How did ancient people brush their teeth?

In the late Tang Dynasty, Yang Liuzhi was soaked in water. When you want to use it, you bite Yang Liuzhi with your teeth, and willow fibers will come out, just like tiny wooden comb teeth and a convenient toothbrush. This is how the old saying "chew gum in the morning" comes from.

According to ancient records, by the Southern Song Dynasty, there were already shops specializing in making and selling toothbrushes in the city. At that time, the toothbrush was made of bone, horn, bamboo, wood and other materials, with two rows of holes drilled in the head and ponytails planted on it. It is very close to the modern toothbrush.

In the Song Dynasty, a substitute similar to toothpaste appeared. The ancients boiled "ancient toothpaste" with poria cocos and other medicinal materials, which was used to gargle in the early days. If you are afraid of being dirty, you can use your fingers instead of the current toothbrush. Otherwise, you can use the Yang Liuzhi mentioned above and dip it in ancient toothpaste to clean your teeth. You can also use cloth, fingers or the ancient toothbrush mentioned above, dip in green salt, wipe your teeth, and then rinse your mouth with clear water.
