The process of a child’s teeth appearing is always interesting to parents, so they keep track of which baby teeth have fallen out and which permanent ones have come out. However, there are situations when it is not clear whether this is baby tooth in the mouth of a toddler or already a native one. How are they different and by what signs can you recognize them?
What is the difference?
Dairy
This is the name given to the first teeth that appear in a baby before the age of 2.5-3 years. They begin to erupt in most babies at 6 or 7 months, when lower jaw The baby “pecks” at the first central incisor. Soon his “partner” also crawls out, after which the incisors are cut into upper jaw, lower lateral incisors, first molars, canines and second molars until the child has 20 teeth.
This amount will remain until about 5-6 years, after which the time will come for the eruption of the first molars.
The replacement of baby teeth with molars begins at the age of 6-7 years
Indigenous
This is the name for permanent teeth, which begin to cut on average at 6-7 years of age. The first of the molars to erupt are the molars, which occupy the sixth place in the dentition, and only after that the milk teeth begin to fall out, and their permanent replacement begins to cut in their place. At the same time, there are more molars - there are 32 of them in total, although in childhood in most cases, only 28 of them are cut through.
The last four (wisdom teeth) appear later than the others, sometimes even after the age of 30-40.
If a child only has 20 baby teeth, then there will be at least 28 molars.
How to distinguish milk from indigenous?
You can determine whether a tooth is a baby tooth or a molar tooth by its:
- Size and shape. Temporary ones are small in size and more rounded, while permanent ones are larger.
- Coloring. The color of milky ones is often white with an indistinct blue tint, while permanent ones, due to the presence of more mineralized tissues, have a yellowish tint to the enamel.
- Location. The growth of the deciduous ones occurs vertically, while the molars are slightly directed with their crowns outward towards the lips and cheeks.
Let's take a closer look at how to understand whether a baby tooth is in the baby's mouth or is already permanent, taking into account its serial number in the dentition (the number is counted from the midline outward):
- If the tooth is the sixth or seventh, then it is a molar, because there will be only five milk teeth on each side of the jaw.
- If you're looking at the fourth and fifth teeth, pay attention to the crown. The milk teeth in this place are distinguished by wider crowns and the presence of four chewing tubercles. If these are already permanent teeth, which are called premolars, they will have fewer cusps (there are only two on each tooth) and narrower crowns. In case of a controversial situation, the tooth is compared with a similar one on the other side of the dental arch.
- When deciding whether a child’s third tooth (canine) is permanent or baby, you should also take into account its shape and size. Milk fangs are smaller in size, and by the time of physiological change, their sharp tips wear out. The permanent canines are longer, and their cusp has a distinct pointed apex.
- When looking closely at the incisors (first and second teeth), first of all, their size is also taken into account. If they are temporary, their width is approximately 4-5 mm and their height is approximately 5-6 mm. In permanent incisors, the width of the crowns is larger - approximately 10 mm for the central ones and about 6-8 mm for the lateral ones. In addition, at the age of eruption of permanent incisors, their cutting edges are uneven (with small tubercles), while in deciduous incisors by this age the edge will always be smooth and even.
Do all dairy products change to indigenous ones?
In order for a child to have molars, absolutely all baby teeth must fall out. Some mothers feel that their baby molars are large sizes They are considered permanent and do not fall out, but this is not the case. They will also fall out in due time, giving the opportunity for permanent premolars and molars to erupt.
Wisdom tooth - molar or milk tooth?
Wisdom teeth are the four teeth that erupt last. Based on their location in the dentition, they are also called “eights.” Since they represent the 29th, 30th, 31st and 32nd teeth in a person's mouth, they cannot possibly be primary teeth, since there are only twenty primary teeth. In addition, they are cut after the age of 17, when not a single baby tooth should normally remain in the child’s mouth.
Wisdom teeth are undoubtedly molars.
What to do if a root grows behind the dairy?
The situation when a molar has already “hatched”, but the milk tooth is in no hurry to fall out, is not uncommon. In this case, you should wait a while, allowing the baby tooth to loosen and leave the dentition.
If more than three months have passed since the appearance of a permanent tooth, and the milk tooth remains in the gum, it is worth going with your child to the dentist.
Can the root remain in the gum?
Starting from the age of five, the roots of baby teeth begin to dissolve. This process takes quite a long time, for example, the root of each incisor is resorbed within two years, and the complete resorption of the roots of molars takes about three years. However, all the roots sooner or later dissolve, and only after that the teeth fall out, so they cannot remain in the gums.
Tooth in Latin is dentes, which is dentin covered with enamel, the strongest human tissue.
Baby teeth
At the beginning of the seventh month of extrauterine life, the crown of the baby tooth erupts; for this, the gums become thinner; the last dentes decidui grows at 2 years and 6 months. The size is smaller than that of permanent ones, with small tubercles on the surface.
The lower incisors grow first. And under each milk tooth there is a permanent bud, for this the roots grow divergent.
The number of baby teeth is always 20. The natural replacement of baby teeth with permanent teeth begins at six years of age, and additional ones gradually grow.
Permanent teeth
Teeth change only twice in a lifetime.
In dentistry, teeth are divided into 3 parts:
- crowns;
- necks;
- roots.
A six-year-old molar (major molar) is your child's first permanent tooth. By the age of thirteen, the main permanent teeth will grow, except for the molar. It grows after 18 and up to 30 years.
After which the total number is 32.
How to understand a baby tooth or a molar
The differences between baby teeth and molars are pronounced. It’s convenient to understand by remembering these distinctive parameters:
- There will always be 20 baby teeth, as opposed to 32 permanent teeth.
- Milk teeth grow up to 3 years, permanent teeth from 7 to 30 years.
- Permanent teeth are visually larger than baby teeth.
- Milk ones have a white-blue tint, while permanent ones have a yellowish tint.
- Primary teeth lack premolars and third molars.
- Baby teeth fall out without intervention, permanent teeth need surgical method delete.
- Baby teeth wear down; this is a natural process. For permanent teeth abrasion is “not provided.”
In any case, care should be carried out for both permanent and baby teeth. Proper nutrition, hygiene and regular visits to a specialist will ensure the formation.
On an ongoing basis
By the age of 6, the child’s first molars appear. The number of molars is 12, 6 for each jaw. The peculiarity of the upper molars is their large size and high strength. They have 3 roots that diverge into different sides. This ensures their reliable fastening and resistance to loads.
When a molar appears, the primary tooth naturally falls out. But sometimes there are exceptions. So, it happens that the milk has not yet fallen out, but permanent teeth are already ready to take their place.
In such cases, the child experiences pain and discomfort. In this case, it is better to immediately seek help from a specialist.
Timely assistance will prevent the new tooth from becoming crooked. Molars perform important function which involves breaking up food. This happens thanks to four tubercles on its surface.
They must be carefully looked after throughout their lives. This will preserve their integrity and functioning. Otherwise, you cannot do without the help of specialists.
When you can't do without a doctor's help
Often, changing teeth occurs almost painlessly. When teeth fall out on their own, there is no pain. But there are exceptions.
So, if a child has severe pain, itching, or increased sensitivity of the enamel, you should immediately seek help from a doctor. Excessive hemorrhage at the site of a recently fallen baby tooth should also alert you.
If a permanent tooth does not appear in place of the lost milk, then you need to consult a dentist. The fact is that treatment may be needed here.
Also in some cases there may be inflammatory processes and other complications that will cause discomfort and pain to the child. An equally important problem is improper tooth growth. In the future, this negatively affects the bite.
In fact, changing your bite is a natural process. If no pathologies or symptoms arise, then there is no need to worry.
If, when the bite changes, the temperature rises and the child becomes overly irritable, then you need to seek help from a specialist. This will quickly solve the problem and prevent complications from occurring.
How to distinguish a baby tooth from a molar
Their roots bend and diverge, which ensures a secure attachment to the jaw. Baby teeth have a characteristic shape. A cushion-shaped thickening can be observed in the cervical part of the tooth.
Another characteristic difference is the inclination of the longitudinal axis of the crowns towards the tongue and palate. Most often, it is this inclination that makes it possible to distinguish milk teeth from molars.
In the photo, the boy’s baby teeth have not yet fallen out, but his permanent teeth are already coming in
You can also distinguish teeth by their shade. The baby's first teeth are White color with a slight bluish tint. As for the indigenous ones, they have a yellowish-grayish tint. The neck of the tooth is darker.
It is also worth noting that baby teeth are less hard than permanent teeth. They are easily amenable to drilling and other manipulations carried out by the dentist for the purpose of treatment.
With this information, every parent can easily recognize which tooth is growing in the child. In the future, this will allow careful monitoring of changes in the bite.
Thanks to this, there is every chance that the child will receive a healthy and beautiful smile. If you suddenly determine that a baby tooth cannot leave the dental canal, you should immediately seek help from a doctor. This will avoid many problems, including the occurrence pain, and the child is unwell.
A beautiful smile with snow-white teeth and an even bite is the main indicator of health. Any mother is interested in the appearance and change of teeth in her child, so she carefully observes these processes. But sometimes a mother wants to understand whether a baby tooth or a permanent tooth is in the baby’s mouth. To do this, let’s look at the differences between baby teeth and molars.
The structure of baby teeth
Milk teeth are the first temporary teeth. It is believed that Hippocrates gave them their name. He believed that they are formed from mother's milk during breastfeeding.
The rudiments of baby teeth begin to develop in the womb - at 7-12 weeks of pregnancy. Their eruption begins at approximately 6-7 months of the baby’s life, and the process ends by 2.5-3 years. However, everything happens individually for each child.
The structure of baby teeth
Their structure is very similar to the structure of permanent ones, but they have their own characteristics by which they can be distinguished:
- their crowns are smaller in size;
- enamel and dentin are much softer and thinner, which often leads to the rapid development of caries;
- the pulp cavity is extensive, which allows microorganisms to develop faster - passing through the thin walls of the crown, they affect the internal cavity much faster;
- their roots are less strong and massive, making their resorption easy and painless;
- their number is 20.
Attention! The timing of the eruption of the first teeth depends on the individual development of each child. They can be affected by heredity, place of residence, the course of pregnancy in the mother, nutrition, and previous diseases.
Approximate dates for the appearance of baby teeth:
- Central incisors on the upper and lower jaws – 6-8 months. The total number is 4.
- Lateral incisors, 2 on each jaw – 8-14 months.
- The first large molars, 2 on the upper and 2 on the lower jaw, erupt at 12-18 months.
- There are 2 fangs on each jaw - cut at 16-24 months.
- Second large molars (back teeth) – 4 teeth. Teething begins at 2 years of age and is completed at approximately 3 years of age.
Attention! Primary teeth play an important role in the development of a child - they are involved in primary processing food, the formation of the facial skeleton and the formation of the bite, help the development of correct speech. Therefore, from the very first teeth, it is necessary to accustom the baby to hygiene and careful treatment of them - from the age of one year, start brushing them, limit sweets and do not forget about a timely trip to the dentist.
Signs of baby teeth erupting
In some babies, their appearance is asymptomatic, and the mother accidentally discovers the first of them in her child’s mouth. For others, this process can be painful and difficult. At this point, the child’s immunity usually weakens, which may manifest itself in the following signs:
- emotional manifestations: irritability, crying, poor sleep;
- profuse drooling;
- digestive disorders - diarrhea, vomiting;
- refusal to eat;
- increase in body temperature to 37-38°;
- swelling and pain of gums;
- the desire to put everything in your mouth - bite, scratch your gums;
- “hanging” on the chest, sucking fists.
Photo of baby teeth erupting Structure of permanent teeth
Permanent (molar) teeth are teeth that replace milk teeth. The process of loss and replacement of one with another begins at 5-6 years and ends at 13-14 years. Their total number is 32.
They have a crown, neck and root. Their fabrics are presented in layers:
- Enamel – hard fabric, protecting the internal cavity from external irritants. It covers the outside of the crown.
- Dentin is bone tissue. In the area of the crown, it is covered with enamel on the outside, and in the root with cement.
- Pulp is the soft, “living” part of the tooth. Contains many blood vessels and nerve fibers. Performs nutritional and sensitive functions.
Types of permanent (molar) teeth and the order of their appearance
Lack of vitamins accompanying illnesses or metabolic disorders can cause a delay in the appearance of permanent teeth. Also, shifts in the timing of eruption depend on the anatomical and physiological characteristics of each child, climatic conditions, nature of nutrition. They usually appear in this order:
- The first large molars (molars) appear at 5-6 years of age.
- Then comes the replacement of the central incisors on the lower jaw.
- The upper central and lateral incisors on the lower jaw emerge almost simultaneously.
- At 8-9 years old, the upper lateral incisors are replaced.
- Until the age of 11-12 years, small molars (premolars) are replaced.
- At the age of 13, the canines are replaced.
- From about 14 years of age, the second pair of molars emerges, which are absent among the primary molars.
- From the age of 15, the third molars or “wise” teeth begin to emerge. Sometimes they remain in the gums until old age.
Time frame for changing baby teeth to permanent ones Signs of the appearance of permanent teeth
Permanent teeth do not erupt asymptomatically, just like baby teeth. But due to age, a person’s immunity becomes stronger, which means the reaction will not be as acute. Their appearance is accompanied by the following signs:
- the appearance of gaps between baby teeth, which is due to the growth of the child’s jaw;
- loosening of teeth due to resorption of milk roots and their precarious position in the jaw;
- loss of the first temporary teeth - this indicates that the permanent one has “pushed” the milk one out of the gums and will soon erupt;
- swelling and pain of the gums are possible;
- loss of appetite;
- irritability.
This is interesting! There are cases when a child is born with baby teeth. They are called natal. There are also cases of the appearance of neonatal teeth - these are those that erupted in the first 30 days of a child’s life. They come complete, that is, simply cut through ahead of schedule. And there are additional ones - grown in addition to the main set. The doctor decides what to do in such cases.
How to distinguish a baby tooth from a molar
Despite the similar structure of primary and permanent teeth, indigenous people have a number of distinctive properties:
- Quantity is the main difference. The milk set contains 20 teeth, and the permanent set contains 32 teeth.
- Magnitude. Dairy products are 2 times smaller than indigenous ones.
- Color. Temporary ones have a bluish-white tint, while permanent ones have a yellowish tint.
- Dates of appearance. The first teeth erupt at the age of 6-7 months, permanent teeth - at 5-6 years of age.
- Shape and width of crowns. In dairy animals they are more pronounced than in permanent ones.
- Roots. In milk teeth they are short and tend to dissolve, while in permanent teeth they are longer and firmly attached to the jaw.
- Kinds. The set of primary teeth includes incisors, canines and molars; The permanent set includes incisors, canines, molars and premolars.
- Fabrics. The thickness of permanent enamel is 2 times greater than that of dairy enamel.
- Pulp cavity. For temporary ones it is much more extensive than for permanent ones.
Note! Baby teeth fall out on their own; permanent teeth can only be removed instrumentally.
Baby teeth Are all children's baby teeth replaced by permanent ones?
There are cases when it is possible to observe baby teeth in adults. Why does this happen? The main reasons are:
- The rudiments of permanent teeth are laid too deep in the gums and do not affect the roots of milk teeth. This happens due to a lack of free space in the gum or incorrect roots.
- Absence or underdevelopment of permanent tooth buds. This could lead to genetic predisposition, disruption endocrine system, previous jaw injuries, inflammatory processes in baby teeth.
Dentists individually determine the fate of a baby tooth in adulthood in each case. If it is not loose and in good condition, there is no rush to remove it. The decision is made after x-ray examination, which will show whether there are the makings of a permanent tooth and whether the roots of the milk tooth are preserved. It is also possible that the root will never come out.
In the case when the baby tooth is loosened, is in an unhealthy condition and in the absence of the rudiments of a permanent one, the question of prosthetics or restoration of the child’s tooth will arise. This is also observed - the makings of a permanent tooth have not emerged, but the baby tooth has fallen out. Then the orthodontist must perform prosthetics.
Are all children's teeth baby teeth?
By the age of 3, the baby should have 20 baby (temporary) teeth in his mouth. In the future, they should be replaced by permanent ones. The first ones begin to fall out when the radicals move closer to the exit oral cavity and “push” them. The breasts become loose and fall out on their own, often painlessly.
Important! When temporary teeth fall out and new teeth erupt, soft tissue ruptures may occur. Therefore, during this period it is necessary to carefully monitor oral hygiene - be sure to brush in the morning and evening, rinse the mouth after each meal, and promptly heal carious areas to avoid infection of permanent teeth.
Some mothers and fathers want to know: what kind of teeth are in the child’s mouth, have the permanent ones come out yet or are they still baby teeth? This can be determined by their configuration. The primary set consists of incisors, canines and large molars. There are no premolars in the milk series. Starting from the central incisor, towards the cheeks, there should be 5 teeth on each half of the jaw. If you find 6 or 7, these are already permanent.
The shape also matters. The temporary one has a wide crown and 4 masticatory cusps, the permanent one has 2 cusps. Primary canines are smaller than permanent ones; their sharp end is usually worn away by the time they are replaced with molars. In case of doubt, an x-ray will give the exact answer.
Healthy, beautiful teeth, regardless of their type, are not only a gift that was inherited from parents. A lot depends on careful attitude and daily care!
It's simple - this is the only organ of the human body that cannot recover on its own.
Modern and ancient teeth
In the anatomy course, the definition of a tooth is given - it is ossified part of the mucosa shells designed for chewing food.
If we delve deeper into phylogenetics, then the “progenitor” of human teeth is considered fish scales, located along the mouth. As they wear, teeth change - this is a mechanism inherent in nature.
In lower vertebrate representatives of the fauna, change occurs several times during the entire life cycle.
The human race is not so lucky; its bite changes only once - the milk teeth are replaced by permanent teeth.
Evolution has significantly changed the human jaw apparatus. U ancient man there were more than 36 teeth. And this was justified by the diet - hard raw food. To chew it, you had to work your jaw with force. Therefore, a massive jaw apparatus and chewing muscles were developed.
When our ancestors learned to make fire, they had the opportunity to process food. This made the diet softer and more easily digestible. Therefore, the anatomy of the jaw underwent transformation again - it became smaller. Homo sapiens' jaw no longer protruded forward. It has acquired a modern look.
The teeth of primitive people were not beautiful and did not form a radiant smile, but they were different strength and health. After all, they actively used them, chewing solid and rational food.
Anatomical development
The formation of teeth is a long process that begins in the womb and is completed by the age of 20 at best.
Dentists distinguish several periods of tooth development. The process has already begun in the second month of pregnancy.
Children have 20 baby teeth, an adult has 32. The first teeth are at six months, and by the age of 2.5 they are already present complete milk set. Outwardly, they are similar to permanent teeth, but there is a fundamental difference - thin enamel, large numbers organic matter, short, weak roots.
By age 6, the baby's bite begins to change. Besides, molars are erupting, which did not have dairy predecessors.
The process continues up to 14 years. And it ends only when the third and fourth teeth – “wise” teeth – erupt. You can wait for them until old age.
Structure
A tooth, as a separate element, includes identical parts. The cross-sectional structure of a human tooth can be seen in the diagram:
- Crown– visible part.
- Root– in the recess of the jaw (alveolus). Attached by connective tissue made of collagen fibers. The apex has a noticeable opening pierced by nerve endings and vascular network.
- Neck– combines the root part with the visible part.
- Enamel– hard covering fabric.
- Dentine– the main layer of the tooth. Cellular structure it is similar to bone tissue, but is distinguished by its strength and high mineralization.
- Pulp– central soft connective tissue, penetrated by the vascular network and nerve fibers.
Look visual video about the structure of teeth:
Milk teeth have the following features:
- smaller size;
- reduced degree of mineralization of layers;
- larger volume pulp;
- fuzzy bumps;
- more convex incisors;
- shortened and weak rhizomes.
With improper care of the primary occlusion, 80% of all adult pathologies develop precisely at an unconscious age. Careful hygiene of replacement teeth saves permanent teeth from many potential problems.
Types of teeth
Teeth differ in appearance and functions. Despite these differences, they have general mechanism development and construction. The structure of the human jaw includes the upper and lower dentition (2 dental arches), each with 14-16 teeth. We have several types of teeth in our mouth:
- Incisors– front teeth in the form of a cutting chisel with sharp edges (8 in total, 4 on each arch). Their function is to cut pieces of food to the optimal size. The upper incisors have a wide crown, the lower ones are twice as narrow. They have a single cone-shaped root. The surface of the crown has tubercles that wear away over the years.
- Fangs – chewing teeth designed for separating food (4 in total, 2 on each jaw). On the back side there is a groove dividing the crown into two unequal parts. The crown itself is cone-shaped due to one pronounced cusp, so these teeth look like animal fangs. Canine teeth have the longest root of all teeth.
- Premolars– these are small molar chewing teeth (4 on each jaw). They are located behind the canines towards the central incisors. They are distinguished by a prismatic shape and a convex crown. On the chewing surface there are 2 tubercles, between which there is a groove. Premolars differ from each other by their roots. In the first it is flat and bifurcated, in the second it is cone-shaped with a larger buccal surface. Second larger than the first, the depression in the enamel is shaped like a horseshoe.
- Molars– large molars (from 4 to 6 on each arch, usually the same as the number of small molars). From front to back they decrease in size due to the structure of the jaw. The first tooth is the largest - rectangular in shape with four tubercles and three roots. When the jaw closes, the molars close and serve as stoppers, so they are subject to great changes. They bear a colossal burden. “Wisdom teeth” are the outermost molars in the dentition.
The arrangement of teeth on the plates is indicated by a special generally accepted diagram. Dental formula consists of numbers indicating teeth - incisors (2), canines (2), premolars (2), molars (3) on each side of one plate. It turns out 32 elements.
The structure of the teeth of the same name on the upper and lower jaw of a person has differences.
Bottom "players"
On your upper jaw The following teeth can be found:
- Center incisors (1)– chisel-shaped teeth with a dense crown and one cone-shaped root. On the outside, the cutting edge is slightly beveled.
- Side cutters (2)– chisel-shaped teeth with three tubercles on the cutting surface. Upper third rhizomes are deflected back.
- Fangs (3)- similar to animal teeth due to pointed edges and a convex crown with only one cusp.
- I-th radical small (4)– a prismatic tooth with convex lingual and buccal surfaces. It has two tubercles of unequal sizes - the buccal one is larger, and the flattened root has a double shape.
- II root small (5)– differs from the first one in a large area on the cheek side and a cone-shaped compressed rhizome.
- 1st molar (6) is a large rectangular molar. The chewing surface of the crown resembles a diamond. A tooth has 3 roots.
- 2nd molar (7)– differs from the previous one in its smaller size and cubic shape.
- III molar (8)- "wisdom tooth". Not everyone grows it. It differs from the second molar in having a shorter and coarser root.
Top "players"
The teeth of the lower arch have the same names, but differ in their structure:
- Incisors in the center- the smallest elements with a small flat root and three tubercles.
- Incisors from the side– larger than the previous incisors by a couple of millimeters. The teeth have a narrow crown and a flat root.
- Fangs– diamond-shaped teeth with a convexity on the tongue side. They differ from their upper counterparts in having a narrower crown and inward deviation of the root.
- 1st root small– a round-shaped tooth with a beveled chewing plane. It has two tubercles and a flattened root.
- II root small– larger than the first, distinguished by identical tubercles.
- 1st molar– a cube-shaped tooth, has 5 tubercles and 2 rhizomes.
- 2nd molar– identical to I.
- 3rd molar– characterized by a variety of tubercles.
Features of teeth
What is the fundamental difference between the front teeth and chewing teeth? Functional differences were laid down by nature.
- This determined their shape and structure. As mentioned above, they are distinguished by a pointed crown and a single flat rhizome.
- Molars and premolars (lateral teeth) are needed for chewing food, hence the name “chewable”. They account for huge pressure, so they have several strong roots (up to 5 pieces) and a large chewing area.
One more feature side elements– high exposure. After all, food residues accumulate on their surface, which are difficult to remove with a toothbrush.
In addition, this area is difficult to see with ordinary eyes, so it is easy to miss the first signs of damage. It is these teeth that are most often subject to extraction and implantation.
Wisdom comes with pain
The most “sick” tooth- This is a wisdom tooth. It's a shame that it doesn't bring any benefit; its functions have long since sunk into oblivion. And lucky are those for whom it remains in its infancy and does not strive to grow.
The anatomical structure of the third molar is no different from other teeth. It simply has a shortened trunk and several tubercles.
All a person should have four “wise” teeth– 2 on each arc.
But “wise” teeth erupt later than others - in the period from 17 to 25 years. In rare cases, the process is delayed until old age. The older the individual, the more painful it will be for him.
These teeth may only seem half(semi impacted teeth) or remain undetected (impacted teeth). The reason for this harmfulness is the structure of the jaw of today's man. “Wise” teeth simply do not have enough space.
Refined diet and big size brain, the jaw apparatus was corrected.
Third molars have lost their functionality. Scientists still don't have an answer why they continue to grow.
Pain during the eruption of the third molar is felt due to its overcoming mechanical impact, because the jaw has already formed. Growth can be accompanied by various complications.
It happens that it lies horizontally, comes into contact with the nerve, puts pressure on the “neighbor”, provoking its destruction. If the third molar is pushing against the tongue or cheek, inflammation and injury cannot be avoided.
Another unpleasant diagnosis is pericoronitis. A “wise” tooth can erupt for years, and the mucous membrane suffers because of this.
Arises chronic inflammation, the gums become dense.
As a result, it appears slimy hood, which provokes purulent processes. This problem can only be solved by a dentist through surgical intervention.
Many people think about having a useless and painful wisdom tooth. If it has grown correctly and does not cause any discomfort, it is better to leave it alone. Sometimes the dentist recommends removing the second molar so that the third molar can be placed in its place.
If the wisdom tooth is very painful, then it is better to remove it, there's no need to delay this. Over the years, it settles more and more tightly in the gum; this, when removed, can cause some problems.
Curious facts
What else do we know about teeth besides the fact that they need to be brushed?
- Twins and twins also duplicate their dental “composition”. If one is missing a specific tooth, then the other is missing it too.
- Right-handed people work more often right side jaws, left-handed - respectively.
- The jaws are designed to huge load. The maximum chewing muscle force approaches 390 kg. Not every tooth can do it. If you chew nuts, you create a pressure of 100 kg.
- Elephants change teeth 6 times. Science knows of a case where a 100-year-old man's teeth changed for the second time.
- The enamel on teeth is considered the hardest tissue, which is reproduced by the human body.
- The tooth can be stored for a long time even with temperature conditions over 1000 degrees.
- 99% of calcium reserves are found in human teeth.
- Science has proven that strong teeth are a sign of good memory.
- The most expensive tooth belongs to the scientist Newton, it was sold in the 19th century for 3.3 thousand dollars. The buyer of aristocratic origin decorated the ring with it.
- Legend has it that Buddha had 40 teeth, and Adam had 30.
- Neanderthals did not have tooth decay because they ate healthy food.
- Some babies are born with a prenatal tooth in the lower jaw (1 in 2,000 cases).
- Each row of teeth is unique like fingerprints.
By mistake we don't count teeth important body. But this is a complex and fragile system. Each tooth has its own characteristic structure and performs a specific function.
A person's bite changes only once, so we must take good care of your teeth from the first days of life. Nature did not give us a chance for a second healthy jaw.
How more facts We know teeth, the more interesting they are to clean and easier to care for.
