The birth of Mr. toothbrush
1, the budding period (before 1840) long ago, people around the world have a habit of protecting teeth and loving beauty. However, due to the technical constraints of the time, people still do not use the modern meaning of toothbrush. As a result, people around the world have found similar toothbrush alternatives in the natural world.
Alternative 1: tooth stick. In 3000 B.C., the Urumite king of the Sumerians used the first toothbrushing tool, a toothbrushing stick, for two weeks.
Alternative 2: fingers. In the Dunhuang frescoes of the Tang Dynasty of China, "the sacred pictures of the forks of Laudu", they are painted A monk squatted on the ground with a mouthwash bottle in his left hand and wiped his front teeth with his right fingers.

In distant Europe, the first toothbrush was born in 1780 or so. One morning in 1780, an English prisoner, William Adith, washed his face and wiped his teeth with a small piece of cloth. Because the cloth was inefficient and unclean, he suddenly came up with the idea of an improved toothbrushing tool: drill some holes in a bone, ask the guards for some hard bristles, cut them off, tie them into small clusters, and apply glue.
