What do we know about teeth? Most of us know only that teeth need to be cleaned regularly, and it is advisable to have periodic check-ups with the dentist. To learn more, we suggest that you familiarize yourself with the most interesting facts about teeth.
Why are the first teeth called milk teeth?
Modern science knows for certain that the rudiments of teeth begin to form even in the womb. In the first weeks of a baby's life, of course, there can be no question of full-fledged molars - he does not need them yet. But why were the first teeth called milk teeth? It turns out that they were called so by the notorious Hippocrates, whose oath is still pronounced by medical students. It was he who proposed the theory according to which the first teeth begin to form from mother's milk, because they erupt during the period breastfeeding. Since then, our first 20 teeth have been called milk teeth, although milk has nothing to do with their growth.
Teeth are not restored!
A popular proverb warns against excessive nervousness, because " nerve cells are not restored." In fact, neurons are able to regenerate, although this process occurs very slowly. But in our body there is the only organ that really “cannot be restored” - teeth. From the moment milk teeth are replaced by molars, they remain with us for life. And they cannot overcome the emerging problems “on their own”. Therefore, the last thing you should save on is visits to the dentist.
Stronger than steel
Precisely because teeth cannot regenerate, they are made up of the hardest tissue in the human body. Tooth enamel is slightly inferior in strength to diamond, but it can easily be compared with some types of steel. Enamel is a protective barrier that ensures the safety of the tooth, prevents destruction from mechanical stress and the influence of food acids. Numerous attempts by scientists to create a similar material with the same properties were in vain. The crown - similar to tooth enamel - can withstand a maximum of 15 years, while the enamel is able to maintain a "working" state for all 60.
Calcium reserves
Almost all of the calcium in our body accumulates ... no, not in the bones. 99% of it required substance contained in the teeth. That is why stories about emerging problems with teeth in pregnant women are passed down from generation to generation. Teeth during pregnancy can really deteriorate, but only if the body does not receive enough calcium "from the outside." The growing body of the baby will take from the mother everything that he needs. Therefore, teeth, as the main "reserve" of calcium, suffer in the first place.
Freshen your breath... fan
Paying attention to historical facts, you can find a lot of amazing things related to ideas about teeth, how to care for them and fight against backfire lack of proper treatment. For example, an unaesthetic appearance of teeth or bad smell from mouth. Both problems at a time when toothpaste was not common, they were solved simply - with the help of a fan. The fan served not only as a salvation in the stuffy court halls. Often they coquettishly covered their mouths to hide the lack of teeth in their mouths. And if they were still in place, but were not healthy, the inevitable bad smell was driven away with a fan.
Wrinkles from chewing?
During the reign of Louis XI, the myth became widespread that thorough chewing food leads to premature wrinkles. Therefore, those who wanted to keep the elasticity of the skin of the face as long as possible preferred food that did not need to be chewed, but rather simply “drink”. Surely it was this prejudice that gave impetus to the development of such a trend in French cuisine as the preparation of cream soups. Their grated texture is very reminiscent of the "liquid" food favored by 15th-century French dandies.
Dentist training
Aesculapius, reminiscent of dentists, existed in Ancient Egypt. However, graduates appeared for the first time only in 1699 - it was a limited edition of the French medical college. However, the extraction of a damaged tooth is still for a long time remained an undesirable procedure, which was used only in the last resort. There was little pleasant in it, and dentists-dentists trained daily for several hours - they pulled out nails driven into the board.
Jewels in the teeth - vintage jewelry
The fashion to decorate teeth with all sorts of semi- and precious stones originates from ancient times. The South American peoples have achieved special mastery in this. The Incas, for example, made dental implants from the shells of sea mussels - this is confirmed by a skull fragment found by archaeologists in what is now Honduras. From other Inca skulls found, it can be said that amethyst and quartz implants were also considered popular. The Peruvian Museum has a skull in which all 32 teeth have been replaced.
And the ancient Maya, on the contrary, preferred only to decorate, and not to replace them with stone products. 2500 years ago they encrusted their teeth with precious and semi-precious stones. Such jewelry, just like today, demonstrated the wealth and prosperity of their owner.
Fashion for "tooth" jewelry throughout human history has returned several times. So, during the time of pirate maritime domination, the favorites of the "sea wolves" flaunted their teeth made from the purest diamonds. Unfortunately, there is no information about how comfortable such teeth were. Today, dental inlay is experiencing a new round of popularity. Show business stars especially like to “shine” their teeth. Britney Spears, Beyoncé, Lady Gaga and many others put small "pebbles" in their teeth.
The most expensive tooth in the world
The natural tooth is still recognized as the most valuable in the history. Its fabulous price is due to the outstanding achievements of its original owner - Isaac Newton. This tooth was sold at auction for more than three thousand dollars by a certain aristocrat who wished not to disclose his name. The lord planned to insert the acquired “artifact” into the ring so that he would never part with it.
Therefore, it makes sense to take care of your teeth, it is quite possible that someday they will cost a fortune!
As a rule, most people's knowledge about teeth comes down to basic principles care for them: brush twice a day, preferably for two to three minutes, do not eat a lot of candy and nuts, less sweet. For you, perhaps, this knowledge will be supplemented by scripts for commercials. Do you remember the advertisement of one of the toothpastes, where with its help eggshell become hard as a rock? Well, how can I forget that? For credibility, it was not enough just to break the steel door of the safe with this egg.
In general, if your knowledge of teeth is limited to only short text on toothpaste packaging and TV commercials, BroDude is ready to fix it. We will tell you about some interesting facts related to teeth.
1. Teeth are the only part of the human body that does not have the property of regeneration. Unlike other tissues in our body, they do not regenerate themselves. And when dentists say that teeth should be treated with care, they are not just pouring a commercially profitable stream of speech into their ears. Therefore, we recommend that you respect the uniqueness of your teeth and do not neglect visits to the dentist.
2. The state of bite has a close relationship with musculoskeletal system. If the patient has malocclusion, then in almost 90% of cases this means that he has problems with his back, and in various parts of the spine: cervical, thoracic, lumbar, sacral, and so on. How is this related? The fact is that the human head has its own mass and center of gravity. When the center of gravity shifts, problems with posture begin, which is stabilized due to compensatory mechanism muscles and ligaments of the maxillofacial system, which leads to an increase in malocclusion (jaws are displaced relative to each other). modern medicine offers several ways to align the bite. The most convenient and aesthetically acceptable option can be considered the use of a transparent aligner (cup). With it, orthodontic correction is painless and effective.
3. Since teeth have only one life, nature has endowed them with unique strength. The presence of calcium in a human tooth is so great that its strength is comparable to some types of steel. This allows the enamel to be resistant to external influences, food acids and remain intact throughout human life.
4. Saliva plays the role of protecting tooth enamel. It contributes to the preservation acid-base balance. Well, since about 500,000 liters of saliva are formed in the oral cavity during a lifetime, our teeth are under reliable protection. By the way, with age, the amount of saliva secreted decreases, which leads to the vulnerability of the teeth in the elderly.
5. One more interesting fact associated with caries. This dental disease always existed, but became most widespread in the 19th century. This is due to the sharp reduction in the price of sugar, which has become much more often used in the diet of people. The historical fact I must once again remind you that eating a lot of sweets is harmful not only for the figure.
6. Perhaps the profession of a dentist is much older than we think. At least this is indicated by evidence found during excavations of dental prosthetics in ancient Egypt. The technology of prostheses resembles today's dental bridge, and they were made of precious metals. Also, the use of dentures took place in Europe even before the birth of the Roman Empire.
7. Braces were among the first to be used by British soldiers. It was a metal structure that was worn over the teeth, but not for the purpose of aligning them. Thus, the soldiers tried to protect their teeth from the blows of the enemy. Maybe it was worth giving the soldiers weapons so that they would not be beaten?
8. The first case of using a protective cap in sports dates back to 1913. Then the English boxer Gershon Mendeloff for the first time in history went to the fight with a rubber plate in his mouth, which became the prototype of today's caps. By the way, this way Teeth protection is used not only in martial arts. Caps are worn by players in American football, men's lacrosse, hockey. The latter, by the way, is the most dangerous sport for the teeth. According to statistics, 68% of professional hockey players have lost at least one tooth during their career.
Today, mouthguards are used not only to protect teeth. If you've never heard of aligners, you'll find out now. The aligner is a clear mouthguard made from polymer material and designed to align the occlusion. Aligners are currently the best alternative braces, technologically leaving the latter far behind.
If you are thinking about straightening your teeth, you should no longer be afraid of metal braces, whose vocation is to spoil any photo of their owner. The aligners are transparent and tightly fit the jaw, making them invisible when worn. And you don't have to prepare for a long and unpleasant period habituation, as in the case of braces, which cause great physiological discomfort. Once you put on the aligner, you will forget about it after a couple of hours. Additional convenience is provided by ease of use when putting on and taking off the mouthguard. It is not a constant burden to be carried around the clock. The aligner can be removed before eating or brushing your teeth.
Since the process of creating aligners is responsible and high-tech, it is very important that they are created by the best specialists. The experience of many of them confirmed that in comparison with the main suppliers to work with " star smile» the most reliable and simple. Aligners "Star Smile" are presented in clinics in more than 70 cities of Russia. On the company you can choose a suitable clinic where you will receive free consultation at the orthodontist. He will conclude whether the aligners can solve your problem.
Treatment begins with diagnostic imaging, photographs, and dental impressions. This data is sent to a 3D occlusion modeling lab. The computer calculates the treatment process and demonstrates the final result. You will immediately see what your smile will look like at the end of the treatment. After the 3D model is developed, a set of individual aligners is created. They will need to be changed every two weeks. After the specified period, which is determined at the modeling stage, you will receive a long-awaited beautiful smile.
