The laying of teeth and the formation of their primordia begins in the child at the 7-8th week of embryonic development, and hard tissues of the teeth are formed at the end of the 16-17th week. Therefore, all children are born with shaped teeth that are waiting for their development to appear from the gums.
This usually happens when the baby is six months old, but there are cases of both earlier and later teething. When a child’s teeth are cut, it brings a lot of inconvenience not only to himself, but also to his parents - after all, the baby's health worsens, he becomes restless, capricious, eats worse, sleeps worse and constantly asks for pens. But these are temporary signs that pass over time.
Normally, a child’s teeth are always cut in pairs, in a certain sequence. This helps to form the correct bite. The baby teeth in full appears in the baby by two and a half years. After this comes the period of "dental lull."
Permanent teeth in children begin to appear at the age of 6-7.5 years: milk teeth begin to fall out, and molars appear in their place. Most often, this process begins with the lower incisors. Do not worry if milk teeth have fallen out, and permanent ones do not appear within a few months after that. Go to the dentist's office to see how the rudiments of the molars are located, how they are formed and when they are ready to erupt.
At first, nature determined the replacement of incisors: upper and lower. It is no accident that the child’s teeth are cut in such a clear sequence. The incisors grind the most in the process of biting and chewing, and therefore they change to permanent ones very first. Then the same sequence is observed in which milk teeth appeared.
When a child’s molars are cut, he experiences it much more calmly than the process of the appearance of the first milk. Temperature and pain are most often absent.
Teeth are cut in a child, usually up to 12-14 years old, and by this age there are 28 of them. The last 4 teeth of wisdom appear, but this happens in adulthood or does not occur at all. Dentists do not consider the absence of wisdom teeth as a pathology.
Normally, molars appear at such times:
- central incisors: from 6 to 8 years;
- lateral incisors: from 7 to 9 years;
- The 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 consult a dentist. After all, this may be a sign that the tooth rudiment has not formed, and the tooth cannot appear at all. Most often, the cause of this pathology is a failure during intrauterine formation of the tooth buds. This could be due to the illness of the mother, taking her antibiotics or hormonal drugs.
As a result, fewer molars can be formed than normal anatomical development requires. Then the specialists move the existing teeth using mouth guards or dental plates. For the longest possible time, you need to take care of milk teeth so that crowns or implants can be put in their place. The same thing happens in the event of the loss of a permanent tooth, because it is not replaced by a new one: molars no longer change.
Therefore, it is necessary to carefully maintain oral hygiene and monitor the condition of the teeth: brush them twice a day, rinse your mouth with special solutions that neutralize the formation of acid on your teeth, and use dental floss. Be sure to visit the dentist once every six months in order to detect the slightest damage on time. After all, losing a tooth is not difficult at all due to vitamin deficiency, poor hygiene, hormonal changes or other stresses, and our body will not be able to restore them on its own.
