Teeth are one of the important organs of human beings. They help us chew food. We use teeth every day. In modern times, we use many tools to clean teeth. As the saying goes Toothache is not a disease, it hurts terribly. Teeth are really very important to us. Ancient people cleaned their teeth
In fact, people in ancient times paid great attention to whitening their teeth. "The Book of Songs Wei Feng Shuo Ren" described the teeth of beautiful women as "teeth like gourd rhinoceros", which means that the teeth should be like gourd seeds. As neat and white as a child. On the contrary, uneven teeth are considered discordant, uneven bites are called cavities, uneven alignments are called cavities, and uneven teeth are called caries, all of which are regarded as pathological. It can be seen that people in ancient times attached great importance to dental health. The specific methods of cleaning teeth of the ancients
In fact, the ancients were smarter than we thought, and they also had many methods of cleaning their teeth. It is recorded in the "Book of Rites" that the ancients would rinse their mouths with salt water when they got up in the morning. There is an allusion in "Book of Jin·Biography of Sun Chu" called "washing stones and pillows". Sun Chu wanted to live in seclusion when he was young, and said to Wang Ji: "Zhenliu" means washing ears with stream water, so "washing stones" means "to sharpen his teeth." Rinse your mouth with gritty water to clean your teeth. In addition to water, there is also a cloth specially used to wipe teeth, which also plays a role in cleaning teeth. In ancient times, ordinary people also had a stupid way to clean their teeth with their fingers. Not only that, in the late Tang Dynasty, our people also invented toothpicks and toothpicks. , which is the earliest toothbrush. Starting from the Tang Dynasty, people used willow branches to make brushes and dipped them in liquid to clean their teeth. Wang Tao, a doctor of the Tang Dynasty, described in "Waitai Mi Yao" that Cimicifuga, Angelica dahurica, agarwood, etc. were used as medicine, crushed into powder, flattened willow branches, and some medicine was applied to scrub the teeth. This was the prototype of early toothbrushes and toothpastes. In the Yuan Dynasty, most people used willow branches as toothbrushes and brushed their teeth with tooth-wiping powder made from Chinese herbal medicine. In "Jingsi Ji", Guo Jue said, "Short hairpins are cut into light tortoise shells, and ice silk locks are used to lock silver bristles." This shows that in the Yuan Dynasty, toothbrushes were quite popular, and the handles of toothbrushes at that time were not very long. The shape is like a tortoise shell, and the bristles used in the bristles have been refined, giving it the prototype of a modern toothbrush.
So the ancients were very wise. There are many ways to clean your teeth.
