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.

Is there always a change?
Not a single child's tooth should be preserved - they all fall out. Instead of each temporary one, a permanent one is cut through. But it also occurs in dental practice that the rudiment of the root unit is missing. This can be seen in the X-ray of the jaws.
In this case, the life of the baby tooth is extended to the maximum - after all, nothing will grow in its place. When an empty space appears in the dentition, the issue of prosthetics is discussed.
To eliminate partial congenital edentia, you can implant an implant or install a dental bridge. In the first case, there is no need to file adjacent teeth. The doctor, under local anesthesia, installs an artificial titanium root into the jaw tissue. When it takes root, it fixes the dental crown.
In the case of a bridge, it is necessary to depulpate and prepare the neighbors . This is not very healthy, since their service life after such manipulations is significantly reduced. Therefore, young patients who do not have separate molars are recommended by dentists to resort to implantation.
Funny tooth with brush and paste
It is very important to teach children hygiene, including oral hygiene. And it is equally important to do this in a form accessible to children. For example, in creativity. To do this, you can, for example, learn to draw human teeth. With a brush and ready-made paste.
The first step is to outline the shape. We draw in general, as in a school biology textbook.
Then we will draw a muzzle for the tooth. After all, this is quite a cartoon character telling children about the rules of dental care. So let's give him big eyes, slightly raised eyebrows and a joyful smile.
Now let's draw two small hands. In them, the tooth firmly holds the toothbrush and tube of toothpaste.
Let's color the drawing. The tooth will be white (except for pink gloves and a smile). Both the brush and the hose are blue. But let's make the bristles on the brush bright orange for contrast.
Our painting is now completely complete. You can hang this photo in the bathroom so that your child does not forget about oral hygiene in the morning. It also helps cope with childhood fear of the dentist.

Children's milk and permanent teeth raise many questions from their parents.
The most attentive mothers and fathers try to clearly monitor the change in temporary bite. It happens that they do not understand whether the baby’s milk units remain in the baby’s mouth or are no longer there. How to determine whether a molar or baby tooth is? To do this you need to have certain information.
How to find your angle?
First, figure out how wide your mouth can be. It all depends on the condition of your mouth and the health of your teeth. Smiling in front of the mirror, you can understand this moment. You should have a natural, relaxed smile that will highlight your best features. The mirror will help you with this like no other.
Notice what your gaze is doing now. Squinting your eyes slightly will complement your smile with naturalness and sincerity. This is an excellent solution for those who want to divert attention from imperfect teeth. The Duchenne smile is a heart condition that cannot be simulated. Be honest.
Wear colorful jewelry that may draw attention away from your lips. Unusual earrings with stones are perfect for this. Create an interesting hairstyle, wear a scarf or other fun accessory.
Ask a friend to take photos of you from different angles. Using the finished photographs, it will be easier for you to understand from which side and at what angle it is best to photograph in your case.
Be happy and bring happiness to others!
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 to draw a mouth and teeth
Step #1.
Many people struggle with the task of drawing a mouth. In this tutorial I will demonstrate how to draw a realistic mouth. I started with a simple sketch. Determine in your drawing where the lips, teeth and gums should be.
Step #2.
I applied graphite to the part above my upper lip. The shades become darker the closer to the corners of the mouth they are. Don't spend a lot of effort on accuracy in applying the shadow here, because... this section will be further developed later. Just “tweet” a couple of shades lightly.
Step #3.
Using a shading pencil, I made transitions of graphite shades.
Step #4.
I continued with my upper lip. The underside of the upper lip is always darker than the other parts and I filled it in with a 3B hardness pencil.
Step #5.
Still using the 3B pencil, applying only light pressure to the paper, I filled in the left side of the lip.
Step #6.
Continuing, I finished drawing the right side. Now you can slowly see how the drawing takes on a tridimensional form and look realistic.
Step #7.
Now I started working on the gums with Pencil B. Remember that they should be darker than the teeth, so try not to make them too light.
Step #8.
The next stage was the teeth. I noticed that many people who start drawing think that teeth are white. But that's not true. The only white on the teeth can only be highlights. Teeth have amazing highlights, so look exactly at the original reference and paint around them. If the highlights aren't as visible as you'd like, darken the areas around them slightly. For the teeth I used a 2H pencil.
Step #9.
I worked on each tooth separately. When I got closer to the front teeth, I applied less pressure with the pencil to the paper, since the saoni should be the lightest.
Step #10.
I continued working on the teeth. They take a lot of time, but in the end, the results are worth it.
Step #11.
I mastered my teeth and moved down to my lower lip. Drawing the lower lips may be a little difficult, because... they come from many different shades. To start, I applied the darker shades with a 3B pencil.
Step #12.
I continued to draw the lower lip, strictly paying attention to the variety of shades. The right side of my drawing is slightly darker than the left. Of course, this is not always the case - in this case it was simply my choice.
Step #13.
Here is the finished drawing of the mouth. The part under the lower lip is always dark. Next, the lip contour was lightly blended into the surrounding skin. Now all the shades can be adjusted and more details can be added to the picture.

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.
Is there a difference?
It happens that, trying to determine which children have milk teeth, mothers make a significant wave of their hand and say that there are no differences between the new and old units. In fact, they are.
Dairy
They take their places for closer to two to three years. The very first ones erupt when the baby is 6-12 months old. There are only twenty primary teeth (while there are 32 primary teeth). Therefore, they are arranged in a row quite freely. As the jaw grows, the spaces between them increase significantly. This can be seen with the naked eye.
At the age of 5-6 years, temporary teeth begin to loosen and fall out. This process is completed by the age of 10-12 years.
Indigenous
They appear at five or six years old or a little later. First, molars grow , which become “sixes”. After this, the incisors begin to wobble. They are pushed out by a constant shift.
Children with permanent dentition usually have 28 teeth. The four terminal units (which are popularly called “wise”) usually appear after 20 years. For many, it grows at 30-40 years old. And this is the norm.
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. Only then will you be able to get out of bed and start your morning routine. It is very important that this seemingly insignificant ritual becomes everyday. When you start thinking positively, you will see how your life will soon change. Smile, laugh as often as possible, and not just in front of the camera.
We hope that after reading this article, you received the answer to the question of how to smile beautifully and will be able to shine with a radiant smile. And one last piece of advice. Look at the smiling face of the child, kind and sincere. Babies cannot smile under duress, which is why their smile is so real. Try it and you will follow their example. 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.
Structure of a wisdom tooth –
As we said above, the crown part of a wisdom tooth differs little from the crowns of other large molars (molars). In this case, it is more difficult to answer the question - how many roots does a wisdom tooth have? there may be two, three, four, or even five. On the other hand, there are eighth teeth with one large root. But if you take a closer look at such a root, you can usually see that it consists of several tightly fused roots at once (Fig. 3-4).
How is a wisdom tooth different from other teeth?
- firstly, wisdom teeth, as a rule, have strongly curved roots.
- secondly, curved roots mean that such teeth will have highly curved root canals and, accordingly, this makes them difficult when filling is necessary (for pulpitis and periodontitis).
What does a wisdom tooth look like: photo
In the photo, notice that some roots curl into a boot shape or several roots spread widely in different directions. This shape and position of the roots makes wisdom teeth extremely unpleasant for dental surgeons, because the curved roots often break off when the tooth is extracted, and then they have to be literally “plucked out” from the bone tissue. Read and see our article about how they are removed: → “Removal of wisdom teeth”
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.
