Root or dairy: the child's teeth are cut
The laying of teeth and the formation of their primordiabegins in the child at the 7-8th week of embryonic development, and hard tissues of teeth are formed at the end of 16-17 weeks. Therefore, all children are born with formed teeth that are waiting for their development to appear from the gums.
Usually this happens when the toddler turnshalf a year, but there are cases of both earlier and later teething. When a child's teeth are cut, this causes a lot of inconvenience not only to himself, but also to his parents - because the baby's state of health worsens, he becomes restless, capricious, worse eating, worse sleeping and constantly asking for pens. But these are temporary signs that eventually pass.
Normally, the child's teeth are always cut in pairs, inspecific sequence. This helps to form a proper bite. Milk teeth in full set appears in the baby to two and a half years. After this, there comes a period of "dental calm".
Constant teeth in children begin to appear in theaged 6-7.5 years: baby teeth begin to fall out, and in their place appear indigenous. Most often this process begins with the lower incisors. Do not worry if your baby's teeth have fallen out, and the permanent ones do not appear for a few months after that. Go to the reception to the dentist to see how the rudiments of the molars are located, how they are formed and when they are ready to erupt.
First, the nature of the replacement of incisors: upper and lower. It is not accidental that a child's teeth are cut in such a clear sequence. The incisors are most worn out in the process of biting and chewing, and therefore they change to permanent ones first. Then the same order in which the baby's teeth appeared appeared.
When a child's molar teeth are cut, he experiences this much more quietly than the process of appearance of the first dairy. Temperature and pain are most often absent.
Teeth are cut in a child, usually up to 12-14years, and by this age there are 28 of them. The most recent are 4 wisdom teeth, but this happens in adulthood or does not happen at all. Dentists do not consider the absence of wisdom teeth as a pathology.
At the rate of molars appear at such times:
- central incisors: from 6 to 8 years;
- lateral incisors: from 7 to 9 years;
- First premolars: from 9 to 10.5 years;
- second premolars and fangs: from 11 to 13.5 years;
- second molars: from 12 to 13.5 years;
- molars (third molars): after 18 years.
If molars do not appear at the right time,then you need to seek advice from a dentist. After all, this may be a sign that the tooth rudiment was not formed, and the tooth can not appear at all. Most often, the cause of this pathology is a malfunction during intrauterine formation of the teeth rudiments. It could have happened because of a mother's illness, taking antibiotics or hormones.
As a result, molars can beformed less than that required by normal anatomical development. Then the available teeth specialists shift, using the mouthguards or dental plates. For the longest time you need to protect your baby teeth so that you can put crowns or implants in their place. The same thing happens in the case of a permanent tooth loss, because the new one does not come to replace it: the molars do not change anymore.
Therefore, you need to carefully maintain hygieneoral cavity and follow the condition of the teeth: brush them twice a day, rinse the mouth with special solutions that neutralize the formation of acid on the teeth, use dental floss. It is necessary to visit the dentist once every six months to find the slightest destruction in time. After all, losing a tooth is not difficult because of vitamin deficiency, poor hygiene, hormonal changes or other stresses, and our body can not restore them independently.
