What Causes Black Triangles?
Black triangles, or open gingival embrasures, are most often caused by the loss of gum tissue between the teeth (known as the interdental papilla). Several factors can lead to this condition:
- Gum recession due to aging, periodontal disease, or brushing trauma
- Orthodontic treatment that repositioned teeth and left open spaces
- Natural anatomy or narrow tooth shapes
- Bone loss, particularly in patients with a history of periodontal disease
Not only do these spaces detract from your smile’s symmetry, but they can also create hygiene challenges. Food particles and plaque may accumulate in these areas, increasing your risk of gum inflammation or decay.
The Bioclear Solution
Bioclear offers a minimally invasive way to close these gaps and enhance both appearance and oral health. We use specially designed matrices that fit around your teeth. A warm, flowable composite resin is placed inside the mould, filling the space naturally. Once cured and polished, the result is seamless and strong.

Step-by-Step Process
Evaluation and cleaning
We assess your teeth and gums, then perform a thorough cleaning and scaling to remove any buildup


Matrix selection
Matrices are selected based on tooth shape and space dimensions
Composite injection
The resin is applied and heated for a smooth flow, then cured with a light


Finishing and contouring
The final step involves polishing and shaping the resin for a natural feel and look
What Makes This Different from Veneers?
Unlike porcelain veneers, Bioclear:
- Requires no removal of enamel
- Is reversible and repairable
- Can be completed in one visit
- Is significantly more affordable
