Those small dark gaps near your gum line can quietly change how you feel about your smile. Known as black triangles, they form between teeth where healthy gum tissue once filled the space. The good news? You don’t have to live with them, and you don’t need invasive cover-ups to fix them. At Karen E. Williamson, DDS, PA in Rockwall, Texas, we use a modern, conservative approach to restore a fuller, healthier-looking smile.
What Are Black Triangles and What Causes Them?
Black triangles, those dark gaps between teeth near the gumline, are easily corrected by Karen E. Williamson, DDS, PA, restoring a seamless, confident, and naturally beautiful smile
Black triangles, or open gingival embrasures, are the gaps that appear between teeth when the gum tissue doesn’t fully fill the area. They tend to show up most often between the front teeth, where they’re easy to notice.
Several factors can lead to them:
- Gum recession: When gums pull back, the space between teeth opens up.
- Bone loss: Reduced bone support changes how gum tissue sits around your teeth.
- Tooth shape: Some teeth are naturally more triangular, leaving narrow contact points and wider gaps below.
- Orthodontic treatment: Shifting teeth into new positions can reveal small spaces.
- Aging: Over time, gum tissue naturally thins and recedes.
Even with excellent brushing and flossing habits, these gaps can develop. They aren’t always a result of poor care.
Are Black Triangles a Sign of Gum Disease?
Not necessarily, but they shouldn’t be ignored. Black triangles can be a side effect of past gum disease, since infection damages the gum and bone that support your teeth. In other cases, they have nothing to do with disease at all and simply reflect your tooth shape or natural changes over time.
The concern goes beyond appearance. These open spaces trap food and bacteria, which can make daily cleaning harder and raise your risk of decay and gum problems. That’s why it’s worth having them evaluated.
When to seek care: If you notice bleeding gums, tenderness, or growing gaps, schedule a visit. Dr. Williamson can determine the cause and confirm whether your gums are healthy before recommending treatment.
What Is the Bioclear Matrix?
The Bioclear Matrix is a modern technique that fills in black triangles while protecting the natural structure of your teeth. Rather than removing healthy enamel, it builds up the space using a specially designed clear matrix and warmed, tooth-colored composite. The result is a smooth, seamless contour that hugs the gum line and closes the gap.
We see this as a holistic, artistic approach to your smile. Instead of cutting down teeth, we work with what you already have to create natural-looking results.
Myth vs. reality: Many people assume veneers are the only solution. In truth, veneers often act as a bandaid that covers the problem and requires reshaping otherwise healthy teeth. The Bioclear Matrix takes the opposite path, restoring your smile without sacrificing your tooth’s natural integrity.
The benefits are clear:
- Conservative, no-drill approach in many cases
- Durable, stain-resistant results
- Easier-to-clean spaces and improved gum health
- A confident, full smile that looks like you
