Changing children's baby teeth to permanent ones is always an exciting time for parents. This process is quite lengthy and often painful for the child, because it can be accompanied by various inflammations and discomfort. To help parents, for a better understanding of the physiological processes associated with the formation of teeth, dentists offer to look at the pattern of loss of baby teeth in children.
Bookmarking teeth
The formation of baby teeth occurs at approximately 4-6 weeks of fetal development. At the same time, the formation of the fundamental elements occurs much later - during the first months of the child’s life. For this reason, new mothers who are bottle-feeding are strongly recommended to supplement their baby’s diet with calcium. This substance promotes the proper formation of tooth enamel.
At an early age, unprotected baby teeth are extremely susceptible to carious lesions. Parents should monitor this closely, as infection can subsequently cause destruction of permanent teeth. The fact is that the rudiments of permanent teeth are in close proximity to the roots of milk teeth, so as soon as you discover dark spots on your child’s enamel, immediately go to pediatric dentistry.
What causes baby teeth to fall out?
Before permanent teeth appear, interesting physiological changes occur, such as the spontaneous resorption of the roots of baby teeth. This is why they begin to wobble and fall out. The germs of permanent teeth are located between the roots of milk teeth, because of this, resorption begins from the place where the root adheres to the germ of a permanent tooth. Resorption starts from the apex of the root and gradually moves towards its base. As soon as this process approaches the neck, the tooth falls out.
Children erupt 20 baby teeth. In the oral cavity, adults have from 28 to 32 teeth. Typically, all baby teeth fall out. In a child by the age of 14, they should be completely replaced by permanent ones.
Baby teeth in children: loss pattern
Many mothers are concerned about the question of when their children’s baby teeth begin to fall out. As a rule, this process starts immediately before primary school, that is, at the age of 6-7 years. In this case, the pattern of loss of baby teeth in children is similar to the sequence of their eruption. Only the fangs differ, which are replaced later, by the age of 13.
The order in which baby teeth fall out is the same for almost all children. First, molars grow - molars, which were absent in the “milk” set. As soon as there is enough space in the child’s jaw, “sixes” begin to appear. Only after this comes the time to change temporary teeth.
First, the lower incisors fall out, and then the upper ones. After this, the premolars appear at about 9-11 years of age. The last in line are the fangs, which usually fall out by the age of 10-12 years. At the same time, there should already be molars in the child’s mouth. After 18 years, third molars or, as we used to call them, wisdom teeth begin to emerge. However, they do not appear in everyone, which, by the way, does not indicate the presence of any pathologies.
Main deviations when changing teeth.
- “Shark mouth” - when the milk teeth have not yet fallen out, but the molars have already grown in the second row.
You need to go to the dentist and have temporary teeth removed, otherwise your bite will suffer.
- Untimely change of teeth - when baby teeth begin to fall out before 5 years of age or after 8 years of age.
The reasons for this deviation may be trauma, caries, nutrition, heredity, infectious diseases, hormonal problems, as well as various diseases (diabetes, leukemia, immunodeficiency, etc.).
- The baby tooth has fallen out, but the molar tooth is not growing.
An x-ray will help identify the cause. For example, if there is no tooth germ in the picture, this is edentulous (the tooth simply has nothing to grow from). Here you will need the help of a prosthetist.
These problems occur in approximately every tenth child. Fortunately, qualified dentists know what to do in this or that case!
What should parents do?
The process of changing teeth in children worries parents, but this is quite natural, and most children do not experience significant pain. However, this does not relieve parents of the need to constantly monitor the condition of their child’s oral cavity. There is no need to remove baby teeth yourself. When the time comes to say goodbye to a tooth, a certain mechanism is activated in the child’s body that dissolves the milk tooth roots. You should seek help from a specialist only if the baby tooth does not want to fall out, but the permanent one is already beginning to appear.
After a tooth falls out, you may experience some bleeding. If desired, have your child rinse his mouth with a solution of soda with a drop of iodine as a preventative measure.

Features of replacing baby teeth with permanent ones
Often, during the process of replacing teeth, certain features and unusual situations are observed that become a cause for concern for parents.
Let’s briefly look at the most common parental questions: 1. What reactions can a child’s body have when baby teeth fall out and during the period of growth of permanent teeth?
Answer: The process of replacing teeth is virtually painless. Baby teeth fall out on their own after complete resorption of the root or are removed at home, or better yet, by a pediatric dentist, when the permanent tooth is already growing and the baby tooth has not yet fallen out. The eruption of permanent teeth is not accompanied by pain. In very rare cases, there may be a slight increase in temperature, abdominal pain, and itching of the gums. No treatment is required, but consultation with a dentist is recommended.
2. Why do paired teeth not fall out at the same time, but sometimes with a long period of time?
Answer: Firstly, this is what nature intended, and for each child individually. Secondly, it all depends on the time period of resorption of the root of a baby tooth. If baby teeth have been treated or filled, then the root resolves much more slowly, sometimes it does not resolve at all. Filled roots of baby teeth often have to be removed by a dentist because they may not fall out on their own.
3. Why does a lot of time often pass between the loss of a baby tooth and the appearance of a permanent one?
Answer: As a rule, the front teeth grow quickly. But premolars ( baby molars ) and canines are often delayed. After a temporary tooth falls out, it may even take 4-6 months until a permanent tooth erupts in that place. Therefore, you just have to wait and get quality care. But if the period exceeds six months, and you are very worried, come to the appointment. After the examination, the doctor will decide whether it is necessary to stimulate the growth of a permanent tooth.
4. Which teeth should 8-year-old children change?
Answer: By the age of eight, a child should normally have the following permanent teeth - 6th molars, 4 upper incisors and 4 lower incisors. Plus/minus six months is the norm.
5. Why is it necessary to treat caries in children if you then have to pull out the filled roots of baby teeth?
Answer: We have already written (“What is the danger of premature removal of baby teeth”) that an empty space in the dentition contributes to the shifting of existing baby teeth, which means that the rudiments of permanent teeth underneath them shift and they grow incorrectly - in one place they overlap each other each other, and in the other, cracks form. A treated, filled baby tooth preserves space for a permanent tooth. An untreated tooth infects the germ of the permanent tooth with caries, which can lead to deformation or even the absence of the latter.
6. Why does a child aged 7-14 years sometimes experience toothache , but the teeth are all intact?
Answer: Yes, this phenomenon occurs, but it is not the tooth itself that hurts, but the jaw, which is rapidly growing at this age. Permanent teeth are almost twice the size of baby teeth, which means they need much more space. If the new teeth are large, then they can even overlap each other, get out of the dentition, or grow at an angle to each other. As the jaw grows, they settle into place and align. But only a qualified specialist can correctly assess such a situation and the danger of developing defects and anomalies, so consult an orthodontist at the Utkinzub clinic.
7. At what age should a bite be corrected?
Answer: The best option is before the change of baby teeth, from 4-5 years. In this case, permanent teeth will grow, as a rule, evenly, in the place intended by nature. There will be no need for subsequent long-term bite correction. In any case, if there is a malocclusion, the sooner you contact a qualified orthodontist, the faster and better the problem will be eliminated. Read more in the article “Treatment of malocclusions.”

How many baby teeth do children lose?
The very first teeth appear between the ages of six months and one year. First, the incisors appear, located below and in the center, then the upper ones, and only then the lower lateral and upper lateral ones. This is followed by the first molars, canines and second molars. In pediatric practice, such a concept as a dental formula is used, that is, a standard dental set for children: 2 incisors, 2 molars and a canine. Multiplying the data obtained by four, we get 20 – the number of baby teeth is normal. Accordingly, the same number of baby teeth fall out.

In what order do teeth change?
As soon as baby teeth fall out, permanent teeth erupt at the same time. There is a close relationship between these two processes. They appear in the same order as they fall out: first, the incisors change, then the first and second premolars, and then the turn comes to the canines.
- The eruption of the first molars (sixth teeth) occurs long before the process of changing teeth; they are immediately permanent.
- Second molars begin to grow in the spaces created by jaw growth.
- In many people, “wisdom teeth” or third molars may not grow at all, or their eruption is very problematic.
Anatomy of molars
There are three parts to a molar: The crown is the protruding part of the tooth. The root is that part of the tooth that is located under the gum and is held in the jaw bone with the help of connecting bundles. There can be several or one root in a tooth, it all depends on the specific tooth. The neck is the narrowest part of the tooth, located between its root and crown. The top of the tooth is covered by enamel - the hardest and most durable part of the tooth. After the baby’s tooth has erupted, it is covered with cuticle on top of the enamel - a thin transparent layer, which after some time is replaced by a film called pellicle. At the base of the tooth is dentin, which is covered with cement in the root area. Inside the tooth there are root canals and pulp, which is loose tissue filled with blood vessels and nerve endings.
Why can a lot of time pass between the loss of baby teeth and the eruption of permanent teeth?
Most often, the front teeth grow quickly. And canines and baby molars (premolars) can be delayed. After a temporary tooth falls out, it may even take 4-6 months until a permanent tooth erupts in that place. Just expect it and take good oral care. But if this period begins to exceed six months, so as not to worry, it is better to visit a doctor. After examining the child, he will be able to decide whether the permanent tooth needs to be stimulated to grow.
When baby teeth erupt
The timing of the appearance of baby teeth depends on the hereditary factor and the baby’s nutrition. On average they look like this:
- the first lower incisors appear at 6-9 months, and the first upper ones at 7-10;
- second upper and lower - at approximately 9-12 months;
- first upper “root” (chewing) – 12-18 months;
- first lower chewing – 13-19 months;
- second lower “root” – 20-23 months;
- second upper chewing – 24-26 months;
- fangs erupt between 16-17 and 20-22 months.
Orthodontic treatment – caring for the future
Some parents do not attach importance to the fact that the baby tooth has not yet fallen out, but the permanent one is already emerging. Or, on the contrary, the temporary one is lost early, and the tooth that replaces it does not grow. If you notice deviations, we recommend that you contact an orthodontist as soon as possible, who will provide effective treatment.
For example, with the premature loss of a baby tooth, the free space is very quickly taken up by neighboring teeth. There is not enough space for a permanent one. Therefore, it is very important when forming a temporary occlusion to fill such gaps, preventing the occurrence of an occlusion anomaly. To hold space for a permanent tooth, orthodontics uses a plate with artificial teeth. For single defects, a non-removable “ring-loop” design is most often used. The device does not cause discomfort, and the child wears it until the permanent tooth erupts.
The product manufacturing process is standard: impressions are taken, models are made, and the design is created in the laboratory within two weeks. Its fixation takes 15-20 minutes. After installing the device, you do not need to drink or eat for 2 hours. It is better to limit the consumption of “pulling” foods - toffees, chewing gum, etc.
