Unknown things about brushes and toothpaste

The use of toothbrushes and toothpaste for oral hygiene is done daily by people. But history invented them, not everyone knows. Let's learn about the interesting biography of brushes and toothpaste through the following article.

How was the toothbrush born?

Many scientists have likened the human mouth to a zoo, which crowds a few hundred different types of healthy microorganisms , especially in the back of the tongue.

These microorganisms live on the food we consume left over in our teeth. They act on food, creating some acid and odor.Acid erodes tooth enamel, leading to tooth decay and tooth loss. The smell of sulfur makes the mouth smell unpleasant when speaking, when breathing, when ' mi ' each other.

The toothbrush and toothpaste work together to keep teeth clean and remove harmful microorganisms located in the mouth. Since ancient times, human beings have become aware of the negative effects of food left in the mouth after every meal.

Therefore, after eating, Asians as well as Europeans and Africans have washed their hands, washed their faces and rinsed their mouths. With a sip of full water, they used some muscle fibers in their cheeks to make the water float, spleen through the teeth, and remove sticky food here. Using your index finger, people rub their teeth back and forth. Sometimes tools use a towel or a small cloth to clean teeth.

China is regarded as the birthplace of the first toothbrush on earth, made with horse mane mounted on a bamboo or animal bone handle. It was around 1498.

In India , they used the branches of Neem or Da trees in the past , biting a soft head and then cleaning their teeth. Muslims clean their teeth by chewing roots or branches of Arak trees , a plant that contains natural antiseptic.

In 1780, a British citizen, William Addis saw rubbing his teeth with an inconvenient salt cloth. He made a toothbrush by punching a lot of small holes in a piece of animal bone and threaded it into many short, hard cow tail hairs , cut to equal to brush his teeth. Currently his descendants have a very large toothbrush production facility.

By 1857, the first patented toothbrush in the United States was granted to Mr. HN Wadsworth . The more advanced design features a bone-shaped handle with holes drilled and attached to the Pig's hair . Wild boar hair is not an ideal material, it retains bacteria, it is not very dry, hair often slips off the brush. It was not used until World War II, however, the concept of brushing was actually captured in the US, because it seemed to have become part of the responsibility of the American soldier to defend their teeth. It was a practice that they brought home after the war was over.

The 1899 photo shows how to use the brush.

In 1938, Dupont Company used nylon fiber as a replacement brush for animal hair. The reason is that fur is increasingly scarce and many people are afraid of unsanitary infections. However, wild boar feathers are still popular because they are rare and natural.

By 1939, Switzerland began producing electric toothbrushes.

In the United States, Broxodent electric toothbrush was introduced by Squibb Pharmaceuticals in the 100th Anniversary of the American Dental Association's Congress in 1960.

In 1961, General Electric Company launched a wireless electric brush market. Further progress is that the rotating brush Interplak is sold to the public in 1987. Electric brushes are very convenient for people who have difficulties in using their hands, such as osteoarthritis, consequences of brain complications.

In 2003, a public opinion poll said that toothbrushes were considered the number one necessity in people's lives, more popular than cars, computers, and mobile phones.

Today, toothbrushes are manufactured in different shapes, sizes, colors, but are basically rolled with brushes made of synthetic plastic. Plastic fibers can be hard, soft, straight or slightly curved brush heads to work in deep areas of the mouth.

Experts agree that any soft brush works if used correctly.

Many scientific studies have concluded that, using a proper toothbrush, the right method can prevent tooth decay, gingivitis and jaw . This is one-third of the causes of adult tooth loss.

Brushing usually only removes 70-80% of dirt on the teeth, the rest must be used to dental floss . Thread instead of the use of traditional toothpicks that are sometimes used improperly can cause bad effects on the gums. Silk thread is sold on each roll or short fiber on a small plastic frame. Only large and small diameters vary according to needs. Sometimes manufacturers impregnate only antibiotics, fluoride, aromatics.

Toothpaste

According to archaeologists, toothpaste was used in India and China from 500 BC. In the past, people used to scatter animal bones, egg shells and mussels to rub their teeth. Then toothpaste powder is produced from grass plants, charcoal with some aromatic substances.

It was not until 1824, a dentist named Peabody thought about adding soap to toothpaste to get lots of foam. Today, soap is replaced with Sodium Lauryl Sulfate, and Sodium Ricinoleate.

In 1850, John Harris added limestone to ice cream.

In 1892, Dr. Washington Sheffield in Connecticut, thought of putting toothpaste into a foldable tube. Previously, ice cream was contained in porcelain jars, in the form of pastes, powders or clumps into small, round circles wrapped in cellophane that looked very beautiful.

By the 1960s, Colgate began mixing fluoride into cream to maintain good enamel.

Each manufacturer has its own formula for their products, but in general creams have active ingredients with the following main effects:

Fluoride: Perhaps fluoride is the most important because it blends into the enamel, helping enzymes to resist acidic erosion in food as well as bacteria.

Color abrasives and abrasives are applied to the teeth, making the teeth more shiny. They are calcium phosphate, calcium carbonate and silica. The content of these substances should not be too much to avoid excessive enamel wear.

Detergent like sodium lauryl sulfate makes foamy cream, keeps cream in the mouth and does not flow out of the brush. It can also cause mouth sores in some people who are sensitive to chemicals.

Lasers are also tested to eliminate hidden bacteria in the roots. Research results of Dr. Ulrich Schoop, Vienna Dental University, published in the Journal of the American Dental Association, July 2007, said a special laser can kill E. bacteria. coli and E.faecalis. He suggested using lasers to disinfect and clean teeth.

Care for healthy teeth to digest food, white and shiny to have a bright, intact smile is an art. Because ' the hair is the corner of a human hair ', both in terms of aesthetics, dialogue and nutrition.
