Although receding gums can show off the unattractive cementum of your tooth roots, it’s often something else that you notice first: black triangles that begin to appear between your teeth. These triangles can be unsightly, but you don’t have to live with them–they can be corrected to give you a renewed, more attractive smile.
What Causes Black Triangles between Teeth
The space of your smile should be largely filled with your teeth and gums. The high contrast between your lips, gums, and teeth is designed to draw the eye and create an attractive appearance. But when your teeth and gums don’t fill that space, what’s left is negative space, black triangles that show through into your mouth.
For many people, black triangles are developmental. They are one consequence of crooked teeth, crowded teeth, or teeth that are too small.
Receding gums are the most common cause of developing black triangles. As your gums begin receding, among the first things to go are the interdental papilla, the parts of the gums that fill up the space between your teeth. As these papilla go, they leave an empty space behind.
Other times, black triangles can be caused by imperfect cosmetic dentistry work. This can include over-aggressive gum recontouring as well as porcelain veneers or dental crowns that are not properly sized or placed, leaving space below or around them.
Correcting Black Triangles
If you are unhappy with black triangles in your smile, we will first try to identify the cause of your black triangles. If your black triangles are due to crooked teeth or small teeth, orthodontics, dental veneers, and dental crowns can all be used to fill up the space.
But if your black triangles are due to receding gums, gum rejuvenation can fill in the gaps in your smile so you can share it with confidence again.
