When the drop milk and permanent teeth grow?


How is the replacement of milk teeth by permanent teeth? What affects the loss and eruption of the teeth? What should parents do when their baby's teeth fall out? Than to help the child

In humans, the first set of teeth is temporaryAnd called dairy. The lifetime of this set, when it is fully formed, is relatively small. Temporal units erupt in infancy.

Change Dairy Teeth in detectiveTh On permanent starts at about 5 years, and ends at 15 years.

Substitution physiology

When the drop milk and permanent teeth grow?By the age of 5, the interdental space becomes wider. This is how the jaw is prepared for the process of change.

If the distance between the teeth does not increase, thenIt is necessary to show the child to the doctor, because, due to lack of space, they can (and will) grow through the side of the gums (horizontally) or, conversely, into the oral cavity.

Between the roots of dairy are the rudimentsConstant, so the process of shifting begins with the resorption of the root of the milk tooth from the side adjacent to the rudiment. The process develops from the apex of the root and gradually reaches the base. At this time, the dairy begins to stagger, and when the cervix is ​​hit, it falls out.

All people always grow 20 milk teeth, and they drop out absolutely everything. Maximum of 15 years, they must be replaced by permanent units.

The order of changing dairy teeth in children

The process takes place in two directions at the same time: the milk falls out, the permanent ones erupt. An important factor in this period is also what will be the first to fall out.

Drop dairy will be in the same order in which they grew up. The scheme is always the same: at first the incisors change, followed by premolars, and lastly - fangs.

It should be noted that the first molars grow at onceConstant and this occurs even before the shift process begins. The second molars arise on empty places, which were formed during the growth of the jaw. A third of the molars, or wisdom teeth, some people do not grow at all, because they are no longer necessary.

The following factors influence the change:

  • Duration of breastfeeding;
  • The genotype of the baby;
  • Infections suffered by a child;
  • The presence of toxicosis in a woman during pregnancy.

Table of milk teeth changes in children:

  • 6-7 years - the first molars;
  • 6-8 - central, and after them and lateral incisors;
  • 10-12 - premolars;
  • 9-12 - fangs;
  • 11-13 - second molars;
  • 17-25 - third molars.

When will dairy begin to fall out?

By the age of 5 they begin to loosen up. It is worth noting that the deviation from the deadline is a violation. For example, early eruption most often indicates endocrine disorders, and a delay in growth - about metabolic disorders, rickets, chronic infections, etc.

Diagram of milk teeth change in children:

  • 6-7 years - lower, and then upper central incisors;
  • 7-8 - lateral incisors;
  • 8-10 - the first molars;
  • 9-11 - fangs;
  • 11-13 are the second molars.

However, the timing may vary greatly. In some children, they begin to fall earlier, others - later. This process depends on many factors and the permissible fluctuations range from 4 to 8 years.

In addition, the order of deposition is also important. Among dentists there is the term "spatial balance", by which is meant that the milk units are responsible for the location of the radicals, as well as for their location in the oral cavity.

Temporary retains the spatial balance until it falls. Early or late fallout can lead to eruption disorders.

Causes of early loss may include forced tooth extraction, trauma, a growing tumor, severe pressure from neighboring teeth, or an abnormally deep bite.

As a result, spatialBalance, that is, the change to permanent teeth is hampered by displaced units that have occupied free space. As a result - curvature, which can distort facial features, natural facial expressions and cause speech defects. To avoid this, the orthodontist installs a special retention plate.

But the causes of late fall is rickets, a transmitted infection, chronic dyspepsia, hereditary predisposition or phenylketonuria.

When the drop milk and permanent teeth grow?Often, the physiological delay of prolapse makes permanent units more resistant to tooth decay, but if this process did not begin by the age of 8, then there may be no rudiments.

There are cases when dairy wander, but notDrop out. At the same time, there are already standing next to them, and since they do not have enough space, they grow up in the wrong position, speaking out of the dentition. In this situation, you need to contact a specialist for immediate correction.

The timing of the change of infant teeth in children

In total, the replacement process takes 5 to 8 years. It is necessary to count from the loss of the first unit and to the loss of the last one. Violation of these terms can be caused by the genetic factor, the quality of drinking water and diet. The loss of the last temporary tooth is considered to be the norm by the age of 14 years.

Emerging problems

Although the process of change is physiological, many parents face a number of problems

"Shark Jaw". Normally, the roots first dissolve, then the teethDrop out (milk), pushed by the constant. But sometimes this process fails and then the permanent one has time to grow earlier than the dairy one will drop out. It happens that the child is present at once two rows, that is, both dairy and permanent.

Dentists confirm that such a violation is notCauses problems in the future, after all, after the dairy, a permanent unit still takes its place. However, parents should reduce the baby to a consultation with the doctor if the milk tooth does not fall within 3 months.

Severe discomfort and pain - commonPhenomenon. It is also possible to raise the temperature to 38 degrees. In rare cases, a reddish or bluish color is formed on the edges of the gum. If it is pierced, a bloody liquid appears.

A few weeks later, in her place,To appear a tooth. Inflamed gums are lubricated with special pastes and gels. However, with pronounced phenomena, you need to visit a doctor. In particular, it is difficult to change the molar teeth in children.

Milk fell, but the constant does not grow. This situation can arise for two reasons. Firstly, due to retention, the eruption delays. Partial retention - part of the crown was cut, and the other remained under the gum. When the tooth is formed, visible in the jaw, but does not appear - this is a complete retention.

Violation can be caused by prematureThe removal of the milk tooth, the delay of its loss, the wrong and too deep location of the rudiment. Secondly, the anomaly arises because of adentia - the absence of a tooth.

A partial adentia is a phenomenon when inThere is no one or more units. The cause of the violation is the death of the rudiment. This is due to the pathology of intrauterine development of the fetus, but this condition is very rare.

What should parents do?

Even after reaching three years of the baby can be accustomed toTo daily oral hygiene, that is, to brushing your teeth. Brushes for cleaning are recommended to choose soft, with rounded tips of bristles. The paste is used only for children, since it does not cause allergies and is safe if swallowed.

After each meal, rinse your mouth with water. Such a simple measure will help protect against caries.

When the drop milk and permanent teeth grow?The child should have a full-fledged diet. In particular, it is important to consume foods with a high calcium content, since the enamel of the incised molars is initially not sufficiently mineralized.

After falling out, a bleeding wound may occur. It is necessary to make a tampon of sterile cotton wool and let the baby bite it.

If the oral cavity has an inflammatory process, or the baby feels discomfort from a loose tooth, then you must visit a dentist.

The process of forming the jaw can affectMany factors, so that even the shift table is not always effective and you need to approach this question individually in each case. Healthy teeth for your kids!
