What do we know about teeth?
"Teeth in hard to reach places" is an advertising slogan, to which people have not tired of coming up with new jokes for several years. In fact, bone formations can indeed be present in the most unexpected places of the body. For example, a cancerous tumor, called a keratoma, can, in addition to lymphatic and muscle tissue, even include tooth buds.
American surgeons have learned to use teeth to solve ophthalmonological problems. A clear example is successful operation, as a result of which they restored the woman’s vision by replacing the affected cornea with a piece of the patient’s fang with a built-in artificial lens.
Ancient texts describe that the founder of the world religion, the great Buddha, had 32 bodily signs. One of them is white, standing in an even row of teeth of the same length, devoid of the slightest gaps. According to the scriptures, Buddha had 40 teeth.
One of the teeth, like the greatest relic, is kept in a temple on the island of Sri Lanka. He is hidden under the lids of seven caskets, placed like nesting dolls one inside the other. The relics are credited with miraculous powers.
If we talk about the first man on earth - Adam, then he had only 30 teeth. An interesting fact is that, according to historical sources It was the number of teeth of the progenitor of the human race that served as the basis for determining the number of days in a month.
In modern dentistry, the fact of having a supernumerary number of teeth, like Buddha, is called hyperodontia, and its lack, like Adam’s, is called adentia. But even if you are the owner of a superfluous set, you should not rush to get rid of the excess. Indeed, according to research by scientists, those in our oral cavity bone formations are directly related to memory. By removing any of the teeth, we completely lose part of our memories.
The amazing thing about baby teeth
Babies are born without teeth, although they have tooth germs deep in the jaw. Only after a few months do the roots of their baby teeth begin to grow, pushing the crown out. For many, it will be a revelation that there are cases when children are already born with incisors erupting from the gums. According to one version, this is associated with genetic disease body. In such situations, in order to protect the baby from accidentally swallowing a tooth, and the nursing mother from injury to the breast, the incisors are removed. According to historical references Such later famous figures as Napoleon Bonaparte and Guy Julius Caesar were born with erupted incisors.
An interesting fact is that baby teeth got their name thanks to the great Hippocrates. The scientist sincerely believed that children's temporary teeth are formed from mother's milk.
The entire “set,” which includes 20 baby teeth, matures by the age of 6-7 years.
If you do X-ray during this period, it will be seen that the child has a “two-story” jaw:
- the upper “floor” is occupied by milk teeth;
- “basement” in the depths of the jaw – molar crowns.
Over time, the growing roots begin to push the crowns to the surface, and they, in turn, push out the milk teeth. By the time a person reaches adulthood, the second set that appears on the surface will already include 32 teeth. Although there are exceptions when individual milk teeth remain viable and biologically active until a person reaches old age. This pathology is called persistence.
Where to put the fallen milk? Norwegian scientists suggest donating them to the baby teeth bank at the University of Bergen. They use the material collected as a donation from the parents of the babies to research and determine which pollutants cause the greatest harm to the growing body. Today, thanks to donations, scientists have about 20 thousand copies at their disposal.
Fashion trends
Just a couple of decades ago, most people believed that braces greatly spoil a person’s appearance. Today, in countries such as Indonesia, Thailand and Malaysia, braces are considered a sign of high status and wealth. And in fact, not many people can afford such pleasure. Especially when it comes to original systems with original design.
Enterprising manufacturers jumped into action and produced counterfeit braces at a relatively reasonable cost. You can install the system at home, without resorting to the services of specialists. But since 2012, the fashionable “accessory” has become banned. The reasons for this were several deaths that occurred as a result of people accidentally swallowing fallen-off parts of the system, as well as blood poisoning through wounds resulting from scratching the oral cavity with the sharp ends of metal structures.
At the beginning of the 21st century, the world was swept by the fashion of decorating teeth with flat small stones and plates - skyes. Surprisingly, the idea was actually not new. Hundreds of years ago, wealthy beauties of the ancient Incas, in an effort to make their smiles brilliant, decorated their crowns with precious stones. This is confirmed by the archaeological exhibits presented in museums. To this day, samples have been preserved thanks to tooth enamel - the most durable tissue human body, which perfectly resists mechanical stress and temperature fluctuations.
Human teeth are formations consisting of hard tissues; they are intended for primary mechanical processing of food. Teeth are also involved in the formation of speech sounds and are also an important part wide smile. We present to your attention 10 interesting facts about our teeth.
10 interesting facts about teeth
Human teeth are comparable in strength to shark teeth
The strength of human teeth is largely due to high content calcium (dental calcium makes up about 99% of the total calcium found in the body). However, that's not all. Latest research Scientists have proven that the structure of human enamel is the same as that of sharks.
The enamel covering the tooth is the strongest tissue of the human body and consists of crystals of the natural mineral hydroxyapatite, glued together by organic proteins. This unique structure prevents the formation of microcracks and makes teeth resistant to aggressive external influences.

Why are dentists never out of work?
The main problem of human teeth is that their tissue is not capable of restoration. Therefore, a damaged tooth, at best, must be repaired, and at worst, replaced with a prosthesis. But, for example, elephants regularly change teeth (up to 9 times in 60 years of life). Shark teeth are even more practical - they grow as they are worn down.
Modern dentists will never be unemployed
What are baby teeth made of?
The father of medicine, Hippocrates, called children's teeth baby teeth because he was convinced that the first set of human teeth develops from the milk that babies drink. It should be noted that the ancient Greek doctor was not as naive as it seems at first glance.
Milk contains a large number of calcium, without which normal growth of teeth – both milk and permanent – is impossible. In addition, baby teeth are indeed significantly different from permanent teeth - they are less durable and have a thin layer of enamel, so their condition greatly depends on the child’s nutritional pattern.
Milk contains a large amount of calcium, which is so necessary for the normal formation of teeth.
The muscles of mastication are the most powerful muscles in the human body.
The death grip is not limited to the jaws of fighting dogs. Chewing muscles a person is capable of creating pressure up to 3.5 centners. Such heavy load can damage tooth enamel and even break teeth, so Everyday life the forces of our jaws are rarely more than 10-15 kg.
The human chewing muscles can create incredible pressure.
Ancient dentists – the first transplantologists
Dentist is the oldest profession. Dentists were the first doctors to successfully use organs from living or dead people for transplantation. Thus, implants of human teeth (most likely from slaves or dead people) were discovered in the jaws of ancient Egyptian pharaohs. This practice was carried out until the beginning of the last century. Historians testify that after the Battle of Waterloo, the teeth of dead soldiers were supplied to many countries for the needs of dentists. Well, in our time, dental implantation is already a common operation to correct the bite.

It's not just delicious food that makes your mouth water
Our salivary glands work continuously 24 hours a day, seven days a week! On average, about two liters of saliva are released into the human mouth in one day. It is thanks to such tireless work salivary glands tooth enamel is preserved. With the so-called dry syndrome - a disease that occurs with sharp decline functions of the salivary glands, teeth can be completely destroyed in just two to three years.
Saliva not only moisturizes the surface of the teeth, but also stabilizes the acid-base balance. Increased salivation observed when food is too acidic or too alkaline - this is how saliva protects tooth enamel. In addition, salivary fluid contains bactericidal substances that prevent the proliferation of pathogenic microflora, which contributes to the development of caries.
How much can one tooth cost?
The most expensive tooth in human history was that of the famous physicist Isaac Newton. At the beginning of the nineteenth century, it was bought by an aristocrat for an amount that, in modern terms, amounted to almost forty thousand dollars. The lucky buyer placed the scientist's tooth in his gold ring.

Other peoples used products made from durable turtle shells as prosthetics. In those days, any material required great skill, so only a select few could afford such prostheses. An interesting find was discovered in South America– the jaws of the ancient Inca contained a full set of artificial teeth (32!), made of quartz and amethyst.

Therefore, we recommend that you respect the uniqueness of your teeth and do not neglect visits to the dentist.
2. The state of the bite has a close relationship with the musculoskeletal system. If the patient malocclusion, then in almost 90% of cases this means that he has back problems, and in various areas 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 by compensatory mechanism muscles and ligaments of the maxillofacial system, which leads to an increase in malocclusion (the jaws move relative to each other). Modern medicine offers several ways to straighten your bite. The most convenient and aesthetically acceptable option is the use of a transparent aligner (aligner). With its help, orthodontic correction is painless and effective.

This is due to the sharp decline in the price of sugar, which has become much more often used in people’s diets. The historical fact I must remind you once again that eating a lot of sweets is harmful not only for your figure.
6. Perhaps the dental profession is much older than we think. At least this is indicated by evidence of dental prosthetics found during excavations in Ancient Egypt. The technology of the prostheses is reminiscent of 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. British soldiers were among the first to use braces. It was metal structure, which was put on the teeth, but not for the purpose of straightening them.

8. The first case of using a protective mouth guard in sports dates back to 1913.

Today, mouthguards are used not only to protect teeth. If you haven't heard anything about aligners, you'll find out now. An aligner is a clear aligner made from polymer material and designed to straighten dental bite. Currently, aligners are the best alternative braces, technologically leaving the latter far behind.
If you're thinking about straightening your teeth, you no longer have to be afraid of metal braces, whose vocation is to ruin any photo of their owner. The aligners are transparent and fit tightly around the jaw, making them invisible when worn.

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 the best specialists. The experience of many of them has confirmed that, in comparison with the main suppliers, working with “ Star Smile» most reliably and simply.

The computer calculates the treatment process and demonstrates final result. You will immediately see what your smile will look like at the end of treatment. After developing a 3D model, a set of custom 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 the long-awaited beautiful smile.
