13 years old front teeth have cracks?

In fact, most parents don't have to worry too much about this. When the child's upper teeth just erupt, the two crowns will look like a figure of eight, which is a normal transitional state. That's because the roots of the upper incisors are squeezed by the lateral tooth germs, resulting in deviations and gaps.

Therefore, after the teeth on both sides of the front incisors, that is, the lateral incisors and canine teeth (also called tiger teeth) erupt, the gap in the middle can slowly disappear by itself, and the crooked teeth will be adjusted and aligned.

In addition, there are some special circumstances that will lead to a large gap between the front teeth (more than 3 mm) and need to be dealt with:

1. Children have bad habits, such as biting pencils and sucking fingers. Or sleep with your mouth open at night due to nasopharyngeal diseases, which will cause the front teeth to "buck teeth" and the teeth will become larger and inclined;

2. Some children's two front teeth will have abnormal supernumerary teeth, or the gap between the front teeth is too large due to the low adhesion of the upper lip ligament, which affects the normal closure of the gap between the two front teeth. It should be checked and treated in time.
