Schedule for replacing baby teeth with permanent ones. Changing baby teeth for permanent ones in children: timing and scheme. The procedure for changing baby teeth to molars

Around the age of five, the baby's teeth begin to gradually move apart. This is how the maxillofacial apparatus is prepared for their replacement. If the spaces between the teeth do not increase, be sure to show the child to a specialist, as due to lack of space they may begin to grow incorrectly.

Why do baby teeth fall out?

When do baby teeth replace permanent teeth?

An interesting thing happens before the molars appear. physiological process: the roots of baby teeth dissolve on their own, which is why they begin to loosen and fall out. The rudiments of the molars are located between the roots of the milk teeth, which is why the resorption process begins from the place where the root is adjacent to the rudiment of the permanent tooth.

The resorption process begins from the top of the root, gradually moving towards its base. The moment it approaches the neck, it falls out.

The baby grows 20 baby teeth. An adult may have from 28 to 32 in his mouth. All milk deposits, without exception, fall out. By the age of 14, the child should be completely replaced by indigenous ones.

Shift order

Simultaneously with the loss of milk teeth, molars erupt. These two processes are closely interrelated. They appear in the same order in which they fall out: first the incisors change, followed by the first and second premolars, and then the turn comes to the canines.

The first molars grow long before teeth change; they immediately become permanent.
Second molars grow in places that appear as the jaw grows.
For many people, the third molars (also called “wisdom teeth”) do not grow at all, or they erupt quite problematically.

When do babies lose their baby teeth? They begin to loosen by the age of five.

Approximate drop order:

Several factors may influence the order in which the shift will take place:

Duration of breastfeeding.
Baby's genotype.
Infectious diseases suffered by the baby.
The course of the mother’s pregnancy, the diseases she suffered.

The (approximate) dates for the appearance of permanent teeth are shown in the table:

Each baby loses them differently: some later, some earlier. Hair loss between 4 and 8 years is normal. The order itself is important here.

In pediatric dentistry there is the concept of “spatial balance”. It is the milk teeth that determine the location where the permanent teeth will be located. In addition, baby teeth influence the spatial arrangement of molars in oral cavity.

What happens if baby teeth fall out earlier than expected?

The photo shows the age of teeth appearance

deadline?

The reasons for early loss can be very different:

Abnormally deep bite.
Injuries.
Pressure from adjacent teeth.
Tumors.
Forced tooth extraction.

Early loss disrupts the spatial balance in the oral cavity: neighboring teeth gradually begin to move, taking up free space. Therefore, it becomes difficult for permanent ones to appear normally and they may grow unevenly.

If this happens, the help of an orthodontist is needed, who will install a special “space holder” in the baby’s mouth. This device allows you to hold space for a permanent tooth.

Reasons for late eruption

The change directly depends on the timing of their appearance in the child. The delay may be caused by a number of factors:

Rickets.
Chronic infectious diseases.
Heredity.
Chronic dyspepsia.
Phenylketonuria.

Important : If by the age of 8 the child’s baby teeth have not begun to fall out and become loose, it is necessary to consult a specialist. This may indicate that the tooth buds have not formed or have died.

How long does the shedding period last? From the moment the first one falls out to the time when the last ones fall out, it usually takes from 5 to 8 years. The timing depends on several factors:

Genetic predisposition.
The quality of the water your baby drinks.
Baby's diet.

What problems might arise?

Another visual diagram of teething

The change of baby teeth is a normal physiological process that usually goes well, but sometimes some problems may arise:

Discomfort and pain.
"Shark" teeth.

During the resorption of the roots of the milk teeth, they are pushed out by the permanent ones, as a result of which the milk teeth fall out. It is rare, but it happens that this process fails: permanent tooth grows even before milk falls out. Sometimes a whole row of them can even grow. They are also called “shark teeth”, because sharks have teeth that grow in several rows.

Practice shows that “shark” teeth do not affect the condition of molars in the future. The milky one falls out, and the permanent one moves over time, taking its place.

The milky one has fallen out, but no permanent one is growing in its place. This can happen for several reasons:

delayed eruption (retention). It can be partial (when the crown has already erupted, and the lower part is under the gum) and complete (when the tooth has already formed, but is still under the gum).
adentia (absence of a tooth) is a consequence of the death of its rudiment. Complete edentia is a huge rarity; this can happen if serious disturbances occur during intrauterine development.

At the age of 6 months, the child's first teeth appear. Their role is temporary. When the baby grows up, they fall out and permanent, radical ones begin to grow.

Changing baby teeth is natural process. It does not require medical intervention.

Why do baby teeth grow at all?

Many parents are very interested in the problem children's teeth. What are they for, how many of them should grow normally. The order of cutting.
The first teeth appear in early age. The child is usually not even a year old. This is a painful process, often excruciating for the baby. But it is inevitable.
The importance of baby teeth has been studied and proven.

Allows you to chew solid food. This allows the baby to switch from mother's milk to regular food. Acquiring chewing skills
Participate in the pronunciation of certain sounds
Contribute to proper development skull bones. A bite is forming
Beautiful mouth view

Let's delve into the terms: the correct names of baby teeth

Each tooth has its own name. Dentists also assign it their serial number. The countdown starts from the center of the jaw.
When describing the cutting order, they rely specifically on colloquial terms.
This makes it clearer to the baby’s parents.

The lower central incisors erupt first. This occurs between 6 and 9 months of age.
Following them are the upper central incisors. Teething age 7-10 months
The upper and lower incisors, located next to the central ones, appear when the child turns one year old
Then come the first molars (chewing)
The most problematic ones are the fangs (eye ones). Their turn comes when the baby turns 1.5-2 years old
The last to appear are the posterior molars.

By 30 months, your baby should have all 20 teeth.

Important! If a child is 4 years old and has some teeth missing, consultation with a specialist is necessary. Pathology may develop.

Features of baby teeth

Externally, baby teeth are not much different from molars. However, there is a difference, and it is significant. One of the main differences between baby teeth is their fragility.
Their features include:

They are covered with a thinner layer of enamel.
Reduced crown size
Enlarged pulp
Have a milky tint
Easily affected by caries
There are only 20 baby teeth. Indigenous 32

Which baby teeth fall out first?

When a baby reaches a certain age, natural mechanisms for changing temporary teeth to permanent ones are launched. Active growth of molars begins. At the same time, the process of resorption (dissolution of roots) occurs. The tooth begins to wobble and falls out. In its place, a small wound forms in the gum, which may bleed slightly.
After some time, the empty space will be filled with a new, already permanent tooth. This is a natural process that normally does not require medical intervention. For peace of mind, parents should understand which baby teeth fall out first and monitor these processes.
First of all, the incisors are replaced: upper and lower. It is their loss that begins the process of changing teeth.

Until what age can baby teeth fall out?

The process of changing teeth lasts more than one year. Root resorption begins at the age of 5 years and lasts about 24 months. Accordingly, the first milk teeth fall out when the child turns 6 years old. Resorption of the roots of the upper and lower large molars begins when baby is coming to school and lasts 3 years. Accordingly, they will change when the child turns 11-13 years old.

Fact! It has been established that those baby teeth that have been treated fall out much more slowly.

All time periods are written approximately, based on average statistical data. Any slight deviation from what is written is normal. You should consult a doctor if you experience severe delay or early tooth growth.

The procedure for changing baby teeth to molars

The procedure for changing baby teeth is similar to their eruption.

Important: The first molars begin to grow even before the incisors begin to fall out.

The first molars begin to grow when the child is 6 years old.
In the period from 6 to 8 years, the child's incisors should completely change. Moreover, the central incisors grow first, and then the lateral incisors.
From 7 to 10 years it is the turn of the premolars. At 9-11 – fangs are replaced. Then the second molars grow. This process should be completely completed by age 13.
Special mention should be made of wisdom teeth. Their growth occurs at a much faster rate late period. They begin to appear no earlier than 17 years of age.

Interesting: Wisdom teeth may never grow back.

The order in which molars erupt is influenced by many factors:

The period during which breastfeeding continued
Genetically programmed
Infectious diseases
Complications during pregnancy

Are all children's milk teeth replaced by permanent ones?

There is a misconception that all of a baby's first teeth are baby teeth. And over time they change to radical ones. This is wrong.
The child has only 20 teeth. But in an adult jaw there are 32 teeth. A child’s first permanent teeth begin to grow at the age of 4 years. Dentists call them “sixes” or molars. They grow behind baby teeth and do not interfere with their replacement. Then the second molars (“sevens”) grow.
By the time the baby teeth change, the child should have 28 of them.
The last 4 teeth (“eights”) are wisdom teeth. They grow into adulthood, and in some they remain embryos.

Signs of imminent replacement of milk teeth with permanent ones

Change baby teeth permanent symptoms begin in children at approximately five and a half years of age. Sometimes it happens a little earlier or later. The child’s maxillofacial apparatus is preparing for the replacement of baby teeth. You may notice that the spaces between baby teeth have become larger - this means that the child’s jaw is growing, because more space is needed for permanent teeth. If the gaps do not increase, permanent teeth may begin to grow crooked, so be sure to take your baby to the doctor.

Loss of baby teeth

The process of replacing baby teeth with permanent ones is interesting and not quite complicated. Some time before the fall baby tooth, its root gradually dissolves, the tooth begins to wobble. As the root of a baby tooth is reabsorbed, it becomes more and more unstable until it falls out. Simultaneously with resorption, the permanent tooth slowly grows. Sometimes baby teeth fall out on their own; often children loosen them and pull them out on their own. The root of the new tooth is not yet fully formed. This will take at least two to three years.

In order for the roots of permanent teeth to form strong, and for the health of the teeth themselves, a sufficient amount of calcium should be introduced into the child’s diet. But how to calculate the correct required dose? To make sure you don’t make a mistake, buy Biocalcium for children produced by Tiens for your baby. This is a one hundred percent natural drug that will completely provide the child with the necessary amount of calcium. Biocalcium from Tiens is absorbed by the child's body by ninety percent.

Sequence of teeth changes

The timing of teeth change is very individual, but the sequence of this process is always the same. The first permanent teeth you will find in your baby's mouth are molars - the sixth teeth in a row, if you count from the middle of the jaw. The place for these teeth will appear when the jaw grows, and the appearance of sixth molars is not associated with the loss of baby teeth.

Next, the replacement of baby teeth with permanent ones occurs according to the same scenario in which baby teeth appeared. The incisors begin to wobble and change - first two on the top and lower jaw, and then two more. After this, the premolars are replaced - the teeth that are located behind the fangs. The replacement of the first premolars occurs between the ages of nine and eleven years, then the second premolars must change until the age of twelve. Until the age of thirteen, the canines are replaced, followed by the second molars at the age of fourteen (they also grow in the empty spaces formed as a result of jaw growth). The last to appear are the third molars, the so-called wisdom teeth. This happens after fifteen years. By the way, an increasing number of young people never get these teeth. In fact, they are no longer needed modern people, and nature solves this issue.

When is a dentist needed?

Usually, replacing baby teeth with permanent ones does not require any intervention from dentists. It happens quite painlessly. But there are cases when the permanent tooth is already visible, but the milk tooth is not even loose. This situation threatens the child with the fact that the permanent tooth will grow crooked and will subsequently have to be fitted with braces to straighten it. Therefore, if you notice anything like this in your baby, go to the dentist immediately. The milk tooth will be removed, and then the process will proceed as expected.

Tiensmed.ru) reminds us of one extremely important point. In order for your baby's teeth to grow strong and healthy, teach him to brush his teeth daily. When your baby is a year or a year and a half old, buy a special toothbrush for him and toothpaste. There are very wide choose similar products from different companies. The requirements for the brush are as follows: it must be the right size for the child, the bristles must be soft. Well, you need to choose pasta according to the age of the baby. Children always enjoy imitating their parents' brushing their teeth. Remember to visit your pediatric dentist periodically. For the normal replacement of milk teeth with permanent ones, it is necessary to eliminate foci of infection in the child’s mouth -

The process of changing baby teeth in a child always worries parents. The change takes quite a long time, often accompanied by inflammatory processes, painful sensations, permanent teeth can grow crooked. To make parents feel calmer, a special table has been created that indicates the growth pattern of molars and the age at which the baby will have them.

Dairy products are placed on 4-6 weeks of embryogenesis ( intrauterine development). But constants are formed much later - during the first months of children’s lives. That is why in case artificial feeding your child's diet must contain a large number of calcium. It is calcium that forms the enamel and the entire dental organ.

The appearance of the first teeth classically occurs between six months and a year. The order in which a child's teeth appear is as follows: first the central incisors will appear from below, then from above, then the lower and upper ones on the sides, followed by the first molars, followed by the canines, and last in order - the second molars. There is a term “dental formula” - the normal number of teeth in children: two incisors, two molars, a canine, and no premolars. We multiply these data by four and get the number of non-permanent teeth that is normal.

The photo shows a diagram of the appearance of teeth:

Don’t worry if the order or timing of the eruption of the first teeth is disrupted; the process occurs very individually in children. The most important thing to consider is that the first ones take up to a year to erupt, otherwise visit the dentist.

Primary teeth in children are susceptible to caries; it is imperative to monitor the health of the teeth, because an infection of a baby tooth can lead to damage to a permanent one. The reason lies in the fact that the permanent teeth in the jaw are located too close to the root of the temporary ones. If you notice dark spots on your child's enamel, rush to the doctor.

Teeth replacement

The process of replacing teeth usually begins when the child first goes to school—the first teeth fall out at the age of six or seven years. The order of replacement almost completely coincides with the order of eruption, with the only exception being the fangs - they are replaced later than all the others, at the age of about thirteen years. Before they fall out, the first molars grow in - but no replacement occurs, the jaw just grows and the teeth grow in their own in the right place. Behind the fangs, second molars will grow, and last of all, “wisdom teeth”, third molars, will appear - usually between the ages of 18 and 25 years.

Despite the frightening appearance of the process, it is quite physiological, and children do not experience pain. But it is necessary to monitor the condition of the oral cavity, because if inflammation develops during the change of teeth, the infection should be treated.

There is no need to try to help by pulling out a child’s baby teeth. The tooth falls out on its own from the moment the mechanism that dissolves the roots of the tooth is activated in the body in children. It is worth contacting the dentist only when the permanent one has already begun to grow, and the temporary one has not yet fallen out, since the temporary one will interfere with the correct growth of the root one.

Minor bleeding occurs from tooth loss. Previously, it was recommended to rinse your mouth with a solution of hydrogen peroxide, but capillary bleeding in itself is insignificant. If desired, you should rinse your mouth with a solution of soda with a drop of iodine to prevent infection of the wound.

Teeth grow unevenly - what to do?

It happens that children's teeth grow incorrectly. First of all, it is worth understanding the reason for such a violation. The following options exist:

The child has habits of thumb sucking, chewing pens and pencils.
The child's jaw grows more slowly than the replacement process occurs.

In the first case, wean your precious child from such habits. Otherwise it will form malocclusion, and the smile will subsequently look unaesthetic.

In the absence bad habits, it's more about bone growth facial skull It is recommended to consult a dentist, but after changing the entire dentition, in order to correct the bite and make the smile beautiful. There are various correction systems that any qualified doctor will familiarize you with.

Care

In addition to standard hygiene procedures(this means brushing the teeth and mouth), when replacing teeth in children, you should Special attention pay attention to your diet. Include in children's diet dairy products, cheese, that is, everything enriched with calcium. It is advisable to strengthen the diet with a complex of minerals and vitamins, thanks to which the teeth will be provided with strong enamel.

During hygienic cleaning Do not be overzealous; the child should not injure his gums. Otherwise it may develop inflammatory process, leading to painful sensations and difficulties resulting from the eruption of permanent teeth.

Now you know the mechanism for replacing baby teeth. If all recommendations are followed and proper care Children grow straight and beautiful molars, and their smile will always delight you.

The moment of changing milk teeth to permanent ones is enough difficult stage both for the child and for the parents. Teeth wobble, fall out, and it can be painful and uncomfortable for a child to bite. Then they grow, but they are not always even and white, there may be gaps between the teeth, and plaque also appears, which over time can turn into tartar. How to behave correctly during the period when children change teeth, and what parents should pay attention to.

The replacement of baby teeth with permanent teeth begins at 6 years of age. But these are average data. Sometimes the first baby tooth It can fall out at 5 or 7 years.

Loss of baby teeth usually occurs symmetrically on the right and left, first on the lower jaw (except for the second molars). Temporary teeth with treated roots or damaged pulp fall out faster than intact teeth (healthy ones, not damaged by any diseases.). In girls this process occurs faster than in boys.

Changing baby teeth:

Central incisors - 6-7 years;
lateral - 7-8 years;
fangs - 10-12;
first molars - 9-11;
second molars - 10-12.

Factors on which the replacement of baby teeth with permanent ones depends:

heredity,
nutrition,
hygiene,

the state of the child’s body as a whole,
chewing mode (this means how intensely the child chews, what consistency of food predominates - hard, hard or, conversely, ground, soft).

The eruption of permanent teeth also depends on the timing of the eruption of baby teeth.

The timing of baby tooth loss is directly dependent on:

Growth rate of permanent teeth (their vertical growth),
intensity of physical development,
condition of the pulp (neurovascular bundle),
condition of the temporary tooth.
Each baby tooth has its own period of formation and development (1.5-2.5 years), stabilization (2.5-3) and resorption (2-3 years). After these periods, the teeth fall out.

Is there a scheme for replacing baby teeth with permanent ones?

Indeed, there is a scheme for changing baby teeth. The lower primary central incisors are the first to fall out, most often occurring at the age of 6 years. But sometimes (in about 50% of cases) the permanent, CHEWING teeth erupt first.
Permanent “sixth” teeth have no analogues to baby teeth, so their appearance is unnoticed by parents.
And the dentist discovers a “surprise” during the examination. But it is these permanent teeth that are most often the first permanent teeth to suffer from caries. And it is these teeth that can be protected with sealing.

Parents and children must be told about this and much more at regular preventive examinations. In addition, you can find out more information on the clinic’s website md-clinica.com.ua/service/pediatrician

Let's return to the diagram: there is one rule - in what order the milk teeth erupted, in that order they will fall out. Very rarely does this scheme fail. But in no case should this frighten parents - this is not a pathology, but a feature of the little person’s body. Each scheme and deadline should be approached strictly individually.
Very often, parents do not even suspect that the first permanent teeth have already appeared in the baby’s mouth. And they are very important in the formation and subsequent development of occlusion in children.
Of course, there is a certain pattern in the replacement of milk teeth with permanent teeth. They erupt in a certain order and at a certain time, and not when they want it.
The molars are the first to grow - these are the so-called “sixth” teeth. Space for molars appears already during the development and growth of the jaw.
Then the process of replacing baby teeth occurs in the same way as baby teeth appeared. The incisors wobble and change. First, two on both jaws, then two on the other. Then there is a change of premolars - the teeth located behind the fangs. Typically, the first premolars change at 9-11 years of age, and before the age of 12, the second premolars change. As a rule, by the age of 13, a child’s fangs also change. The second molars grow behind them. And finally, the last permanent teeth are the third molars, or wisdom teeth.

Growth rate of molars

There is no known growth rate for permanent teeth. But if a permanent tooth does not erupt within 3-5 months, it may simply not have enough space in the jaw; the jaw is small and narrow. In this case, you should contact pediatric dentist, may be needed orthodontic treatment(i.e., bite correction).
The rate of tooth growth varies from person to person. It can last from several months to a year.
If this issue begins to bother you, you can undergo a special X-ray examination, with the help of which the doctor will see the time of eruption, as well as whether all the rudiments of permanent teeth are present.
