The use of dentifrices 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, they were still made of bovine bone meal and squid bone meal. Brush your teeth with salt and rinse your mouth with salt until 2 1 century.

The above introduces a kind of powder that can brighten teeth. When it meets saliva, it will turn into paste, which can clean teeth. Its ingredients are: 1% ounces of rock salt and dried iris, 2% ounces of mint and 20 peppers.
