By about three years old, the formation of the roots of milk teeth in children ends. But then they gradually "resolve" from the "onset" (pressure) of the permanent teeth, the temporary ones fall out, and in their place
indigenous ones begin to erupt.
When a child has milk teeth, mounds or edges of the cutting constants are visible in the holes. Normally, after the eruption of all the milkmen, there should be no gaps between them (cracks appear and expand as the jaw grows). This is logical: after all, permanent teeth are larger in size than temporary ones, and they need more space (otherwise they will grow curved). The lack of space may be indicated by the late appearance of a permanent tooth in place of the milk. In such cases, the help of an orthodontist is needed, which through special procedures will "facilitate" the teething.
During the period when the child has milk teeth and their roots are resorbed, the pulp is replaced by granulation tissue, which is involved in the process of dissolution of the roots. The treatment of temporary teeth is fundamentally different from the treatment of permanent, has its own specifics.
A little at different times, but all parents have a question about how old milk teeth fall out. Usually this process begins at the age of 6 and ends by 12-13 years.
First, as a rule, sixth teeth fall out, then the central and lateral incisors, later fourth, fangs, fifth, seventh, then eighths. The final formation of the "root system" of permanent masticatory organs occurs by 10-15 years, and the apparatus itself - by 15-18 years.
Parents should understand: the period when a child has deciduous teeth is a small psychological test, although the process itself is almost painless, only a slight increase in temperature is possible. However, since the timing of tooth changes is almost the same for all children, peculiar competitions often arise among peers on this basis: “Who will“ update ”the mouth faster” and children begin to “accelerate” the process by loosening and removing milk teeth on their own. This cannot be done! Such an intervention is fraught with infection and the possibility of breaking a tooth (the consequences can be extremely unpleasant, and sometimes even dangerous). Therefore, when a child has milk teeth, it is necessary to talk with him and explain that there is no place for any amateur activity, only then new ones will grow beautiful, smooth and healthy. The only exceptions are cases when the “milkman” is already really “hanging by a thread” (then you can remove it with your own but clean hands).

If the child complains about the inconvenience, and the tooth just staggers, you must consult your dentist for the most safe removal. Thus, the period when milk teeth fall out in children should not be a cause for particular concern, from the side of parents only a timely explanation of the situation and a little control are required.
