What To Do About Black Triangles Between Your Teeth
If you’ve noticed small, dark gaps forming between your teeth near the gumline, you’re not alone—and you’re not imagining things. These gaps, commonly referred to as “black triangles,” are clinically known as open gingival embrasures. While they may seem like just a cosmetic concern, they can also have consequences for your dental health.
At Blossom Dentistry, we know how much even subtle changes in your smile can impact your confidence. In this article, we’ll explain what causes black triangles between your teeth, why they happen, and how we can help restore your smile with modern, minimally invasive treatments.
Understanding What Causes Black Triangles
Black triangles appear when the gum tissue between your teeth (called the papilla) recedes or fails to fill the space beneath the tooth contacts. This can happen for a variety of reasons. Gum recession is one of the most common, especially among adults as they age or experience gum disease. When the gums pull away, those previously filled spaces become visible.
Bone loss, periodontal disease, or even overzealous brushing habits can also wear away gum tissue over time. People with triangular-shaped teeth (narrower at the gumline) or naturally thinner gum tissue may be more likely to develop these spaces. And if you’ve had orthodontic treatment, shifting teeth may create small gaps where none existed before.
Whatever the cause, black triangles can lead to issues beyond appearance—like trapping food, harboring plaque, and making teeth harder to clean.
Non-Surgical Treatment Options
For many patients, black triangles can be addressed without invasive surgery. One of the most conservative and effective approaches is cosmetic bonding. With this technique, we apply a tooth-colored resin to the sides of your teeth to close the gaps and reshape your smile. This not only improves aesthetics but also reduces places where plaque and debris can accumulate.
The results can be dramatic—and the process is typically comfortable, quick, and doesn’t require drilling or altering your natural teeth. If you're looking for a subtle yet impactful solution, cosmetic bonding is a wonderful place to start.

Prevention and Healthy Habits Matter
Once we’ve treated your black triangles, the goal is to prevent them from coming back—or getting worse. Gentle, consistent oral hygiene plays a huge role. Brushing with a soft-bristled toothbrush, flossing carefully, and using interdental brushes designed for your specific needs can all help preserve your gum tissue.
Avoiding tobacco products and staying on top of routine dental cleanings also supports gum health. And if you tend to brush aggressively or use whitening products that irritate your gums, let us know—we can recommend safer alternatives that protect your smile without compromising effectiveness.
Frequently Asked Questions About Cosmetic Bonding
What is cosmetic bonding, and how does it fix black triangles?
Cosmetic bonding is a non-invasive dental procedure where a tooth-colored resin is applied and shaped to fill in gaps, cover imperfections, and enhance the appearance of your teeth. For black triangles, we apply bonding material to the sides of your teeth to close the spaces near the gumline. It’s a great way to make your smile look fuller and more even without surgery.
How long does cosmetic bonding last?
With proper care, cosmetic bonding can last anywhere from 5 to 10 years. The material is durable but not as strong as natural enamel, so avoiding habits like biting on pens or hard foods can help extend its life. Regular dental checkups allow us to monitor the bonding and make any necessary touch-ups.
