What are the terms of dentition?

With what impatience we wait, when the first tooth will cut through our baby! The timing of teething is not only due to heredity. Important factors are climate, food quality, temperature. For example, the hotter the climate, the earlier the timing of teething in the child comes .

In a person during his entire life, twenty teeth change (they are called dairy) and eight (or twelve) are cut and remain for life without changing (radical). The timing of eruption of permanent teeth (molars) varies greatly. They begin to erupt usually at the sixth year of life, and they can even finish cutting off even in forty years. Approximately from six till fifteen years at the person a bite replaceable (presence simultaneously both milk or dairy, and a constant teeth). This period usually lasts until thirteen years. Then a permanent bite (28-32 teeth) is formed, on each side from 14 to 16 teeth. Permanent teeth are cut in this order: molars first, incisors central, incisors lateral, premolars first, canines, premolars second, second molars and wisdom teeth. Teeth erupt first on the lower jaw, and then on the upper jaw. The first premolars are an exception.

Specify the exact timing of eruption of milk teeth is impossible, because for each child they are individual. And they can vary considerably. But still the general scheme, tentative, exists.

The newborn has no teeth at all. Although there are rare cases when the teeth grow during intrauterine development, but this is a deviation from the norm.

The first to appear on the mandible are the central incisors, and soon on the upper. This happens when the child is about six months old. By eight months, lateral incisors appear (first on the lower jaw, and then on the upper jaw). By the sixteenth month, the first molars erupt, followed by the fangs. Approximately to the twentieth month of life, the second molars appear. On them, and ends the formation of a bite.

Earlier terms of teething were explained by rickets. Just like the asymmetric arrangement. However, in reality this is not an indicator of a violation in the development of your child. Long observations have shown that such "violations" are peculiar to some children developing in the rest is absolutely normal. However, parents have the right to be alert when:

• The timing of teething is prolonged for more than two months (according to the norm);
• Teeth erupt more than two months before the norm;
• Missing one of the teeth;
• Incorrectly formed the tooth itself;
• The tooth grows before birth.

The delay in teething in dentists is called retention. Usually this happens with canines, sometimes touches molars and incisors. If the delay comes with a deviation of a month or two, then you should not worry. A longer delay may indicate some kind of pathology. Usually this is the result of diseases that the mother suffered during pregnancy, or the diseases of the child itself. However, timely eruption can be prevented by extra supercomplete teeth (this also occurs, although very rarely). Earlier eruptions testify to abnormalities in the endocrine system. When the timing of teething significantly deviated from the norm, be sure to seek advice from a dentist and pediatrician.

In conclusion, a few words about how to alleviate the discomfort experienced by a child at a time when his teeth are chapped. At this time, the baby does not just cry, he can scream very loudly, he can get a fever and stay for more than a day. Give the child something to eat. This will help ease the pressure and partially relieve the pain. You can use a special dental gel for toddlers (it is sold in pharmacies without a prescription). A teetotaler (a rubber toy with water inside), which is cooled and given to the child for relief of condition (the cold well removes painful sensations) very well helps. If the baby has fever, consult a pediatrician who will tell you the appropriate antipyretic agent, according to your child's age.
