Sooner Or later

 From the pre-Qin to the Han Dynasty, the ancients had high requirements on oral cavity, tooth cleaning, health, disease, etc. For example, in the book of songs, Weifeng, shuoren, it describes that the teeth of a beautiful woman are very white, that is to say, the teeth of a beautiful woman are as white as those of a gourd seed.
In Sui and Tang Dynasties, "brushing teeth" began to appear in China. At that time, the way of brushing teeth was not the same as today's, but "brushing teeth". This method originated from ancient India and is related to Buddhism. According to legend, When Sakyamuni taught under the bodhi tree, the disciples around him had bad breath. So Sakyamuni began to persuade people to pay attention to cleaning their teeth, and teach students how to make toothbrush with branches. Later, with the introduction of Buddhism into China, the method of wiping teeth also spread to China.
In the medical book of Tang Dynasty, the secret essentials of waitai, this method of wiping teeth is recorded in detail: "every time willow branches bite their heads soft, point to take medicine to wipe teeth, fragrant and smooth." It means that one end of the willow branch is softened with teeth, and then dipped with a little powder to brush teeth. This method of brushing teeth is also known as "the method of wiping teeth with willow branches", and the willow branches used are also called "toothwood". Toothwood is the earliest brush tool in China, which can be called "toothbrush" of that era. If you don't have willow branches, you can use other branches instead. If you can't, just wipe your teeth with your fingers. In the 196th grottoes of Dunhuang Grottoes, there is a late Tang mural named "the change of Lao Du's forks and fights", in which you can see the picture of wiping your teeth with your fingers.
By the Song Dynasty, there was an obvious time limit for brushing teeth. In the Taiping Shenghui Fang, it was pointed out that brushing teeth should be done twice sooner or later. It is also recorded that willow branch, Sophora branch, mulberry branch, etc. are boiled with water and used as toothbrush. At the same time, they should dip in ginger juice when brushing their teeth, which is needed every day. This may be the prototype of medicated toothpaste.
When the ancients brush their teeth, they did not dry them with toothbrush, but dipped the toothbrush head with tooth powder, just like the toothpaste used by modern people. This kind of tooth powder has two kinds of paste and powder. Its ingredients include Chinese herbal medicines such as saponin horn, ginger, cohosh, rehmannia, dryland lotus, etc. some salt may be added. The toothpaste of the ancients was natural, herbal and environmental friendly.
Tooth powder originated in the northern and Southern Dynasties, when people began to wipe their teeth with salt and rinse off with water. In Song Dynasty, the texture of tooth powder was improved, including "Qinjiao Sanfang" and "longnaosanfang". In the Hong's collection of prescriptions, there are records of xiangfuzi and ginger dregs mixed with salt to make tooth powder. Others have their own recipes, such as Su Shi's turpentine and tuckahoe, and Shen Kuo's Sophora powder.
In Song Dynasty, "tooth powder shop" appeared, selling tooth powder made of traditional Chinese medicine. Tooth powder has become a social commodity. In Ming Dynasty, seven kinds of Chinese herbal medicine were used to make tooth powder for the Royal dignitaries to protect and clean their teeth.
It was not until the 18th century that Britain began to industrialize the production of tooth powder, which became a commodity in the West. At the beginning of the 20th century, China began to industrialize the production of tooth powder. The earliest products were "Earth" brand and "old train" brand. At that time, the main raw materials of tooth powder were calcium carbonate, talcum powder and magnesium carbonate. Toothpastes are improved and formed on the basis of tooth powder. Compared with tooth powder, more humectants and thickeners are added to the toothpastes, so that they can be stored in the form of paste, which greatly improves the convenience of use. When toothpastes appear, they quickly replace tooth powder.
The difference between toothpastes and toothpastes mainly lies in the form of powder and paste. However, the form of toothpastes greatly reduces the effective ingredients due to the addition of a large number of water and humectants. Especially the whitening effect is reduced. But with the progress of technology, the technology of tooth powder is more mature. After strengthening the oral cleaning, the difference with toothpaste is smaller and smaller.
 
Difference between tooth powder and toothpaste
1. Advantage - tooth powder has great friction on teeth, so it has advantages in removing tartar, plaque and calculus;
2. Ingredients: tooth powder generally does not contain artificial colors. Toothpaste is a chemical process adhesive paste prepared in a single way, containing artificial colors and flavors;
3. Effect: tooth powder is more powerful than toothpaste through brushing and rinsing! Toothpastes mainly remove bacteria, but generally can't remove plaque, tartar and calculus;
4. Formula - tooth powder pays attention to formula and function. However, toothpaste can't add more or complete formula because of adding a lot of water and humectant;
5. Attention - tooth powder pays attention to tooth fixation and tooth maintenance. The toothpaste focuses on oral cleaning with different points.
Therefore, toothpaste can be used to clean the mouth, which is simple and convenient. It is suggested to use tooth powder for teeth fixation and maintenance. With the increasing awareness of health and the cognitive demand of tooth powder for teeth fixation and maintenance, tooth powder return has become a world trend.
