# How many baby teeth should a baby have

In five-year-old children, after a two-three-year period of stability, a transitional process of formation of the dental system begins. New, larger teeth are cutting through, old ones to which the child has become used are loosened. The body is preparing to change the first infant teeth to adults. A bite begins to form. During this period, mothers need to be attentive to the state of the pediatric dental system, regularly show the baby to the dentist.

## By what age does the eruption of milk teeth end?

In young children, the teeth erupt individually. There are situations when the front incisors climb already in 4 months. In general, long-term observations show the pattern of filling the dentition in children.

To find out the number of teeth in the baby, you need to use the formula. We subtract from the age in months the number 4 and find out how many units can erupt in a child. For example, he is 10 months old. We consider according to the formula. 10 – 4 = 6. Thus, in 10 months, the crumbs are supposed to have 6 teeth. The table below shows the average time during which the first teeth erupt in children.

The table shows that the formation of the dentition is completed in 30 months. Thus, at the age of two and a half years, a healthy child has 20 teeth. A delay in the range of up to six months is considered normal. Moms do not have to worry yet. If the violation of the schedule exceeds 6 months, then you should visit the pediatric dentist.

## How many teeth should a baby have at 5 years old?

Five-year-olds have a whole milky row of 20 units. If by this time the composition is not completed, it is necessary to urgently show the child to the dentist. After 5 years, there is an active growth of the primordia of the permanent teeth and the replacement of milk teeth begins (for more details, in the article: when do baby’s teeth begin to fall out?). New teeth “push” the old ones from below, the roots dissolve. Baby teeth are loosened and ready to fall out (we recommend to read: when do children have milk teeth and how long should an adult have?).

In addition, at this age, behind the entire dentition in the place where there were unfilled areas, permanent chewing molars, the “sixes,” erupt. This process is painless and lasts up to 6 or 7 years. Some parents mistakenly consider them dairy and believe that they, too, will fall out. However, in humans, twelve units of the dentition are non-replaceable, that is, they immediately grow permanent. Thus, a five-year-old child may have from 20 to 24 teeth.

## When and how is the change of milk teeth to permanent?

Starting at the age of six, the milk series is replaced by a permanent one. Replacement occurs in the same sequence in which milk teeth erupted. This process stretches from 6-8 to 13 years, but the formation of the jaws does not end there. Following the loss of dairy cut:

• Not later than 14 years old – the second large molars ("sevens") (we recommend to read: the differences of milk teeth in children from the molars).
• From 15 years and older – the third molars, “eights” or “wisdom teeth” (for some people they appear before the age of 30 or do not erupt at all). The table shows the replacement periods for milk teeth.

## Parental actions after tooth loss

Before falling out, the baby tooth staggers, so its loss usually does not embarrass the child (more details in the article: a table with the terms of teething in children). Parents should be prepared for this moment and do the following when a fallout:

• a wound that was formed on the site of a lost tooth should be applied with a sterile swab to stop bleeding;
• do not feed the baby for 2 hours after falling out;
• for 2-3 days the child’s food should be warm and uniform in consistency, without solid particles;
• after each meal, rinse your mouth;
• the stopper from the coagulated blood that forms at the wound site cannot be removed, it will come out by itself;
• the hole should not be treated with antiseptics, especially hydrogen peroxide;
• child should be explained that you can not touch the wound with your fingers;
• If, after a fallout, the temperature has risen, you should immediately consult with your doctor.

## Care for baby and permanent teeth of a child

Parents should be very attentive to the state of the child’s mouth during the period when teeth fall out and are cut. In no case should not try to pull out a loose tooth. The dentist should be visited at least twice a year.

The rules for caring for a child’s oral cavity are:

• Periodically inspect the baby’s mouth. Any darkening of the teeth, swelling of the gums is a reason to visit a doctor.
• Carefully look at how the child eats. If the baby tries to have only one side of the mouth, then this should be alarming.
• Teaching a child to properly cleanse the oral cavity with a toothbrush and explain the necessity of this procedure. It is necessary to clean it twice a day – in the morning and in the evening. Buy baby "tasty" children’s toothpastes, change brushes every three months.
• After each meal, you need to rinse your mouth.
• Food should contain all the necessary vitamins and trace elements, and the amount of sugar should be controlled.

## Pathology of eruption and dental disease in children over 5 years old

With the growth and development of the jaw by the age of five, the child appears interdental spaces – tremes. This is a normal physiological process. They are needed for the proper placement of larger permanent teeth. Sometimes the cracks do not appear, or their size is insufficient. Then there is the risk that the dentition will be crooked. The lack of interdental spaces in a 6-year-old baby should worry his parents. The child must be shown to the doctor.

Children up to 4 years old sometimes beat a baby tooth while playing. In its place, a permanent grow not immediately. Long-term emptiness may adversely affect the adjacent units of the dentition. They may begin to move forward or sink. A timely appeal to the orthodontist will help solve this problem. In place of the lost item, the doctor will install a temporary replacement structure.

The doctor also controls the development of the jaws and the correctness of their joining. The bite is formed from 9-11 years of age. Parents usually do not notice anomalies. The early onset of bite correction is optimal at the age of 10 years. Orthodontic treatment at this time is the most painless, quick and effective.

As a rule, permanent units appear in children within the timeline described above (for more details see the article: When do children have molar teeth?). There are delays erupting. If the deviation from the norm is more than six months, then consultation of the dentist is necessary. The causes of significant violations can be the following:

• individual hereditary characteristics;
• weakened immunity;
• the presence of chronic diseases;
• calcium deficiency, vitamins and other elements.
