The appearance of the baby's first tooth is an important event in the life of any parent. Equally important is the change of the first children's teeth to permanent ones, which is why parents have a question about how old children's teeth grow. In this article, we will expand on this topic, find out how the first teeth grow, at what age the change to permanent teeth should occur. We will also answer the question at what age teeth stop growing completely. Let's start with the appearance of the first tooth.

Baby's first teeth

The very first tooth in a baby grows at about the age of six months. This is an incisor on the lower gum, and it is located in the center. But this is an average. This tooth can erupt at 3 months, and a year, and a year and a half. It happens that newly born babies already have one or a pair of teeth in their arsenal, but this happens quite rarely. The timing of the appearance of the first tooth depends on various factors, including the conditionhe alth and hereditary predisposition.

How old do milk teeth grow? A child's tooth (both the first and all subsequent ones) can fully grow both in a week and in several months.

It is worth remembering that the early appearance of the first teeth does not mean that the baby is developing faster than his peers. It cannot be said that the child is underdeveloped if the teeth grow a little later. The timing of cutting is individual, like each individual baby. The he alth of the baby does not depend on how many teeth the child has in a certain period of time, of course, if growth is not delayed much. If not a single tooth has appeared by the age of 2, this will be an occasion to visit a pediatrician and a pediatric dentist.

Signs of teething

Parents wonder how old children's teeth are when they encounter problems with their first teething. Some children calmly endure this period of time, while others provide their moms and dads with sleepless nights and no less difficult days.

The first symptoms of teething are swollen gums and excessive salivation. At this moment, the child resembles a bulldog, who is drooling and trying to gnaw everything that comes to hand.

Discomfort in the gums, pain (sometimes very strong) cause the child's whims. He can refuse food, stay awake at night, cry all day long. To alleviate the suffering of the baby, he needs to be given a special teether toy, which consists of a denserubber. In addition to the physical impact, you can also purchase specialized anesthetic gels that work like anesthetic injections that are given to an adult before dental treatment. But these drugs are optional, you can completely survive without them, because our mothers and grandmothers somehow coped!

Cold symptoms, 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 write off these symptoms on the teeth, you need to call the local pediatrician to prescribe treatment.

Growth of baby teeth

Everyone knows how many teeth a person should have - 32. But do not think that by the age of five a child will already have a full arsenal. We will talk about how old teeth grow in children and adults in the future content, and now we will deal with the issue of teething milk teeth.

Even in the womb of a woman, her baby has the rudiments of milk teeth - at the 8-12th week of pregnancy. These rudiments are filled with minerals already in the second decade of fetal development, so the expectant mother needs to take care of rational and nutritious nutrition so that minerals enter through her body to the child. The main essential substances are fluorine, calcium and phosphorus.

When pregnant, include baked potatoes, dairy products, dried fruits, fish, and specially formulatedvitamin and mineral complexes for pregnant women. Only if the standard of intake of minerals and vitamins is observed, the baby's teeth (both dairy and permanent) will be strong, even, beautiful. Such teeth will not be afraid of caries, the baby will have he althy teeth.

In the period when the very first teeth begin to appear, the laying of permanent teeth begins. Not only the nutrition of the baby needs to be paid attention, but also hygiene, because it is the basis of he althy teeth. You need to brush your teeth twice a day. Some parents believe that it is not necessary to treat caries on milk teeth and put fillings on them, because they will change soon anyway. This is a delusion of many! As soon as the prerequisites for dental diseases appear, they need to be eliminated, because caries will pass to a permanent tooth.

Growth of molars (chewing) teeth

Until what age do children's teeth grow? Full 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 chewing gums usually start to grow in a year, and this is more painful than the growth of milk teeth. During this period, babies begin to be very capricious during the day, not sleep and cry at night.

Warm milk will help soothe your baby at night. And during the day he needs to be distracted by games, various activities, walks. To do this is very simple, because the kids are endowed with the ability to quickly switch their attention. Also, the baby will want to gnaw everything, you don’t need to refuse him this. Just hide all the things that the child can choke on after biting off the part, on toys made of rubber andsilicone.

How children's teeth grow: diagram

Every parent wonders in what order his child's teeth should erupt. We suggest that you familiarize yourself with the list of how teeth grow in children, the diagram attached to the article will help you understand this clearly.

1. The first two incisors of the lower gum in the center - on average from four months to a year, but most often at 6-7 months.
2. Two incisors on the upper gum in the center - an average of 7 to 13 months.
3. Next, the incisors break through on the sides again on the upper gum - from 8 to 14 months.
4. Incisors on the sides on the lower gum - 9-15 months.
5. The front molars (chewing teeth) appear from the top around 13 to 19 months.
6. Anterior (chewing) molars on the lower gum - from 14 to 19 months.
7. Fangs from above are expected at the age of 16-22 months, from below - from 17 to 23 months.
8. The second lower posterior chewing teeth erupt at 23-30 months.
9. Second upper posterior chewing teeth appear at 25-32 months.

We looked at the order in which children's teeth grow. Now we propose to move to the number of them up to six years.

Number of baby teeth

After reviewing the previous section, you can understand how many teeth a child should have by two and a half years. Usually by the year he already has 8 teeth - 4 lower and 4 upper incisors. But sometimes this happens even later - by the age of one and a half, you should not worry about this, because children developindividually.

By two years old, a baby should have 16 teeth, and by three - 20. A child retains all these teeth until about seven years old, after which there is a gradual replacement of dairy teeth with permanent ones.

From the age of four, a child's jaws will begin to grow and facial bones will change to accommodate larger permanent teeth. During this period, gaps appear between the milk teeth, this is normal, they will not remain forever.

In rare cases, there is not enough space on the jaws to accommodate all the molars, and they begin to grow crooked. You can’t leave the situation to chance, you need to contact an orthodontist, he will advise you to wear dental plates or special trainers.

Change the first teeth to permanent

At the age of 5-7 years, a child's baby teeth begin to loosen. This is due to the fact that the indigenous destroy their root and push it out of the gums. The sequence of teeth falling out is exactly the same as when teething.

It happens that the molar has already appeared on the surface, but the milk tooth still does not want to fall out. In this case, in order to avoid crooked growth, you need to consult a dentist so that he removes firmly planted teeth.

The sequence of appearance of permanent teeth

1. At the age of 6-8 years, the first molars in the center should appear.
2. From 6 to 7 years old, the lower front molars are replaced by the molars of the lower front teeth. At the same age, the upper ones also change.
3. From 7 to 8 years in place of the upper central dairyincisors grow molars.
4. In the interval from 7 to 8 years, the lower lateral milk incisors are replaced by molars.
5. Upper molars on the sides - at 8-9 years old.
6. From 9 to 11 years - permanent fangs from below.
7. By the age of 10-11, the first premolars grow from above, the lower ones - at 10-12 years old between the milk chewing teeth and canines.
8. The second pair of upper and lower premolars appear between 10 and 12 years of age.
9. At 11-12 years old, real fangs appear on the upper gum.
10. From 11 to 13 years old, the upper posterior milk chewing teeth are replaced by second molars. At the same age, the lower ones also change.
11. The third pair of molars from above and below may appear at 15, and at 25, and at 50, or may not appear at all. These teeth are called wisdom teeth.

All times shown are approximate and may vary depending on the physiology, genetics and he alth 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 under the age of 12 or 13 years has. During this period, there should be 28 teeth, which are considered the main ones, because many third molars are removed, as they interfere.

And what if the milk teeth fell out, but the molars do not grow? We'll cover that in the next section.

Why do permanent teeth take so long to grow?

To find out such a reason, you need to visit a specialist's office. The dentist will examine the gums visually and, if necessary, prescribe an x-ray.

The causes of pathology can be:

• features of the physiology of the child;
• genetic predisposition;
• lack of tooth germs.

Also, the reasons may be a lack of trace elements, vitamins and minerals in the body, injury to the jaws and premature removal of the first milk teeth.

Treatment

Most of the time, no treatment is needed if it's a genetic predisposition. The molars will appear on their own, unnecessarily. In this case, the dentist may recommend enriching the 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's a jaw injury, then an X-ray is needed. Based on these data, the doctor will recommend waiting until the problem is solved on its own, in extreme measures, prosthetics may be required.

The rarest case is the absence of germs. This pathology is formed most often in the womb, but it happens that the transferred inflammatory diseases of the oral cavity become the cause of this.

Until what age do molars grow in humans?

The most recent teeth that a person has are wisdom teeth.

In ancient times, a person had wide, powerful jaws that allowed all teeth to appear at once, including the third pair of molars, or in other words, wisdom teeth. Over time, the jaw began to decrease, this was influenced by a change in nutrition - thermally processed food does notrequired a long chewing and heavy loads, that is, it became softer.

Today, most adults already have wisdom teeth by the age of 25. But there are those whose third molars erupt at 30, 50, 40 years. It happens that these teeth appear already in old age, and in some people they do not grow at all.
