When looking at a child, between the ages of 5 and 12, one should always pay attention to the position of the upper teeth at rest.
The lips should be closed and the teeth should not be visible.
In some malocclusions, the lower lip tends to slip behind the upper incisors and in that way further stimulates them to move outward.
This condition can be a sign of different problems, concerning the skeletal structure or just the teeth. When it comes to the treatments, they may be different at different times.
However, in this case, it is strongly recommended to receive an specialist’s evaluation..
