How old do baby teeth change

The period when the milk teeth change and a permanent dentition is formed plays an important role in the development of the child.

In order for this period to go smoothly and without complications, careful control by the parents of the child’s condition and his compliance with hygiene standards is necessary.

Proper teething sequence will affect the characteristics of the formation of bite. Caring for the health of the oral cavity is an important contribution to the future of the child.

What affects the formation of canines, incisors and molars?

The child grows, and in the course of growing up, he twice goes through a period of teething. For the first time around the age of four months of life up 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 of the child begin to fall out, giving way to new, permanent ones.

The individual condition of the body affects how many years baby teeth begin to change.

In order for the dentition to be formed correctly and the teeth erupt without problems, a combination of several factors must be achieved:

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

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

The strength of the baby’s teeth will be influenced by the mother’s diet, genetics, and other factors, such as complications that accompany a pregnancy.

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

Parallel to this process and even earlier, practically from the birth of a baby, the rudiments of permanent teeth begin to form under the roots of dairy ones.

Some parents believe that the state of the milk teeth does not affect the health of the dentition that replaces them, and they neglect the oral hygiene of the baby, and sometimes carelessly take care of the milk teeth.

But in fact, everything is interconnected in the body, and often the diseases of a temporary dentition are then shaken to a permanent one, because due to the proximity of the temporary and future permanent row to each other, the condition of milk teeth can have a strong effect on the health of new, only forming teeth.

For example, if an infection gets into the oral cavity, microbes through the gums and root canals can reach the germs 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 disturbed at the stage of formation. Caring for the baby’s teeth should start as early as possible.

How is the dentition?

Renovation 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, loosened and gradually fall out naturally.

A new cutting tooth, as if on a beaten track, passes through a canal where a milk tooth has grown, pushes it out and takes up the vacated space.

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

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

Sometimes children may not even notice a dropped out 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 mouth.

When cutting through, the teeth often change in children according to the same order in which milk ones appeared before. About the same principles work here.

New teeth appear in pairs, like milk teeth in their time, that is, similarly named twin teeth usually erupt approximately simultaneously.

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

During the change of the dentition, dairy coexist with permanent ones, therefore the health of milk teeth strongly influences the new, only forming dentition.

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

Changing baby teeth in children corresponds to a certain schedule. But it should be borne in mind that all calculations show only averaged values.

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

Do not forget about the influence of genetics – if the parents were observed features of eruption, then there is a high probability that they will appear in the child.

In the period before the renovation of the dentition, it can be noted that the distance between the teeth increases with the baby. This is due to the fact that the children’s jaw can not fit a full range of teeth.

With age, the jaw increases, additional space appears on it, which is necessary for the formation of a complete dentition.

When noticeable shcherbinki appear, it indicates that the baby’s jaw is growing and ready to change.

On this basis, it is possible to estimate that the period of eruption will soon begin, and to prepare for it in advance.

The central and lateral incisors, milk teeth, the first pair of molars and premolars are to be replaced.

Dental row change schedule

Formed permanent dentition differs in structure from the temporary. In the dentition, adults normally range from 28 to 32 teeth, while the milky dentition has only 20.

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

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

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

These molars do not replace dairy, and immediately grow as permanent. That is, an “adult” tooth row begins to form long before the first temporary teeth begin to fall out.

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

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

After the central ones, the lateral incisors are usually cut, and then the dairy premolars are replaced by the root constants.

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

How old do baby teeth change

Then the “fifth teeth” begin to grow – the second premolars, which replace the second milk molars. And finally, at the age of about 11 years, the second molars appear in the child.

The jaw is completely formed when 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 cut through or appear completely. Usually, third molars grow in adults over the age of 20 years. But sometimes they make themselves known and in 16 years, but not before.

At the same time, different groups of teeth will erupt at different speeds. The second premolars grow the fastest – in six months they can grow by eight millimeters. Almost as quickly, the central incisor and canine can be cut.

On the basis of the described schedule, an approximate scheme for changing baby teeth in a child can be made.
