Wisdom teeth - photo, how many of them a person has, why they are called that

From this article you will learn:

why is wisdom tooth called that?
how many teeth does a person have?
What is a dystopic and impacted wisdom tooth?

Wisdom teeth are the last 8 teeth on each side of the dentition (on the upper and lower jaw), which in everyday language are often called “eights”. If we count the number of teeth in each half of the lower and upper jaw, starting with the central incisor, then each wisdom tooth is exactly the eighth tooth. It is on this principle that the serial numbers of teeth are calculated in dentistry. Thus, it turns out that a person will have four such teeth in total - 2 on the upper jaw, and 2 more on the lower jaw.

Wisdom teeth get their name due to the fact that they erupt later than the other teeth in the permanent dentition. Most permanent teeth erupt between 6 and 13 years of age. But as for wisdom teeth, they usually begin to erupt no earlier than 18 years of age (rarely from 14 years of age), and this can happen at 20, 30, and even 40 years. Accordingly, due to the fact that this tooth most often erupts in adulthood, it is called the wisdom tooth.

Wisdom teeth on diagram and x-ray –

Thus, we already understand how many wisdom teeth a person has, and why they got their name. In general, in appearance, the eighth teeth differ little from other molars (6-7 large molars), and their differences are located to a greater extent under the surface of the gums. For example, differences relate to high variability in the number of roots and their shape. It should also be noted that the eighth teeth more often than others have an eruption pathology, and a little less often - an incorrect position in the dentition. Such wisdom teeth are called impacted or dystopic, respectively.

Drawing a smiling sun

First we draw a circle, it will be the basis of the image. You can use a compass or trace an object (such as a coin).

Now let's designate the location of the spokes. They can be depicted in different ways: lines, stripes, in the form of trapezoids, triangles, in the form of drops, sunflower petals. The rays can be of different sizes, so the sun will look even more interesting. Choose the shape you like and draw. Erase the basting lines with an eraser.

To make the sun friendly and optimistic, we draw joyful eyes, a small nose, eyebrows and a smile. It can be depicted as a line with raised ends in a U shape in a semicircle. Or you can use the example in the article and look at the photo on how to draw a sun with a smile that reveals your teeth. Add freckles, a bow and handles to make the lamp even more beautiful. Draw all the contours again so that they become lighter and color the drawing.

Smile with uneven teeth or no teeth

Not everyone has been blessed by nature with beautiful, straight teeth. And some of them died during their lives. But expressing joyful emotions, everyone smiles. Even without teeth. Not everyone has the financial means to clean up the mess, or are you afraid of panicked dentists? Then a closed smile is suitable for you, without exposing your teeth.

If the natural color of your enamel is yellowish and you cannot cope, you need to visit a dentist and undergo a hardware whitening procedure. This is the only way to achieve the desired white color. And all the tricks with toothpaste remain just a successful PR move.

Practical advice

Find the time, finances and courage to get your teeth in order. The most fervent laughter consists of opening your mouth and exposing your teeth. Otherwise, you will have to constantly cover yourself with your palm.
Only a sincere smile can attract and bewitch. If you smile with bad intentions, it will look like a smile and others are unlikely to like it. Your eyes should laugh too, because they are called the mirror of the soul.
Train your facial muscles. In front of the mirror, try to smile so that symmetry appears on your face. It may not work out the first time. When you achieve the desired result, look at the symmetrical smile for a couple of minutes. If you do this regularly, your facial expressions will become accustomed and your muscles will hear you more clearly.
Take care of your lips. If you don't wear makeup, apply lipstick and give up the bad habit of constantly licking your lips.

Why are baby teeth needed?

Milk teeth are involved in the development of functions in the child such as chewing and pronunciation of sounds. Without them, chewing hard food would be impossible. The aesthetic component plays an important role.

Also, baby teeth hold space in the dentition for permanent teeth. The eruption of primary teeth stimulates the primary growth of the jaws. The second wave of jaw growth begins during the period of replacement of baby teeth with permanent ones. Early removal of primary chewing teeth leads to the displacement of neighboring teeth into the area of the missing one and the formation of crowding of teeth in the future!

Teeth with a simple pencil - mastering basic drawing techniques

The pencil is a fundamental tool that any self-respecting artist should master. Then we work with the pencil technique and at the same time learn how to draw a tooth with a pencil.

First, let's draw the main lines: vertical axis, horizontal axis, general shape. All this is done to ensure that the lips are symmetrical.

Then we designate the height of the teeth themselves. It shouldn't be too big because some of them will be covered by the lips.

We draw the teeth on the lower jaw, and also mark the gums on the upper jaw.

Next we will also deal with the upper jaw.

In the final stage, all additional lines must be cleared and all main lines must be carefully placed.

That's all, we completely coped with the task. It's not that difficult, right?

How does a human tooth work?

Dental students are required to make enormous amounts of detailed anatomical drawings during their studies. But we will only look at the main parts of the tooth and move on to drawing. All of them have a crown covered with white enamel. Beneath it are hidden the inner layers - dentin, pulp and nerve. Long and strong roots grow deep into the jaw from the tooth: the front ones have one, and the distant ones have two to four.

Smile from ear to ear - let's draw together

A smile is one of the sunniest and brightest phenomena. Of course, if it is caused by something good. Let's get into this fun mood and learn how to draw a smile with teeth.

First of all, draw the general contours of the lips. Since the mouth will be slightly open, draw the outline wider than when the mouth is closed.

Then we will separate the upper lip, lower lip and the space between them.

Then we will finalize the upper jaw. The teeth should not be the same size, otherwise the smile will resemble a fence.

Now let's repeat the same with the lower jaw. Only here the size of the teeth will be slightly smaller.

After that, let's color our drawing. Let's make the lips a rich red, the inside of the mouth pink, and the area around it a pale pink.

That's it, we completed the task.

Timing and order of eruption of permanent teeth

Normally, the eruption of permanent units occurs 3 to 4 months after the loss of baby teeth. In girls, this process occurs a little earlier and faster than in boys. In both sexes, the first lower molars appear first. Then the sequence of eruption of permanent teeth is approximately the same as for milk teeth and looks as follows.

6 - 7 years - central incisors.
7 - 8 years - lateral incisors.
9 - 12 years - fangs.
10 - 12 years - premolars.
10 - 12 years - molars.

The eruption of the second molars completes the formation of the permanent dentition.

Advice from psychologists

One more thing should be said about the miraculous power of a smile. He is able to cheer up even the person from whom he comes from. Psychologists advise immediately after waking up to smile at yourself - warmly, dreamily and gently stretch. It is also worth thinking that the coming day will be positive and successful.

Laugh like you don't have a problem, enjoy life for whatever reason, and ignore the stereotype that Russians are people without a smile. You can change this opinion.

Functions of a smile

A person’s smile originates in the brain, in its subcortical region (limbic system). By definition, a smile is a reaction to an external stimulus. If you like something, you get positive emotions. If not, then negative.

Each emotion triggers different biochemical processes in the brain. They cause visible changes in the body. A clear example is expressive reactions. This is an external expression of emotions, proof that a person has some experiences, whether they are good or bad.

A smile in psychology is also considered an expression of emotions. If the face of your interlocutor does not express anything, of course, you will treat him with some uncertainty. Even a slight facial expression and a slight smile will change the situation for the better and can evoke love. It is not true?

A smile has other functions.

Communicative

In psychology, smiling is considered one of the ways of non-verbal communication. One of his responsibilities is to tell others what emotions a person is experiencing right now. And that is not all:

Anyone who smiles automatically inspires confidence in others and instills in them a sense of security.
Smiling and laughter are contagious. Therefore, by smiling, you can set your interlocutor in a positive mood. Often a smile appears on a person’s face even when viewing photographs of smiling people.
Using this method of conveying emotions, you can easily express everything you feel right now. We are talking not only about positive emotions, but also about sympathy, apology, contempt, etc.
A smile tells you what kind of person you are in front of you. It can be used to judge sincerity, good character, and aggression.

In addition, a smile is a corporate communication tool. Its absence can greatly interfere with communication.
