What are black triangles?

The black triangle teeth are the spaces between the teeth and gum line that easily gets noticed when the mouth is opened. This occurs for the person having periodontal or gum disease mostly. These black triangles start appearing black eventually due to food trapping in it. After a certain period, it starts developing plaque and tartar on the teeth. Black triangles degrade the smile of the person.

What are the causes of the black triangles?

The primary cause of the black triangles is the presence of a gap between teeth. Some of the gum problems and other oral health issues are responsible for it.


Here are some of the reasons for the development of black triangles:

1. Bone loss

Some loss of the bone at the base of the tooth can cause problems like black triangles. The loss of the bone further causes receding of the gum tissue. It eventually leads to the formation of the black triangles.

2. Recession of the gums gum recession

The gums can recede due to several reasons that can develop bacteria, plaque, and tartar. This can cause the gap between the teeth along with cavity development.

3. Diverging tooth roots

Different types of dental or Orthodontic treatment can cause the roots to diverge. This leads to the increase in the gap between teeth cause a black triangle.

4. Improper dental habits

Improper dental habits like irregular brushing, flossing, etc. can lead to easy plaque development in the space between teeth. This space can eventually grow on increasing.
