Triangles usually come up when discussing shapes with children or even in math and design projects. Most people don’t associate them with dental health. An increase in patients with dental black triangles, however, has led to more and more patients talking about it with their dentist.

What Are Dental Triangles?

As the name suggests, dental black triangles are small gaps that appear between the teeth in the shape of small triangles. The medical term for this is open gingival embrasures and typically affects the front teeth on the top and bottom.

As we age, our gums begin to recede, causing the bottom of the tooth to become exposed. Since our teeth taper inward (like an upside-down triangle) towards the root, the recession of the gums can cause small triangles to appear in the space that has developed between the teeth. For some patients, this may not necessarily be a sign of poor dental health, but it can leave the tooth at greater risk for food particles to get stuck. Plus, for many, it can make them feel self-conscious about their smile.

What Does This Mean For My Oral Health?

While the appearance of dental black triangles is not necessarily a cause for immediate concern, it is important to talk to your dentist about what could be causing your gums to lose tissue. In patients who are only showing mild to moderate signs of the triangles between the teeth, it can simply be a side effect of aging, as our bodies tend to regress as we age. However, for patients who are exhibiting more severe signs of these dental triangles, it may be a sign of a more in-depth dental issue.

For example, dental black triangles are especially common in patients who suffer from some form of periodontal disease. Additionally, gum recession in younger patients may be a sign of improper brushing technique, as they may be degenerating if you are aggressively cleaning your teeth.

All in all, there is no way to determine if this is a sign of a more deep-rooted issue or a simple fix, like relearning how to properly brush, can prevent the triangles from becoming bigger. Talking to a dentist can also help determine what the underlying cause is and how best to treat it.

These dental black triangles are often a result of deficiency, gum recession or a loss of papilla. They’re very common in patients with periodontal disease.

Treating Open Gingival Embrasures

The discovery of these black triangles can be disheartening for many patients. It can cause them to feel uncomfortable smiling, laughing, or even eating – as food is more likely to get caught between the teeth when these triangles are present. Thankfully, it is a treatable condition and there are various options to help reverse the appearance of these triangles and help stop them from becoming deeper.

Can I Prevent Black Triangles From Forming?

While there is no way to specifically prevent dental triangles, they are often linked to poor oral health, so taking good care of your teeth is a great place to start. Dentists might sound like broken records, but they have a point, after all. Brushing your teeth twice a day is not enough to prevent oral diseases! In fact, you should be brushing and flossing twice a day, plus rinsing your mouth, brushing your teeth, and practicing good eating habits. Visiting your oral health care provider twice a year is also an important part of keeping your mouth healthy and happy and reducing your risk of developing unsightly dental triangles.
