The most effective period for orthodontic treatment is considered to be the period from 10 to 12 years, at the time of the final formation of a permanent bite.
At this time, almost all teeth are already present, on the other hand, the bone tissue of the jaws is still immature and malleable, and the dentition moves with braces very easily.
The above information does not mean that the child should not be shown to the orthodontist before this date.
In fact, the first visit to the dentist orthodontist should be as early as 2-3 years old.
