Toothpaste is a common cleaning product in daily life with a long history. With the continuous development of science and technology and the continuous improvement and perfection of technology and equipment, various types of toothpaste have come out one after another, and the quality and grade of products have been continuously improved. Now, the variety of toothpaste has developed from a single clean toothpaste to a multifunctional toothpaste with complete varieties, diverse functions and hundreds of brands, which meets the needs of different consumption levels.

The origin of toothpaste The use of toothpaste can be traced back to 2000-2500 years ago. The early works of Greeks, Romans, Hebrews and Buddhists all recorded the use of dentifrices. Early dentifrices were mainly chalk, animal bone powder, pumice and even verdigris. Until the19th century, bovine bone meal and squid bone meal were also used to make tooth powder. Brushing your teeth with salt and gargling with salt still exist today.
/kloc-in the 0/8th century, Britain first began to produce tooth powder industrially, and then tooth powder became a commodity. 1840, the French invented the metal hose, which provided suitable packaging for some daily necessities, thus triggering the reform of some commodity forms. 1893, a Viennese Seger invented toothpaste and put it in a hose. Since then, toothpaste has developed in large quantities and gradually replaced tooth powder.
Toothpaste is improved on the basis of tooth powder. Early tooth powder mainly used calcium carbonate as friction agent and soap as surfactant. Since the 1940s, due to the rapid development of science and technology, the toothpaste industry has also been greatly improved. On the one hand, the development and application of new friction agents, wetting agents, thickeners and surfactants have continuously upgraded the quality of toothpaste products; On the other hand, toothpaste has also developed from ordinary tooth cleaning function to adding drugs to become oral hygiene products for preventing and treating dental diseases, among which fluoride toothpaste is the most prominent one, which greatly reduces the incidence of dental caries. From 65438 to 0945, stannous fluoride was added to toothpaste with calcium pyrophosphate as friction agent and tin pyrophosphate as stabilizer in the United States, and the world's first fluoride toothpaste was developed.

Harm of Inferior Toothpaste The raw materials of inferior toothpaste contain all kinds of inferior flavors and toxic pigments, and even industrial talcum powder that people usually use to paint walls. This industrial talcum powder has a strong stimulating effect on human oral cavity, and long-term use will lead to oral ulcer and gingival bleeding, which directly threatens human health.
Gingival bleeding is one of the common symptoms in stomatology, which refers to a small amount of bleeding caused by spontaneous or slight stimulation of gums. In light cases, bloodshot saliva appears only when sucking, brushing teeth and chewing hard objects, and in severe cases, bleeding is more or even spontaneous when the gums are slightly stimulated.
Generally speaking, chronic inflammation of gums is a common cause of gingival bleeding, so gingival bleeding is more common in patients with periodontitis and gingivitis; But sometimes it can also be the oral manifestations of some systemic diseases, so we should pay enough attention to it at this time.
Fake toothpaste not only greatly damages the image of genuine toothpaste, but also, as a product in direct contact with the oral cavity, the bacterial content of fake toothpaste seriously exceeds the standard, which will endanger human health.
