When the milk teeth change to permanent
The growth of infant teeth in children begins approximately inSix months, some of this process starts earlier (4.5 months) or later (9-10 months). By the first year of life, the child already has four pairs of teeth. At the age of two or three years the child can count 20 teeth. Erection of primary teeth occurs in a certain sequence and brings anxiety to the baby.
By the age of six, the child starts to growTeeth, coming to replace dairy. This process lasts until about thirteen years, and for some it drags on to fifteen. The structure of milk teeth is not much different from permanent teeth, but milk enamel is thinner and the crown consists of less hard tissue. Primary teeth have a root that is well developed, but it has the property of resolving as the permanent tooth grows.
The process of changing teeth
Erection, and also change of milk teethIs carried out gradually and systematically. Before the beginning of this phenomenon, gaps appear between the teeth, or so-called trema. The appearance of trembles is a normal process, because the child's jaw becomes larger as it develops. The absence of cracks can indicate a disruption in the development of the maxillofacial apparatus and this can contribute to the crooked growth of permanent teeth.
Milky teeth change in suchSequences; By the age of six or seven, the first chewing molars (molars) appear, by nine years the central incisors, the first pre-molars (premolars) appear to nine to ten, and by the eleven years the fangs, the second premolars to eleven to twelve years and the second molars at thirteen. And the very last (third molars) grow to 25 years, they are called "wisdom teeth".
It is necessary to ensure that the child does not touch loose teeth and does not bring mud from the hands to the mouth, since this can lead to inflammation.
Necessary actions for changing dairy teeth
The replacement of primary teeth by permanent teeth isA natural physiological phenomenon. For the successful course of this process, you must first take care of this: you need to protect the young teeth of children, limit the consumption of sweet, to teach the child to regular and thorough cleaning of teeth and, if necessary, do not delay with treatment at the dentist. There are parents who have the erroneous opinion that milk teeth do not need treatment if the child does not experience toothache, because they eventually fall out. But a sick tooth is a hotbed of infection and can be a carrier of caries to a permanent tooth, even though it has not yet appeared on the gum surface. It is advisable not to delay with the treatment of an infected tooth, otherwise there will be problems with changing teeth to permanent teeth. If there was already a root filling, then the process of resorption proceeds more slowly and the milk tooth interferes with the normal growth of the permanent, so this requires the removal of milk. Why is it necessary to fill, and not remove, a dairy carious tooth? If the milk tooth is removed before the due date, the adjacent teeth move toward the removed tooth, which can lead to a bite defect.
With the beginning of the period of changing primary teeth, you need to go to the dentist, even if the child has no complaints. Timely prevention of the disease is easier than eliminating the neglected pathology.
It happens that a four-year-old child complains of teeth - this is not the norm. The cause may be caries, so it should be shown to the dentist.
