Around 65438+70s, William Addis of England was imprisoned for inciting riots. One morning, after washing his face, he did what many people did at that time, that is, wipe his teeth with a small cloth, because people have cleaned their teeth like this since ancient times.
But one day, an idea flashed through Addis's mind. If holes are drilled in the bones left by him when he eats meat, he will go to the guards to find some hard bristles, cut them off, tie them into a small cluster, and stick one end of a small cluster in these holes. In this way, Addis Ababa made the world's first toothbrush.
Because of Addis's invention, people not only use a small piece of cloth to clean their teeth. They can use the toothbrush invented by Addis to clean the gaps in their teeth, so that they can clean their teeth more effectively. After that, people did not stop there, but constantly refined and improved toothpaste to make it more conducive to our teeth cleaning.
Up to now, the development of toothbrush has not only stopped at manual toothbrushes, but also developed electric toothbrushes. The invention of electric toothbrush helps us to clean the internal hygiene of teeth. The cleaning power of electric toothbrush is 10 times that of manual toothbrush. It can clean teeth more deeply, and it won't be different in weight like a manual toothbrush. Its strength is stable and even, and it can instantly decompose toothpaste into very delicate foam, fully cleaning our teeth. This is the many benefits that toothbrushes bring us.
