When the gum can't completely cover the gap between the neck and two teeth, a black empty triangle will appear between the two teeth, which is professionally called the abduction gap of the gum, commonly known as the black triangle!

Will there be a "black triangle" after orthodontics? Many people mistakenly think that there will be a "black triangle" after orthodontics, but it is not. Whether there will be a "black triangle" after orthodontics is related to the following situations:

0 1. periodontitis

Periodontitis is one of the main reasons for the formation of the "black triangle" of teeth, which will lead to gingival atrophy and alveolar bone absorption, and lead to excessive exposure of root and the emergence of the black triangle.

02. The correction force is too great.

The black triangle in the correction process is caused by occlusal trauma or excessive correction force, which causes gingival atrophy. EBrace's customized correction force is unlikely to have such a problem. Even if the teeth are removed, it will generally recover slowly.

03. Periodontal biotype

Thick periodontal biological bone tissue is thick and dense, gingival papilla is wide and flat, blood supply and biological tissue memory are good, and gums are not easy to shrink. On the contrary, thin periodontal biotypes often have scalloped bone morphology, narrow gingival papillae, and are prone to permanent recession, so black triangles are more likely to appear after correction.

04. Crowded teeth

When the teeth are not crowded, the gums are shrinking. When the teeth are arranged neatly, there is a "black triangle" between the teeth. In fact, it is not caused by wearing braces, but the state of the gums themselves.

05. Age

With the increase of age, the height of gingival papilla decreases by 0.0 12mm every year, and the incidence of black triangle will also increase.

06. Toothpick

Frequent and excessive use of toothpicks can easily destroy gingival tissue and cause a black triangle.
