Interesting facts that you did not know about teeth


Sweet and sour is harmful

Sugar is not the only threat to dental health. Acids (especially citric, which is found in candies, fruit juices and carbonated drinks) contribute to its thinning (erosion). As a result, the tooth is reduced in size and the risk of tooth decay increases. Dentists daily experience enamel erosion caused by excessive consumption of overly acidic foods. Children who adore “acid” candies, sticky chewing candies and sugary carbonated drinks are especially at risk. All this simply “dissolves” the teeth, especially when you consider that in children enamel maturation ends only by 10 years.

However, adults who seem to eat more properly also consume a lot of foods with high acidity. Destructive acids are found not only in some fruits, such as mangoes, but even in soft drinks without sugar.

Doctors recommend consuming foods with a high acid content not independently, but as part of any dishes, and after chewing, chew gum with xylitol to restore acid-base balance in the oral cavity.

Enamel is the hardest substance in the body, but it can also be destroyed!

Ice, popcorn, piercing on the tongue or lip - all this can easily crack enamel, and this crack will not heal any more, as the wounds on the skin heal.

According to the dentists, gnawing ice and popcorn is the same as stone, and metal piercing jewelry not only damages the enamel every time you talk, bacteria also multiply on them. As it turned out as a result of research, from 14% to 41% of holders of an oral piercing suffer from damage to tooth enamel up to the loss of teeth.

Teeth can be lost at any age.

Some people find it cheaper and easier to remove a tooth than to treat or prosthetize it. According to statistics, on average over a lifetime, a person removes from one to 32 teeth, but there are those who are already born with their absence. Most often, these are “wisdom teeth” and the middle incisor, which is located next to the large front tooth. A symptom such as lack of teeth can be inherited, but the most common causes of tooth loss are gum disease and tooth decay.

Too much fluoride is bad for your teeth.

We know that fluoride is important for dental health. However, children under the age of 8 (at this time the formation of permanent teeth is taking place), whose body gets too much of this chemical element, may suffer from fluorosis (chronic fluorine intoxication). As a rule, its symptoms are white or brown spots on the teeth that cannot be removed simply by polishing the enamel.

Dentists claim that the cause of the development of fluorosis in children is not fluorinated water, which, on the contrary, helps to strengthen enamel, but that they swallow too much fluoride-containing toothpaste during toothbrushing. Therefore, it is necessary to ensure that the kids use fluoride-free paste until they learn to spit it out.

Braces can cause tooth decay.

If you do not want your smooth, beautiful teeth to be affected by caries, dentists recommend brushing them carefully. Otherwise, food debris, bacteria and acids accumulate in the area of ​​the braces, and the enamel in these places begins to slowly collapse. Even if it does not come to caries, the lack of proper care can cause tooth demineralization - the appearance of light spots on the enamel, which will begin to darken over time. Doctors advise those who wear braces not to forget that the tongue is a “natural toothbrush”, which should be carried out more often in the teeth, cleaning them from pollution.

1. Some babies are born with teeth.

About one in 2,000 babies is born with prenatal teeth — that is, teeth that erupted before birth. As a rule, these teeth grow on the lower gum, and they have weak roots. Often these teeth are removed so that they do not interfere with breastfeeding and do not lead to accidental swallowing. In some cases, they may indicate the presence of certain medical problems, and in the ancient physiognomy they were associated with evil forces. According to some statements, Julius Caesar and Napoleon were born with teeth.

2. Not all people lose their baby teeth

Loss of baby teeth is a natural stage in our lives. Usually, by the age of 3, children already have a whole set of 20 temporary teeth, which then loosen and fall out, after which permanent teeth begin to erupt at the age of 5-6 years. This process ends in early adolescence. But there are cases when a person does not grow permanent teeth, which is often associated with a family predisposition, he still has milk teeth.

3. Some people have too many teeth.

Approximately 2 percent of people have hyperdontia, in which additional supernumerary teeth grow in a person. Many of these teeth remain hidden under the gum, but sometimes they cut through and begin to displace other teeth. Very rarely, a person loses a permanent set of teeth at an older age and another set grows. Everyone else will need a denture.

4. The tumor can also grow teeth.

With teratoma - a tumor of the germ cells, which is often found in the ovaries, testicles and the coccygeal-coccygeal region, teeth, hair, eyes, hands, and other limbs can be found in the tissues of the tumor. Fortunately, such tumors are often benign and can be removed surgically.

5. Tooth can also be seen

In 2000, one woman in the United States underwent a unique operation. Sharon Thornton lost her sight due to Stevens-Johnson syndrome, in which the cells of the surface of the eye are destroyed. Doctors suggested restoring a woman’s vision with ... a tooth. She had her fang removed, into which an artificial lens was inserted and implanted in her left eye. A day later, a blind woman was able to see the world again.

6. Not all countries consider straight teeth to be beautiful.

Do you think that straight white teeth are the ideal of beauty recognized everywhere? In Japan, crooked teeth called yaba became very popular. At the same time, many Japanese women specifically bend their straight teeth, accenting fangs to look younger and prettier.

7. In the future we will not have wisdom teeth

Third molars or wisdom teeth helped our ancestors grind roots, nuts and leaves with a larger jaw. But now about 35 percent of people are born without wisdom teeth. The rest of the dentists recommend removing them, as our oral cavity is too small for them. When our body no longer needs any organs or parts, they become rudimentary and eventually disappear. According to scientists, future generations will not have an appendix, wisdom teeth, and possibly even little toes.

8. Raisins are more harmful for teeth than chocolate

Not all sweets are equally harmful to the teeth. Sugar from various products is a breeding ground for bacteria that create acid that destroys teeth. Foods that get stuck in your teeth, including bread, chips, dried fruits, often turn out to be more harmful than those that quickly dissolve (chocolate, chewing sweets). At the same time, it is better to immediately eat sweets than to have a snack many times during the day, constantly feeding bacteria.

9. People have been taking care of their teeth for centuries

Did you know that early toothbrushes were twigs that our ancestors chewed? Around 5000 BC e. Egyptians used chopped eggshells and ground animal hooves to clean and polish their teeth.

In 1700, a British inventor adapted the design he saw in China to a European consumer - a bone with pork bristles inserted through holes and secured with wire.

Dental prosthetics were carried out already in Ancient Egypt - implants were found in the jaws of the mummies of the pharaohs, most likely removed from slaves or deceased. And in South America, an ancient Inca was discovered, the jaw of which consisted entirely of transplanted teeth - amethysts and quartz were used as materials for implants.

Modern toothbrushes with nylon bristles appeared in the late 30s of the last century, and the first electric brush was introduced to the world in 1954.

During the operation, doctors discovered that this boy had 200 extra teethwhich caused similar symptoms. A similar anomaly was caused by a benign tumor in the jaw called an odontoma. The removed tumor and the remaining teeth are an absolute record, before that the maximum number of additional teeth formed by this type of tumor was 37.

By the way, it happens that a person’s teeth grow not only in his mouth. According to statistics, 4% of the world's population have a similar problem. So, in a person suffering from nosebleeds, during the examination, a tooth was found located in his left nostril.

3. The base of your teeth is already present on your birthday

1. Your teeth can tell about you

Scientists can tell a lot by examining a particular person’s teeth. Do you know that our teeth can show how old we are, what we eat or drink, and even where we live? Our teeth also carry a lot of information about our state of health, including data on past illnesses. In short.

For example, the nature of the bite has a very close relationship with the musculoskeletal system of a person. If the patient has an incorrect bite, then in almost 9 out of 10 cases this suggests that he has problems with his back. Why it happens?

The fact is that the human head has its own weight and, accordingly, the center of gravity. When the latter is displaced, a violation of posture is formed, which is corrected due to the compensatory mechanism of the muscles and ligaments of the maxillofacial apparatus, which leads to malocclusion.

Modern dentistry has several methods for correcting occlusion. The most simple and cosmetically acceptable way can be considered the use of a transparent eliner (mouth guard). With its help, orthodontic correction of the bite is comfortable and quite effective.

By the way, did you know that a person cannot have two identical teeth in his mouth. And it doesn’t matter if we are talking about “milk teeth” that serve us at an early age, or about 32 “permanent” ones.

Each tooth in the mouth has a unique structure. Therefore, it is safe to say that your smile is indeed a true sign of your personality!
