A black triangle is the space occurring between two teeth known as
an embrasure, which is not completely filled by the gum tissue. This gap
between gum and teeth creates the triangular space and it appears black as the darkness of the mouth is visible behind the
teeth. A black
triangle is not just an aesthetic problem but food and plaque accumulates,
further plaque accumulation causes cavities and other severe problems like
dental abscesses, etc.
Causes of black triangle:
