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.

The main differences between baby teeth and permanent teeth

Unlike 28 permanent teeth, the primary dentition requires the presence of 20 units. At the same time, they have a number of characteristic features.

Smaller in size compared to permanent teeth.
White with a slightly blue tint (permanent units have a slightly yellowish tint).
Less developed and slightly short roots compared to permanent teeth.
The enamel of primary teeth is poorly formed - thinner.
Milk units can be erased (permanent ones can too, but this is considered a pathology).

As the child grows, baby teeth fall out on their own - this is the norm. The permanent dentition units should not fall out on their own.

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.

How to tell the difference?
Is there always a change?
Are there baby wisdom teeth?
Can milk root remain in the gums?
When does radiography come to the rescue?

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 does teeth change?

The rudiments of future permanent units are located under the root of the baby tooth and are separated from it by a thin bone septum. At 6–7 years of age, osteoclasts of the connective tissue surrounding the baby tooth dissolve the mineral component of the septum and destroy it. At the same time, the pulp of the temporary unit is gradually transformed into granulation connective tissue rich in osteoclasts, which gradually destroy the dentin of the primary tooth. At the same time, the roots of the temporary units dissolve and, in fact, only the crown of the baby tooth remains. It can be easily removed on its own, with the help of the dentist’s manipulations, or it can be pushed out by an actively growing molar (permanent) tooth.

Anatomy of permanent teeth The permanent units of a child (and an adult) have a complex anatomy.

Visually, the tooth consists of three parts - crown, neck, roots.

The crown is the visible part of the tooth that rises above the gum.
The neck is the part of the tooth at the gum level, in the place where the crown meets the root, and the enamel of the unit turns into cement.
The root is the part of the unit invisible to the eye, located in the alveolar socket. The base of each unit is made of dentin, a hard tissue. In the coronal part, dentin is covered with enamel, and in the root part there is cement. Inside the dentin is the dental pulp - loose fibrous soft connective tissue, penetrated by a large number of blood and lymphatic vessels and nerve endings. Passing along the root canal, through the apical foramen located on the upper part of the root, they communicate with the main neurovascular bundle, providing nutrition to the tooth, drainage of excess fluid and its innervation.

Normally, by the age of 13, when a permanent bite is formed, a child has 28 permanent teeth. At the age of 17 - 25 years, third molars (wisdom teeth) erupt and the number of units may increase - 32 teeth.

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. 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.

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.
