When do milk teeth begin to change. Change of milk teeth in children - terms

What teeth change in children and in what order? It is considered erroneous that the entire dentition changes in a child. During a person's life, only 20 teeth change. Initially, 8–12 erupt as permanent. "Sixes" - the first molars in children. They appear before the prolapse of the central milk incisors.

Milk teeth fall out: when and in what order?

Deadlines may vary. They depend on individual characteristics of development. This process is long and most often painless, asymptomatic. The milk root gradually resolves, then it begins to stagger and falls out. What do you need to pay attention to?

Dentists recommend loosening, swinging milk teeth during their change. Children can perform this procedure on their own.
A milk tooth can sit tight and interfere with the growth of a permanent one. It is shown to consult a dentist and remove the interference. If this is not done in a timely manner, the permanent may grow crooked or in the second row.
After treatment, milk roots dissolve slowly. More often than not, they have to be removed.
If the wound bleeds after falling out, let the child hold a tampon, a piece of sterile bandage and hold for several minutes. It is advisable not to eat for 2 hours after a tooth falls out or is removed. Let the child refrain from hot, cold, sour, salty foods. Do not allow to actively rinse the wound! A cork is formed in the well, which protects against the ingress of microbes.
It happens early. What can this lead to? The free space in the jaw leads to the displacement of the remaining milk teeth, then the permanent ones will begin to grow crooked in due time. Here you need to consult a pediatric orthodontist.
The pattern of loss of milk teeth in children is always the same. Usually, they drop out in the same sequence. In most cases, the process of prolapse begins with the lower jaw.

Baby teeth	Beginning of root resorption, age	Duration	prolapse, age
Upper and lower central incisors	from 5 years old	2 years	5–7 years
Upper and lower lateral incisors	from 6 years old	2 years	7–8 years
Molars small (upper and lower)	from 7 years old	3 years	8–10 years
Fangs upper and lower	from 8 years old	3 years	9–11 years old
Molars large (upper and lower)	from 7 years old	3 years	11–13 years old

Comparative analysis of milk and permanent dentition

Permanent teeth: features of eruption

Eruption order	Name	Age in years
1	Lower central incisors 1st molars, upper and lower	6–7
2	Upper central incisors, lower lateral incisors	7–8
3	Upper lateral incisors	8–9
4	lower fangs	9–10
5	1st premolars upper	10–11
6	1st premolars lower, 2nd premolars upper	10–12
7	Canines upper, 2nd premolars lower	11–12
8	2nd molars lower	11–13
9	2nd molars upper	12–13
10	Third molars upper and lower	17–21

The eruption of molars in children also occurs according to the scheme. What do you need to pay attention to?

Vulnerability. In a child, permanent teeth have a larger pulp than in an adult. At the same time, hard tissues are only being formed, therefore they are easily exposed to external influences. This is especially true for the "sixes". They suffer the most. Elementary precautions: the exclusion of too hard and viscous food. This includes nuts, candy, toffee.
Period. Between the loss of a temporary tooth and the growth of a permanent one, 4-6 months can pass. This is the norm. If six months have passed, and a permanent one does not appear in the hole, you should definitely contact a specialist. Perhaps the tooth does not have enough room for eruption.
Growth rate. The front incisors grow rapidly. Much slower - fangs. The growth of premolars and molars can be difficult and lengthy. The reason is the large eruption area.
Terms of eruption of permanent teeth in children: violations. Terms depend on heredity, developmental features, past infections. The delay in eruption can be explained by a physiological reason: the tooth germs have not yet formed. There is nothing dangerous in this. This is an individual feature. It is also possible that the tooth is not properly positioned in the bone tissue. These and other abnormalities can be detected by a doctor with the help of X-ray diagnostics. What can violations lead to? To various defects: location outside the arch of the dentition, malocclusion, inclination, rotation, etc.
Molar teeth in children: temperature. Sometimes children may complain of soreness, swelling, itching of the gums, and general fatigue. Most often, the temperature rises when molars are cut. The reason - in a large area of inflammation of the gums. The pain syndrome in this case also intensifies. If the molars exceed 38 ° C, it is better to give the child
1. The need for phosphorus. Not without fish! For cooking, use low-fat varieties of sea fish.
2. More calcium. A variety and abundance of dairy products is desirable.
3. Vegetables and fruits. First, it is a source of essential vitamins. Secondly, solid food accelerates the process of loosening milk teeth. It is important to load the jaw during this period.
4. Limitation of sweets. A deplorable item for children. However, it is sweet foods that lead to the formation of lactic acid, which negatively affects enamel and hard tissue.
Changing teeth in children is an additional burden on the body. It will be useful to take a multivitamin complex.

Loss and teething is a self-regulating process in the human body. Bone tissues, endocrine and nervous systems are actively involved in it. Here, orthodontic problems are possible, which, with a variety of modern methods, are successfully corrected.

This article talks in detail about children's milk teeth, about typical problems and methods for solving them.

In all people, teeth are divided into three types, each of which performs its function:

Incisors - responsible for biting off food;
Fangs - hold and tear off food;
Molars and premolars - grind food.

- These are the first teeth that appear between the ages of 8 months and 3 years. As a rule, in order to determine how many teeth a child should have, they take away from the age in months - 4. That is, at 6 months there should be two teeth, etc.

The milk tooth consists of the same parts as the permanent ones:

Crown- the visible part of the tooth, located above the gum. The main difference is that crowns are smaller than molars. The crowns are wider and lower than those of the indigenous ones. Since crowns have a lower degree of mineralization, respectively, milk teeth are more susceptible to caries.
Neck The part of a tooth located between the crown and the root. In temporary teeth, it is much narrower.
Root- with the help of it, the tooth is held in the recess of the gums, called the alveolus. Milk teeth have roots, contrary to popular myth. The number of roots in different types of teeth is different. The roots of milk teeth are thinner and shorter. Before replacement, the roots of milk teeth dissolve. This article contains the answer to the question,.
Enamel- the hardest tissue of the body, covers the crown, in temporary teeth it is about two times less than in molars.
Dentine- porous tissue, located directly under the enamel.
Pulp- connective tissue, which is located in the center of the tooth, it contains blood vessels and nerve endings. In milk teeth, the pulp occupies more space than in molars. Since hard tissues are thinner, when caries or other infections are affected, milk teeth are destroyed faster.

Temporary teeth are whiter in color. And on the incisors, the tubercles are less noticeably developed. The rudiments of the molars are located under the milk teeth, which are landmarks for them.

How is the change of teeth

Replacement of temporary teeth with permanent ones occurs gradually and begins with the formation of gaps between the teeth. The jaw increases in size and the distance between the crowns increases. In fact, at the moment when the child has the third molars, this is about 4 years old, preparations for the change of teeth begin.
In general, a person has 8-12 teeth, which do not change, but immediately cut through as constants. The change occurs within 7-9 years. The body prepares itself for replacement. The roots of temporary teeth gradually dissolve, and therefore the tooth begins to stagger, since nothing holds it anymore, and when only the crown remains, it falls out altogether.
Teeth usually change in sequence in which they are cut. The main thing for parents is not to panic, the child does not experience any pain. Deterioration of well-being is a very rare case, and this happens due to inflammation of the gums.

How many milk teeth do children have

Milk teeth begin to appear at 6-8 months. This is because, in addition to milk, more solid food appears in the diet. The incisors appear first, first the central ones, then the lateral ones. But the formation of teeth occurs as early as the 5th month of pregnancy, and by the ninth month there are already the rudiments of all teeth, including permanent ones.

By the age of two, the baby has fangs, the first molars a little earlier by 1.5 years. The second molars are the last to erupt, by about 2.5 years.

By the age of 2, a child has 20 milk teeth, and not 32 as in adults:

Incisors - 4 above and 4 below;
Fangs - 2 on each jaw;
Molars - 8 pieces.

Do you want white and healthy teeth?

Even with careful care of the teeth, spots appear on them over time, they darken, turn yellow.

In addition, the enamel becomes thinner and the teeth become sensitive to cold, hot, sweet foods or drinks.

In such cases, our readers recommend using the latest tool - Denta Seal toothpaste with a filling effect..

It has the following properties:

Evens out damage and fills microcracks on the enamel surface
Effectively removes plaque and prevents the formation of caries
Restores natural whiteness, smoothness and shine to teeth

Procedure for changing teeth

Teeth begin to change at about 6 years old, but each child has their own timing, so you should not panic ahead of time. Teeth begin to change after the growth of the molars, they appear when there is enough space in the jaw.

Here are the approximate timing of the change of all teeth:

All teeth can change in 5-8 years, it depends on many factors:

Food;
Genotype;
Gender of the child, girls usually change earlier than boys.

If the shift sequence is different, this is not a cause for concern. And already in adulthood, “wisdom teeth” erupt.

A situation may occur in which the roots of milk teeth do not dissolve, and then they do not fall out, but remain even in their adult state. This usually happens if there is no rudiment of permanent teeth under temporary teeth, since it is they that provoke the beginning of a change in the dentition.

What if the teeth fell out prematurely?

There are several reasons why a baby tooth may fall out prematurely.

Before the due date, this is before the child reaches 5 years of age:

An injury in which a tooth can simply be knocked out.
Tumor.
Pressure from adjacent teeth.
Incorrect bite structure.
Extraction of a tooth as indicated by a dentist (if it is completely destroyed and cannot be restored).
Infections before 6 years of age.
Pathologies during childbearing.
The child himself can prematurely loosen the tooth

If the baby tooth falls out earlier, it threatens that the neighboring teeth will move towards it, and as a result, this will lead to serious bite defects. Often the cause can be caries, which is triggered because of the belief that care is not required for temporary teeth.

It is worth paying attention: if a molar appears in place of a fallen tooth, then this is the norm, you should not worry and early loss is not a deviation. But, if nothing appears in the place of the fallen tooth, you should contact your dentist.

It is even possible to assign special devices to save space for the molar. In general, it is believed that the later the change of teeth begins, the better. But this process should begin no later than 8 years, otherwise be sure to contact a specialist.

Incorrect bite spoils the appearance of a smile, leads to tooth decay and caries. Not everyone has the opportunity to put braces. At home, you can use a mouthguard, it does not require grinding of teeth, does not harm enamel and gums.

Thanks to the universal size, it is suitable for any age. The cap is made of durable material - medical polyurethane, so it does not injure the gums and teeth while wearing. I recommend.

Dental care during shift

If the teeth are temporary, this does not mean that they do not need care. A child should be able to use a brush from early childhood, for this you need to purchase a brush with soft bristles. Teeth should be brushed under the supervision of an adult, so as not to injure the gums.

Milk teeth are more susceptible to caries and decay faster, so you need to monitor oral hygiene! The paste should be chosen for children, it has a special composition and does not have coarse abrasive substances that can damage thin enamel.

The main rules for caring for your teeth during a shift:

Rinse your mouth, after each meal, you can simply clean water, you can use special decoctions (for example, chamomile).
Taking vitamins and minerals.
Carefully monitor the growth of teeth and their condition, if necessary, contact the dentist.
Since the fissures (natural cavities between the tubercles of the teeth) are deeper in milk teeth, some experts advise filling them with a special compound so that food particles do not get in and caries can be avoided. Such a procedure is called.
Provide proper nutrition, namely:
- Vitamin D (eggs, butter, milk).
- Calcium (milk and dairy products).
- Phosphorus (cheese and seafood).
- Eliminate sweets or severely limit.
- Give solid food, it promotes the resorption of the roots.

When baby teeth fall out

Regarding the age of tooth loss, it is worth noting that the figures are very approximate. After the appearance at the age of 4 molars, which are immediately root, preparation for the change of teeth begins. At about 6 years of age, the incisors change, usually the lower ones first. The whole process of change ends by the age of 13-14.

But the body of each child is individual, and in addition to the early one, a later loss may also occur. If the child is over 16 years old, and the teeth have not yet fallen out, this is a reason to contact the dentist.

The main reasons for late fallout are:

Eating disorder.
chronic infections.
Frequent stress.
Lack of trace elements in the body.
Failures during the mother's pregnancy, as a result of which the rudiments of molars did not appear.
Dyspepsia.

What teeth are changing

An adult has 32 teeth in a set:

Incisors - 4 on each jaw.
Fangs - 2 at the top and 2 at the bottom.
Molars - 6 on top and bottom.
Premolars - 4 pairs.

Sometimes, if “wisdom teeth” do not erupt, a person has only 28 teeth. Of this set, only 20 teeth change, the rest immediately appear as the main ones. Change incisors, canines, and 4 pairs of molars.

When Medical Assistance May Be Needed

The process of changing teeth is natural and usually goes without problems. Parents should show their child to the dentist every six months to avoid problems in the future. If caries is noticed at the stage of the beginning of enamel destruction, then the tooth will not have to be removed, and this is very important. Early removal of a temporary tooth can lead to problems with molars.

When you need the help of a dentist or pediatrician:

If the gums are swollen and itchy.
When a milk tooth interferes with an already erupted molar (if you do not consult a dentist, a permanent tooth can grow crookedly).
If the milk ones fell out, but the root ones did not appear.
If the milk tooth has darkened, crumbles or has spots on it.
After falling out, the wound bleeds for more than 10-15 minutes, there may be problems with blood clotting.
Temperature, feeling unwell during a tooth change.
If a loose tooth does not fall out, but it interferes greatly, for example, there is.

After a tooth has fallen out, you need to give the child a cotton swab or a sterile piece of gauze so that he bites it. On the day when the tooth fell out, you should not give anything sour, salty, hot, and generally irritating to the gums. The first two hours, regardless of whether the dentist pulled out a tooth or he himself fell out, you can’t eat until the wound closes to avoid infection.

What if teeth grow crooked

First, let's look at the reasons.

Crooked milk teeth can be due to:

In this case, be sure to go to the dentist, if necessary, he will prescribe treatment.

If crooked teeth are already growing, it can also be corrected, for this you also need to contact a specialist in time. To align the teeth, braces, special devices made of metal or ceramics are used. The latter look prettier and less noticeable, so children are more likely to agree to wear them.

With the curvature of the teeth, it is important to go to the dentist as early as possible, if the process is delayed, then a crooked smile can remain for life.

Braces are of two types:

Removable, used up to 8 years, made of silicone. They usually dress up at night.
Fixed, for permanent wear, used at an older age.

To sum up, we will give some tips that will be useful to all parents:

Take care of your child's teeth from the moment they appear.
Visit the dentist twice a year.
Be careful with sweets, this is a direct path to caries.
Come up with a pleasant fairy tale so that the change of teeth does not cause negative emotions in the child.
Wean your baby off the bottle and pacifier as early as possible, and keep your baby biting.
Any darkening of the enamel and stains on the teeth is a reason to go to the dentist, regardless of the fact that the teeth are temporary. The health of permanents depends on their health.
Watch out for bad habits, otherwise your teeth may grow crooked.
The diet should have enough vitamins and minerals, if they are not enough, take vitamin-mineral complexes.
Remember, this is a natural process and there is nothing terrible or difficult about it.
What is a paste and a brush a child should understand from the age of two.

And then your child will delight you with a white-toothed smile!

The answer to the question at what age children's teeth change is not so easy to find, because the process of changing milk teeth to permanent teeth begins in each child in different ways, according to the individual and physiological characteristics of the body's development.

On average, the process of changing teeth in children begins at the age of 5 and ends by the age of 14, but, taking into account factors such as nutrition, the health of the child, physiological and genetic indicators, the change occurs at different times.

Factors affecting the change of teeth

Before you worry about the early or late change of teeth in a child, you should know the reasons that affect this process:

Complete nutrition of the child, a balanced diet rich in foods containing calcium, a sufficient amount of consumed cottage cheese, sour cream, milk, kefir, fermented baked milk contribute to the rapid formation of healthy teeth and bones. Accordingly, the lack of dairy products in the diet leads to a lack of calcium and vitamin D in the body and disrupts the formation of hard tissues.
Heredity. The genetic factor either has a positive effect on the growth and development of teeth, if good dynamics are observed in the genus, or leads to process disturbances if the dynamics are negative. In the second case, it is rather difficult to improve the process of growth and development, but with the help of special vitamin complexes and a balanced diet it is possible.
Features of the health of the child. In children suffering from diseases of the gastrointestinal tract, there are destructive processes of enamel and slow growth of teeth. This is due to the characteristics and side effects of certain medications, namely antibiotics. Therefore, it is necessary to take into account the peculiarities of medicines and enrich the child's diet with dairy products during the period of treatment with these drugs. Some physiological features of a child's development can slow down the growth of teeth. For example, diseases such as Down's syndrome, mental retardation, oncological diseases and other serious conditions are accompanied by slow tooth growth, enamel destruction or even its absence. With the normal development of a child, teeth are formed without defects, and their poor growth may indicate that there are hidden problems in the body.

When do milk teeth change?

The change of milk teeth to molars occurs according to the principle of pairing and begins at the age of 5 years. First, the two lower front incisors are changed. Dentists explain this by the fact that the front teeth of children are subjected to intensive work and environmental factors daily, they are cut first, and the child gnaws all objects with them. In nature, it is natural that the front incisors always receive food first and begin the process of its mechanical processing. Thus, the lower incisors erupt earlier and fall out earlier. The root front incisors climb long enough, from 4 months to six months. Both children and mothers are worried about ugly smiles, but it should be understood that the process of changing teeth is inevitable and is a sign of growing up.

After the appearance of the lower incisors, the anterior upper ones begin to change. When a permanent tooth erupts, it displaces a milk tooth from the gum, which can fall out upon contact with any surface, and even with water. The change of the first milk incisors to molars occurs at the age of 5-6 years of a child's life.

Following the anterior lower incisors, the lower lateral incisors change in pairs, which can displace milk teeth from the gums, and also grow behind the milk teeth, depending on the characteristics of the development of the child's body.

When the lower lateral incisors have erupted at least halfway, the upper lateral incisors begin to change, which appear in children by crowding out milk teeth. Lateral incisors can grow with deviations to the sides, this is their characteristic feature. Do not worry about this, because. after the change of all milk teeth to permanent ones, the row aligns itself. The change of upper and lower lateral incisors occurs at 6-8 years of a child's life.

The lower first molar changes to the root immediately after the change of the lateral incisors, at about 9-11 years. The upper and lower molars erupt in pairs, the period from eruption to full formation is from 6 to 9 months.

The change of milk fangs to permanent ones occurs from 9 to 12 years old, first the fangs of the lower jaw change, then the upper.

The second molar of the lower and upper jaw changes from 10 to 12 years.

The fangs are replaced immediately after the molars, at 10-12 years of age. With an incorrect bite of the jaw and in the case of “licking” the empty space between the teeth after the loss of milk, you can get the problem of improper formation. The tooth can move to the side, grow crooked and shift the neighboring ones.

The remaining teeth of the row change from the age of 12 after the main ones are fully formed.

Age indicators may differ from the above individually. But if there is a failure in the sequence of changing teeth, they grow crookedly or with a violation of the integrity of the enamel and shape, then in this case the child should be shown to a specialist, since it may be necessary to carry out corrective procedures by an orthodontist. An important indicator of the growth of healthy teeth is the observance of the rules of oral hygiene.

Oral care rules

Changing milk teeth to molars is not as painful as teething in babies, but it can cause a number of complications and in some cases is accompanied by pain. In order to facilitate the process of changing, first of all, the child must know how the rules of personal oral hygiene are observed. You should brush your teeth 2 times a day, in the morning and at bedtime, and rinse your mouth after each meal.

Complicate the period of changing teeth open wounds in the gums. This occurs if a child's teeth are pulled out prematurely, without waiting for their natural loss. Therefore, dentists do not recommend pulling out a milk tooth, even if it is loose. It will fall out naturally, and then there will be no wound on the gum. If, nevertheless, there are wounds in the gum, it is necessary to cure them with regular rinsing of the mouth with a weak solution of soda or herbal decoctions.

The gums do not always become inflamed during teething, but if such a process has formed in the mouth, it can be quickly cured by rinsing the mouth 2-3 times a day with decoctions of herbs (mint, chamomile, oak bark or lemon balm) or special rinses that can be purchased at the pharmacy .

If there are carious lesions on the milk tooth, they must be treated in time to prevent infection from entering the gum and transmitting caries to the indigenous ones.

Angina and stomatitis should not be allowed when the child's gums are damaged, and if the child suffers such serious diseases, they must be treated in a timely manner, otherwise complications may arise.

Milk teeth got their name from the ancient Greek physician Hippocrates, who was convinced that they are formed from mother's milk. Did you know that the change of milk teeth does not always occur? In the absence of the rudiments of permanent crowns, a person can pass with milk crowns all his life, up to old age.

When teeth should change normally, what this process depends on, what deviations can be, and how to prevent them - read in our article.

Terms of change of milk teeth

The process begins at age six or seven, but some children lose their teeth at age five or eight. If this happens much earlier or later, parents should definitely show the child to the dentist.

Factors affecting the timing:

Heredity. Very often, the change of teeth in children takes place at the same time as that of their parents in childhood.
past infections;
metabolic problems. Violation of the metabolism of substances occurs due to rickets, phenylketonuria and other diseases that affect metabolic processes;
dyspepsia - disturbances in the work of the stomach;
lack of rudiments of root molars. Similar pathologies occur even in the prenatal period due to pathologies during pregnancy.

How are milk teeth replaced by permanent teeth?

When milk teeth change, their roots begin to gradually dissolve, giving way to new ones.

How is this mechanism started?

All the rudiments of permanent teeth are separated from the milk roots by a bone plate. When the molar rudiment begins to develop and increase in size, it puts pressure on the bone plate.
During this process, osteoclasts appear - cells that dissolve the mineral component of the bone.
In parallel with the “attack” of osteoclasts from the outside, the tooth undergoes internal changes: its pulp (vascular-nervous tissue) changes and stops into granulation tissue, in which osteoclasts are also present.
Thus, milk roots from the outside and from the inside are exposed to osteoclasts and are absorbed.
Only one crown remains: it begins to wobble and soon falls off, because it simply has nothing to hold on to the jaw.

Often this process is accompanied by an increase in body temperature, general malaise. When the tooth "breaks away" from the row, there is a slight bleeding. Normally, it stops after 3-5 minutes.

The first to fall out are the central incisors - at the age of six or seven.
At seven or eight years, the turn of the lateral incisors comes.
From nine to eleven years - the first molars, from nine to twelve - the lower canines.
Later than all - from ten to twelve years - the upper canines, the first and second molars of both jaws fall out.

For most children, the process of replacing milk teeth with molars takes five or six years and lasts until the age of thirteen or fifteen.

FAQ

Do all 20 milk teeth change?

Everything must change. If some of them have not been replaced by indigenous ones, you need to see a dentist.

How to help a child with loss of milk teeth?

It is important to provide the baby with good nutrition: include foods rich in calcium, vitamin D, fluoride, fresh vegetables and fruits. It is also recommended to exclude sweets to the maximum. Great importance should be attached to oral hygiene (ideally - brushing after each meal).

When bleeding at the site of a fallen tooth, the child should be given a bite to eat with a sterile cotton or gauze swab.

If the body temperature has exceeded 38 degrees, it is recommended to take antipyretic drugs (Panadol, Nurofen and other analogues of Paracetamol and Ibuprofen).

When is dental care needed?

You can’t do without consultation or professional help from a dentist if:

there is increased swelling and pain in the gums;
The root molars have already shown themselves, but the “temporary” molars have not yet fallen out. They must be removed, otherwise the constants will grow crooked;
dairy ones have fallen out, but indigenous ones have not yet appeared. In such cases, they can erupt crookedly.

What to do if teeth grow crooked?

Make an appointment with an orthodontist and start treatment. Incorrect bite is corrected with plates, braces, trainers.

Can I get vaccinated when baby teeth are changing?

If the child has a temperature - it is impossible. If it does not affect your health and well-being in any way, you can.

To make sure that your child's teeth change is going well, we recommend that you have regular check-ups with a pediatric dentist.

And a permanent dentition is formed, which plays an important role in the development of the child.

In order for this period to pass smoothly and without complications, careful monitoring by the parents of the child's condition and compliance with hygiene standards is necessary.

The correct sequence of teething will affect the characteristics of the bite formation. Caring for oral health is an important investment in a child's future.

The child grows, and in the course of growing up, he experiences a period of teething twice. The first time around the age of four months to three years, a small child has milk teeth, which are temporary.

The change of milk teeth to permanent ones begins at about six years old, when the first incisors already begin to fall out in the child, giving way to new, permanent ones.

The age at which milk teeth begin to change in children depends on the individual state of the body.

In order for the dentition to be formed correctly and the teeth to erupt without problems, it is necessary to achieve a combination of several factors:

milk and permanent teeth must be properly formed;
the oral cavity and milk teeth need regular care, and if necessary, you need to seek help from a dentist. This will affect the overall health of the oral cavity and help to avoid a negative impact on the formation of a permanent dentition;
milk teeth should begin to fall out in time and not interfere with erupting new ones.

The rudiments of temporary teeth appear during the perinatal development of the child, so during pregnancy it is so important to eat foods rich in vitamins and minerals.

How strong the baby's teeth will be will be influenced by the mother's diet, genetics, and other factors - for example, complications that accompany pregnancy.

The first milk teeth in children begin to erupt, as a rule, in the period from four months of a child's life to a year.

In parallel with this process, and even earlier, almost from the birth of the baby, under the roots of the dairy, the rudiments of permanent teeth are already beginning to form.

Some parents believe that the condition of milk teeth will not affect the health of the dentition replacing them in any way, and they neglect the oral hygiene of the baby, and sometimes carelessly take care of milk teeth.

But in fact, everything is interconnected in the body, and often diseases of the temporary dentition then come around to the permanent one, because due to the proximity of the temporary and future permanent row to each other, the condition of milk teeth can greatly affect the health of new, only emerging teeth.

For example, when an infection enters the oral cavity, microbes through the gums and root canals can reach the rudiments of the future dentition and damage them.

In some cases, this even leads to adentia, as a result of which the health and integrity of the dentition is already disturbed at the formation stage. Caring for your child's teeth should start as early as possible.

How does the dentition change?

Renewal of the dentition, as mentioned earlier, begins at about the age of 6 years. During this period, the roots of the milk teeth dissolve, and the teeth are less firmly held in the jaw, loosen and gradually fall out naturally.

A new cutting tooth, as if along a beaten path, passes through the channel where the milk tooth grew, pushes it out and takes the vacant place.

The period of changing milk teeth to permanent ones is much less painful for the child than teething in infants.

In place of the fallen milk tooth, a small wound first appears - a bleeding hole, which usually heals quickly (literally within five to ten minutes) and does not cause discomfort to the child.

Sometimes children may not even notice a fallen tooth. During this period, the oral cavity requires special care so that bacteria do not get into the existing wound. It is better that by this time the child does not have plaque, stones or caries in the oral cavity.

Erupting, often the teeth change in children according to the same order in which milk teeth appeared before. The same principles work here.

New teeth appear in pairs, like milk teeth in due time - that is, paired teeth of the same name usually erupt at about the same time.

For example, lower front incisors or upper canines will grow at the same time. The lower pairs usually appear first (with the exception of the premolars).

During the change of the dentition, the milk teeth coexist with the permanent ones, so the health of the milk teeth greatly affects the new, just emerging dentition.

At first, the enamel of young permanent teeth will be soft and especially vulnerable to bacteria and any traumatic effects. The final maturation of the enamel may take from one and a half to two years.

The change of milk teeth in children corresponds to a certain schedule. But it should be borne in mind that all calculations show only average values.

Since all children are individual, some deviations from the schedule may normally be observed. Both the timing, at what age the teeth change, and the order of the change can change. Only significant differences can speak of pathological processes.

Do not forget about the influence of genetics - if the parents had teething features, then there is a high probability that they will also appear in the child.

In the period before updating the dentition, you can notice that the distance between the teeth increases in the baby. This is due to the fact that the children's jaw cannot fit a full row of teeth.

With age, the jaw increases, it has additional space necessary for the formation of a complete dentition.

When noticeable gaps appear, this indicates that the baby's jaw is growing and ready for change.

On this basis, it can be estimated that the eruption period will soon begin, and prepare for it in advance.

The central and lateral incisors, milk canines, the first pair of molars and premolars are subject to replacement.

Dental replacement schedule

The formed permanent dentition differs in structure from the temporary one. In the dentition in adults, there are normally from 28 to 32 teeth, while the milk dentition has only 20.

Another common misconception is that the first permanent teeth appear after the first pair of milk teeth fall out.

But in fact, the very first permanent teeth are the molars growing behind the second milk molars.

They begin to erupt usually as early as the fifth year of life or (on average) at about six or seven years of age, and cannot be replaced.

These molars do not replace milk ones, but immediately grow as permanent ones. That is, the "adult" dentition begins to form long before the first temporary teeth begin to fall out.

As mentioned earlier, there is an approximate timetable for the appearance of permanent teeth. The formation of the occlusion largely depends on the sequence in which they are cut, so the order in which they appear plays an important role.

After the appearance of the first molars, the central incisors appear to replace the fallen milk teeth at the age of six or seven years - first the lower ones, and then the upper ones.

After the central ones, the lateral incisors are usually cut through, and then the milk premolars are replaced by permanent molars.

The first to change are the premolars, which can also be called the “fourth teeth”. After them (or parallel to them) fangs are cut.

Then the "fifth teeth" begin to grow - the second premolars, replacing the second milk molars. And finally, at the age of about 11 years, the second molars appear in the child.

The jaw is fully formed when the third molars come out, they are also called “wisdom teeth”. The timing of their appearance is purely individual.

In some cases, they may never even erupt or appear completely. Usually third molars grow already in adults over the age of 20 years. But sometimes they make themselves felt at the age of 16, but not earlier.

In this case, different groups of teeth will erupt at different speeds. The second premolars grow the fastest - in six months they can grow by eight millimeters. The central incisor and canine can erupt almost as quickly.

On the basis of the described schedule, an approximate scheme for the change of milk teeth in a child can be drawn up.

The presented table demonstrates well how conditional all the terms of the formation of the dentition and the sequence in which the milk teeth change to permanent ones, therefore, it is impossible to accurately indicate the dates when the dentition will be formed.

The timing of the replacement of milk teeth (not including third molars) is usually seven to nine years. It is impossible to say for sure which milk teeth will appear first.

In caring for the health of their baby, parents should carefully monitor the process of updating the dentition, notice possible difficulties and help ensure that the replacement of milk teeth is successful, and young teeth are healthy and strong.
