The appearance of the first tooth in a baby is an important event in the life of any parent. No less important is the change of the first children's teeth for permanent teeth, which is why parents have a question about how long their teeth grow in children. In this article we will expand this topic, find out how the first teeth grow , how many years should change to permanent. We will also answer the question at what age the teeth stop growing at all. Let's start with the appearance of the first tooth.
The first teeth of a child
The very first tooth in a baby grows around the age of six months. This is the incisor on the lower gum, and it is located in the center. But this is an average. This tooth can erupt in 3 months, and in a year, and in one and a half years. It happens that newly born babies already have one or a pair of teeth in their arsenal, but this happens quite rarely. The time of appearance of the first tooth depends on various factors, including the state of health and hereditary predisposition.
How old are milk teeth? A child’s tooth (both the first and all subsequent ones) can fully grow in a week or a few months.
It is worth remembering that the early appearance of the first teeth does not mean that the baby develops faster than his peers. You can not say that the child is underdeveloped if the teeth grow a little later. The terms of cutting are individual, like each individual baby. The baby’s health does not depend on how many teeth the child has in a certain period of time, of course, if the growth is not delayed very much. If by the age of 2 no teeth have appeared, this will be an occasion to visit a pediatrician and a pediatric dentist.
Signs of teething
Parents are wondering how long their teeth grow in children when they encounter problems at the first teething. Some children calmly endure this period of time, while others provide their mothers and fathers with sleepless nights and no less difficult days.
The first symptoms of tooth appearance are gum swelling and excessive salivation. At this moment, the child resembles a bulldog with drooling and trying to nibble everything that comes to hand.
Discomfort in the gums, pain (sometimes very severe) cause the child's vagaries. He can refuse food, not sleep at night, cry day and night. To alleviate the suffering of the baby, he needs to give a special teether toy, which consists of dense rubber. In addition to physical effects, you can also get specialized painkillers gels, which work like painkillers injections that put an adult to dental treatment. But these drugs are optional, you can quite survive without them, because our mothers and grandmothers somehow managed!
Symptoms of a cold, fever and diarrhea are not a sign of teething, but a consequence. During a difficult period for a child, he is more susceptible to diseases than at other times, because teething reduces immunity. You can’t attribute these symptoms to your teeth, you need to call a local pediatrician to prescribe treatment.
Deciduous teeth
Everyone knows how many teeth a person should have - 32. But do not think that by the age of five the child will already have a full arsenal. We will talk about how teeth grow in children and adults for how many years, and now we’ll deal with the issue of teething.
Even in the womb of a woman, her baby has the rudiments of milk teeth - on the 8-12th week of pregnancy. These rudiments are filled with mineral substances already in the second decade of the fetal development, so the expectant mother needs to take care of a rational and nutritious diet so that the mineral substances pass through her body to the child. The main essential substances are fluorine, calcium and phosphorus.
During pregnancy, the diet must include baked potatoes, dairy products, dried fruits, fish, as well as specially developed vitamin-mineral complexes for pregnant women. Only subject to the norm of minerals and vitamins, the baby’s teeth (both milk and permanent) will be strong, smooth, beautiful. Such teeth will not be afraid of caries, the baby will have healthy teeth.
In the period when the very first teeth begin to appear, the bookmark of permanent ones begins. Not only the baby's nutrition needs to be given attention, but also hygiene, because it is the basis of healthy teeth. You need to brush your teeth twice a day. Some parents believe that it is not necessary to treat caries on baby teeth and place fillings on them, because they will soon be replaced anyway. This is a delusion of many! As soon as the prerequisites for dental diseases appeared, they need to be eliminated, because caries will switch to a permanent tooth.
The growth of molar (chewing) teeth
How many years do children grow teeth? Complete eruption of the first incisors, canines and molars ends on average by one and a half years, sometimes later, at the age of two years.
The first masticatory usually begin to grow annually, and it is more painful than the growth of deciduous teeth. During this period, the kids begin to be very capricious during the day, do not sleep and cry at night.
At night, warm milk will help calm the baby. And in the afternoon he needs to be distracted by games, various activities, walks. It is very simple to do this, because the kids are endowed with the ability to quickly switch their attention. Also, the baby wants to gnaw everything, he does not need to refuse it. Just hide all the objects with which the child can choke, biting off part, on toys made of rubber and silicone.
How do children grow teeth: scheme
Each parent is interested in the order in which his child’s teeth should be cut. We suggest that you familiarize yourself with the list of how teeth grow in children, the scheme attached to the article will help to understand this clearly.
- The first two incisors of the lower gum in the center are on average from four months to a year, but most often in 6-7 months.
- Two incisors on the upper gum in the center - an average of 7 to 13 months.
- Then the incisors break through on the sides again on the upper gum - from 8 to 14 months.
- Incisors on the sides of the lower gum - 9-15 months.
- Anterior molars (chewing teeth) appear from above from about 13 to 19 months.
- Front molars (chewing) on ​​the lower gum - from 14 to 19 months.
- We expect fangs from above at the age of 16-22 months, from below - from 17 to 23 months.
- The second lower posterior chewing is erupted at 23-30 months.
- The second upper posterior chewing appears at 25-32 months.
We examined the order in which children grow teeth. Now we propose moving to the number of them up to six years.
The number of children's teeth
Having examined the previous section, you can understand how many teeth a child should have by two and a half years. Usually by the year he has already 8 teeth - 4 lower and 4 upper incisors. But sometimes this happens even later - to a year and a half, do not worry about this, because children develop individually.
By two years, the crumbs should have 16 teeth, and by three - 20. The child retains all these teeth for about seven years, after which there is a gradual replacement of dairy with permanent ones.
From the age of four, the child's jaws will begin to grow, and the facial bones will change, this is necessary in order to fit larger permanent teeth. During this period, chippings appear between the milk teeth, this is normal, they will not remain forever.
In rare cases, there is not enough space on the jaws for the location of all molars, and they begin to grow crooked. You can’t leave the situation to chance, you need to contact the orthodontist, he will advise you to wear dental plates or special trainers.
Change of first teeth to permanent
At the age of 5-7 years, baby teeth begin to stagger. This is due to the fact that the indigenous people destroy their root and push themselves out of the gums. The sequence of tooth loss is exactly the same as when teething.
It happens that the molar has already appeared on the surface, but milk still does not want to fall out. In this case, in order to avoid a crooked growth, you need to consult a dentist so that he removes the firmly stuck teeth.
The order of appearance of permanent teeth
- At the age of 6-8 years, the first root incisors in the center should appear.
- From 6 to 7 years old, lower anterior molars are replaced by primary lower front teeth. At the same age, the upper ones also change.
- From 7 to 8 years old, indigenous ones grow in place of the upper central milk incisors.
- In the interval from 7 to 8 years, the lower lateral milk incisors are replaced by radical ones.
- The upper radical incisors on the sides are 8–9 years old.
- From 9 to 11 years old - permanent fangs from below.
- By the age of 10–11 years, the first premolars from above grow between the masticatory teeth and fangs, and the lower ones, at 10–12 years.
- The second pair of premolars above and below appear in the interval from 10 to 12 years.
- At 11-12 years old, real fangs appear on the upper gum.
- From 11 to 13 years, the upper posterior posterior chewing teeth are changed by second molars. At the same age, there is a change in the lower ones.
- A third pair of molars above and below may appear at 15, and at 25, and at 50, and may not appear at all. These teeth are called wisdom teeth.
All dates indicated are approximate and may vary depending on the physiology, genetics and health of the child. It happens that the change of all teeth occurs up to 12 years, and sometimes it is delayed up to 15 years. Thus, it is easy to calculate how many teeth a child has under the age of 12 or 13 years. During this period, there should be 28 teeth, which are considered the main ones, because many third molars remove, because they interfere.
But what if the milk teeth fell out and the molars do not grow? We will talk about this in the next section.
Why do not permanent teeth grow for a long time?
To find out such a reason, you need to visit a specialist’s office. The dentist will examine the gums visually and, if necessary, schedule an x-ray.
The causes of pathology can be:
- physiological features of the child;
- genetic predisposition;
- lack of tooth germs.
Also, the reasons may be a lack of microelements, vitamins and minerals in the body, trauma to the jaw and premature removal of the first milk teeth.
Treatment
Most often, no treatment is required if it is a genetic predisposition. The molars will appear on their own, unnecessarily. In this case, the dentist can recommend enriching a child’s diet with foods rich in minerals and vitamins: vegetable oils, dried fruits, dairy products (especially cottage cheese), vitamins for children, fish and others.
If it is a trauma to the jaw, then radiography is needed. Based on these data, the doctor will recommend to wait until the problem is resolved on their own, in extreme cases, prosthetics may be required.
The most rare case is the absence of primordia. This pathology is most often formed in the womb, but it happens that the cause of this is transferred inflammatory diseases of the oral cavity.
How old are molars in humans?
The most recent teeth that appear in humans are wisdom teeth.
In ancient times, man had wide, powerful jaws, which allowed all teeth to appear outward, including the third pair of molars, or, in another way, wisdom teeth. Over time, the jaw began to decrease, it was affected by a change in nutrition - the thermally processed food did not require long chewing and strong loads, that is, it became softer.
Today, most adults already have wisdom teeth by the age of 25. But there are those who have third molars cut through at 30, 50, 40 years old. It happens that these teeth appear already in old age, and in some people they do not grow at all.
