dynasty. Yun wrote to his brother Lu Ji? One day, I went to Cao Gong's utensils, and I had a sign to pick my teeth. Now I send one to my brother. . This shows that toothpicks have appeared at this time, but toothpicks at that time were still rare.
In the Song Dynasty, there was a clear time limit for brushing teeth. In Taiping Sheng Hui Square, it was pointed out that you should brush your teeth twice every morning and evening. The usage is also recorded: willow, litchi, mulberry and other water are used for cooking. As a toothbrush, you also need to brush your teeth every day. This may be the embryonic form of medicine toothpaste. In fact, toothbrushes with bristles appeared in the Song Dynasty. In the Song Dynasty's "Health Course", there is such a record:? Is brushing your teeth a ponytail? .
Nowadays, there are all kinds of toothbrushes, electric and nano-bamboo charcoal, which are very convenient and easy to use, so we should protect our teeth and brush our teeth every day.
