Why do many black people have a crack between their front teeth?

There may be cracks between many black front teeth for the following reasons:

1. The study of black teeth pointed out that the causes of the gap between front teeth may include labial frenum's width, periodontal disease, middle teeth, poor bone and forward inclination. These factors may cause the teeth not to approach normally.

2. It may be due to the low attachment of the upper lip frenum. Ligament of upper lip refers to the fibrous tissue connecting lips and gums. If this tissue is too thick for the two front teeth to be close together, a gap will be formed between the front teeth.

3. It may be due to the premature eruption of the upper central incisor, and the tooth germ of the lateral incisor may press the root of the central incisor, resulting in the gap between the incisors.

Genetic factors are also a possible reason. For example, a person's parents have incisor gap, so he may also have incisor gap.

The above are only some possible reasons, and do not represent the reasons for the formation of cracks in all black front teeth. Everyone's situation is unique, and it is necessary to check and diagnose according to personal conditions to determine the cause. If you know more about this problem, please consult a professional to get a more accurate explanation.
