Funny Holidays - Toothbrush Birthday

Every morning, first thing we go to the bathroom, where we finally wake up after washing and brushing our teeth This obligatory ritual is practiced until it becomes automatic, but how and with what did you brush your teeth before? Man has taken care of oral hygiene since time immemorial They used all kinds of devices for this - from pieces of fabric to special brushes made from branches and sticks Such personal hygiene products could not always be called convenient, but several centuries ago mass production of toothbrushes began, which had the same design as the ones we use today June 26 marks the birthday of the toothbrush - a personal hygiene item that modern people can no longer do without It is believed that the idea of ​​its creation came to the mind of the Englishman William Addis, a rebel who paid for incitement and went to prison in 1770 Perhaps he had too much free time there, so Addis decided to make a toothbrush for himself The handle was a bone, in which he made several holes, and through them he passed tufts of stiff bristles and secured them with glue When Addis was released, he founded his own company called Wisdom Toothbrushes, which is still in operation today Exactly ten years after his brilliant invention, Addis launched mass production of toothbrushes, but the Englishman did not acquire a patent for them Instead, in 1850, an American did it, whose company five years later began producing toothbrushes with bone handles and boar bristles, but the device turned out to be not very practical The problem was the choice of bristles The Siberian boar had bristles inside the cavity Germs got into them The bristles themselves took a long time to dry, creating ideal conditions for the active growth of bacteria Such a brush could not be called hygienic In fact, calling Addis a “pioneer” would be a misnomer Similar devices existed several centuries before the “official” invention by the Englishman Brushes with animal bristles and bamboo sticks instead of handles were actively used in China in the 15th century Subsequently, several such devices came to Europe, but no one tried to switch from handicraft to mass production Addis was the first, which is why he appears in the history of the toothbrush as an inventor In 1938, a real breakthrough in the field of toothbrush production was made by the well-known Oral-B company Instead of animal bristles, which became a breeding ground for bacteria, artificial bristles made from nylon were used These are exactly the brushes called Miracle Tuft Toothbrush that Oral-B presented After a while, they made another breakthrough and improved the brush production technology - the tips of each bristle began to be carefully ground, polished and rounded A similar solution is still actively used today Modern brushes differ in the degree of stiffness of the bristles, which in turn is determined by the thickness and mobility of each bristle Animal bristles are no longer used in this industry at all The handles have also been completely redesigned Modern toothbrushes are made of plastic The material is usually covered with a soft rubberized layer on top for greater comfort Also in use today are electric toothbrushes that run on batteries This is a convenient device that perfectly cleans the oral cavity The first electric toothbrush was created in 1939 However, this “pilot version” required serious revision It entered mass production only in 1960 with the release of a new, improved Broxodent model
