Black triangles between teeth

Metro reported on these black and brown gaps that wedge between two teeth, typically at the bottom of each teeth. Not only is it unsightly, but some people can find it appearing even when they think they have been doing the most for their dental hygiene.

The report quotes Dr Abdul Azizi, Principal Dentist of Harley Private Dentist Clinic, who shares that these black triangles do not by default, mean something horrible is going on with your teeth. It can however, indicate dental issues.

The shape and size of your teeth could also be responsible for these black gaps Caroline LM

He is quoted as saying,

Black triangles between your teeth are not inherently dangerous but may be associated with oral health concerns, like gum disease or gum recession.
‘They are not necessarily a sign of poor hygiene, as various factors, including genetics and tooth shape, can contribute to their development.
However, they can trap food particles and impact oral hygiene and aesthetics, which may warrant dental attention for cosmetic or preventive reasons.

Reasons for these black triangles between teeth

As per Metro, one of the reasons for these dark specks could be gum recession, which ‘occurs when the gum tissue that normally covers the roots of teeth begins to pull away, exposing part of the tooth’s root.’ This can appear as a black gap between teeth.

Loss of bone support as a result of periodontal (gum) disease can also lead to gums pulling away from teeth, creating gaps.

The shape and size of your teeth could also be responsible for these gaps. Even age and the resulting changes in your body could lead to these black triangles.

Orthodontic treatment, like braces or aligners, are also responsible for it in some cases.

Good dental hygiene, no smoking, and gentle flossing can help you keep things in shape. If you are affected by it, you should visit a dentist to determine a solution for it.
