BLACK TRIANGLES

Black triangles between teeth

Black triangles are the dark spaces that can appear between teeth near the gumline. They are common, can affect the appearance of a smile and may also trap food. For suitable cases, Bioclear offers a conservative way to reshape tooth contours and close these spaces.

UNDERSTANDING THE CONCERN

What are black triangles?

Black triangles are open spaces between adjacent teeth, usually near the gumline. They can become more noticeable as gum levels change, when teeth move, or because of the natural shape of the teeth. Many patients first notice them visually, although food trapping can also be a concern.

Gum recession
The gum tissue between the teeth may reduce or recede.

Bone support
Changes in bone support can affect the gum tissue between teeth.

Tooth shape
Triangular tooth shapes can leave more visible space near the gumline.

Tooth movement
Spaces can become visible following orthodontic movement or relapse.

WHY TREAT THEM?

Why patients choose to close black triangles.

Smile appearance
Reduce dark spaces and create a more continuous smile.

Food trapping
Broader contacts may help reduce spaces where food collects.

Smoother feel
Refined tooth contours can feel smoother between the teeth.

After orthodontics
Some patients notice black triangles after tooth movement.

THE BIOCLEAR APPROACH

How Bioclear may help close black triangles.

Rather than automatically moving to crowns or veneers, Bioclear can be used in suitable cases to add composite around the tooth and reshape the contact area more conservatively.

The aim is to create smooth, natural-looking contours while preserving healthy tooth structure wherever possible.

How the Bioclear Method works

What the clinician is trying to achieve

• Broaden the contact area between teeth

• Close or reduce the visible dark space

• Create smooth contours that are easier to maintain

• Keep treatment as conservative as appropriate

YOUR APPOINTMENT

What treatment may involve.

1. Consultation & assessment
Your clinician looks at the teeth, gum levels, spacing, bite and what you would like to improve.

2. Conservative restoration
A Bioclear matrix and composite may be used to reshape the tooth and close the space.

3. Finish & polish
The restoration is refined and polished to create a smooth final contour.
