What Are Black Triangles Between Teeth?
Black triangles are small dark spaces that appear near the gumline between two teeth. Dentists and orthodontists often refer to these spaces as open gingival embrasures. They occur when the gum tissue between teeth no longer completely fills the space below the contact point. Black triangles can affect smile aesthetics and may also create areas where food and plaque become trapped.
Have you ever noticed a triangular gap between your tooth and gum line? That gap is commonly called a “black triangle”, or to us dental professionals, “open gingival embrasures.”
And about one-third of adults have black triangle teeth!
Most reasons behind black triangles are not considered unhealthy or problematic; however, they do throw off the balance of your smile and can cause embarrassment. Luckily, there are treatments available to correct this condition!
What Causes Black Triangles?
Several factors can contribute to black triangles, including:
- Gum recession
- Periodontal disease
- Bone loss around teeth
- Natural tooth shape
- Aging
- Previously crowded teeth
- Orthodontic tooth movement that reveals existing spaces
Many patients are surprised to learn that orthodontic treatment does not necessarily create black triangles. In many cases, treatment simply reveals spaces that were previously hidden by crowding or overlapping teeth.
Can black triangles be prevented?
You cannot always avoid black triangles. In fact, some spacing between your teeth is natural and can be helpful for flossing.
When you have black triangles, it’s crucial to stick to a strong oral hygiene routine, including brushing, flossing, and using mouthwash. Plus attending all of your dental cleaning appointments! Because visiting your dentist regularly is incredibly important to monitor your gum and dental health. Doing all of this will keep your smile bright and healthy.
Can braces cause black triangles?
The belief that black triangles are caused by orthodontic treatment, such as braces or Invisalign, is false. Orthodontic treatment doesn’t cause black triangles; it simply exposes them.
When your teeth are aligned, receding gums or lack of gum tissue between the teeth can expose these black triangles.
If you visit a highly-qualified orthodontist, you do not have to fear gum loss or black triangles due to orthodontic treatment. Especially if that orthodontist is dual-trained in periodontics as well – like Dr. Matsumoto!
As with every treatment plan Dr. Matsumoto creates, the full harmony of your smile is considered – from your teeth, gum tissue, to your bone structures. If any periodontal problems are spotted during your first orthodontic exam or if any pop up during your treatment, Dr. Matumoto is equipped to address them and help balance the beauty of your smile.
Can Invisalign or Braces Fix Black Triangles?
In many cases, yes.
Orthodontic treatment can reposition teeth to improve how they contact each other. By changing tooth alignment and contact points, braces, Invisalign, or Brius may reduce the appearance of black triangles and improve smile aesthetics. Some cases may also benefit from Interproximal Reduction (IPR), which carefully reshapes teeth to allow them to fit together more naturally.
How do orthodontists get rid of black triangles between teeth?
If you notice a small triangle between your teeth, we can provide orthodontic treatment to close it!
At Matsumoto Orthodontics & Periodontics, Dr. Matsumoto can treat black triangles using Interproximal Reduction (IPR), braces, Brius, or Invisalign®.
- Braces, brius, or Invisalign
Dr. Matsumoto may recommend treatment with braces, brius, or Invisalign to reduce the appearance of black triangles. The treatment consists of applying gentle, consistent pressure to specific teeth to encourage movement toward healthy alignment – effectively eliminating black triangles between teeth!
- Interproximal Reduction (IPR)
Interproximal Reduction is a technique performed by experienced orthodontists to close black triangles. The treatment is performed by hand, using flexible diamond coated strips that are worked back and forth between your teeth. A tiny part of the tooth enamel is trimmed, which will allow your teeth to be pushed closer together. Thus reducing the black triangles and spaces your gum needs to fill between teeth.
Why Dr. Matsumoto’s Orthodontic and Periodontal Training Matters
Black triangles often involve both tooth positioning and gum health. Because Dr. Matsumoto is trained in both orthodontics and periodontics, patients benefit from a comprehensive evaluation of the teeth, gums, and supporting bone structures. This allows treatment recommendations to address the underlying cause rather than simply masking the appearance of the space.
Let Dr. Matsumoto close your black triangles!
We understand the presence of black triangles can make you feel self-conscious about your smile. We want you to feel confident during and after your orthodontic treatment. Please don’t hesitate to reach out to us with any questions!

Frequently Asked Questions About Black Triangles Between Teeth
What are black triangles between teeth?
Black triangles are small dark spaces near the gumline that occur when the gum tissue between teeth does not completely fill the area below the contact point between teeth. They are also known as open gingival embrasures.
Can orthodontic treatment fix black triangles?
Yes. Depending on the cause, orthodontic treatment may reduce or eliminate black triangles by improving tooth alignment and contact points. Some patients may also benefit from IPR or periodontal treatment.
Does Invisalign help with black triangles?
Invisalign can help improve black triangles by moving teeth into more favorable positions. In some cases, additional procedures such as IPR may be recommended to achieve the best result.
Do braces cause black triangles?
Braces do not usually cause black triangles. Orthodontic treatment may reveal spaces that were previously hidden by crowded or overlapping teeth.
What is IPR and how does it help black triangles?
Interproximal Reduction (IPR) is a procedure that removes a very small amount of enamel between selected teeth. This allows teeth to move closer together and can help reduce black triangles.
Are black triangles bad for oral health?
Black triangles are often a cosmetic concern, but they can also trap food and plaque, making oral hygiene more difficult and increasing the risk of gum inflammation.
Can gum recession cause black triangles?
Yes. Gum recession is one of the most common causes of black triangles because it reduces the gum tissue that normally fills the space between teeth.
Who is a candidate for black triangle treatment?
Anyone bothered by the appearance of black triangles or experiencing food trapping between teeth may be a candidate. A consultation can determine whether orthodontics, IPR, periodontal treatment, or a combination approach is most appropriate.
