Have you ever noticed a gap between your teeth? This little gap is called a black triangle gingival embrasure, and it’s pretty common. It’s not a cause for alarm, but if you want to get rid of the gap, there are ways to do so. Let’s take a closer look at the black triangle or gingival embrasure between your teeth, the causes, and how you can get rid of them.

What is a black triangle?

Black triangles are gaps between two teeth that are caused by gum recession. The area between the two teeth becomes exposed, leaving an open space that appears dark because of the shadows cast by overlapping teeth above it. Black triangles can be found anywhere in the mouth, but they usually appear between the front teeth or canine teeth because these are most exposed when you smile.

What causes black triangles?

Several factors may contribute to forming black triangle/gingival embrasures between your teeth. Some of these include:

  1. Poor dental hygiene habits – if you don’t brush and floss regularly, plaque and bacteria can accumulate around the gum line and cause receding gums. This will create a larger gap between your teeth.
  2. Malocclusion – when the upper and lower jaws don’t fit together correctly, it causes misalignment, which can lead to a black triangle between your teeth.
  3. Misaligned bite – when there is an imbalance in the bite pressure exerted on different parts of the mouth, this can cause one side of the jawbone to be higher than the other, leading to gaps forming over time.
  4. Genetics – some people are simply more prone to developing black triangles due to their genetics.
  5. Aging – as we age, our gums tend to recede slightly due to bone loss resulting in more pronounced gaps between our teeth.
  6. Tooth Loss – losing a tooth leaves a gap in your smile which can cause other nearby teeth to shift into the empty space resulting in a black triangle forming around it.

How can I get rid of the gaps?

Your dentist may suggest several options for closing those gaps depending on their size and shape. For small gaps, a bonding material may be used to fill in the space and give your smile a more uniform appearance. Porcelain veneers are another option—these thin porcelain shells will cover up any unwanted spaces for an instantly improved smile line! If your gums have been damaged due to periodontal disease, then you may require surgical treatment such as soft tissue grafts or bone augmentation.
