What Is Black Triangle Correction?
Black triangles are the small, dark gaps that can appear between teeth near the gumline. While often overlooked, these spaces can be a significant aesthetic concern for patients who are otherwise happy with their smile. Black triangles can result from gum recession, bone loss, tooth shape, orthodontic treatment, or the natural aging process. Beyond appearance, they can also trap food and make oral hygiene more challenging in the affected areas.
Black Triangle Correction: Quick Facts
Quick fact | Typical answer |
|---|---|
Number of visits | 1 |
Time needed | 30 to 60 minutes per space |
Anesthesia | Usually none |
Recovery time | None |
How long it lasts | Several years; bonding can be repaired or refreshed |
These are typical ranges. Your own plan is confirmed after an examination.
Who Black Triangle Correction Is For
A black triangle forms when the gum tissue between two teeth no longer fills the space below their contact point. Correction is cosmetic, but it also removes a spot where food packs and plaque builds up.
Dark gaps that appeared after braces or aligners
Spaces that opened after gum recession or gum treatment
Food that catches between the same teeth after every meal
Triangular teeth that touch only at the tips
Healthy, stable gums with no active gum disease
Black Triangle Correction at Bensonhurst Dental Care
At Bensonhurst Dental Care, black triangle correction is performed by Dr. Marina Rubinshtein using advanced composite bonding techniques. The process involves carefully layering tooth-colored composite resin into the spaces between the teeth, filling the triangular gaps while maintaining a natural tooth contour. Dr. Marina’s artistic precision ensures the corrections blend seamlessly with the surrounding teeth, restoring a smooth, uniform appearance to the smile.
What to Expect, Step by Step
The procedure is minimally invasive and typically completed in a single visit. Because composite resin is applied directly to the tooth surfaces without the need for drilling or significant preparation, the natural tooth structure is fully preserved. Patients see immediate results with little to no discomfort, making black triangle correction one of the most straightforward yet impactful cosmetic treatments available.
Evaluation. We measure the gaps, check gum health and confirm the gums are stable.
Shade matching. Resin is matched to each tooth.
Isolation. A thin clear matrix is placed between the teeth to shape the new contour.
Bonding. Resin is layered to widen the tooth near the gumline and close the space.
Polish and floss check. The area is polished and we confirm floss passes cleanly.
Ways to treat black triangles
Approach | How it works | Best for |
|---|---|---|
Composite bonding | Resin reshapes the sides of the teeth | Most small to moderate gaps |
Porcelain veneers | Porcelain changes the full shape of the teeth | Gaps plus color or shape concerns |
Orthodontics | Teeth are moved closer and reshaped | Gaps caused by tooth position |
Gum grafting | Tissue is added where gums have receded | Selected cases of recession |
A black triangle is a small space with a large effect on a smile. Closing it is often the least invasive cosmetic change we make.

Related Treatments
For patients whose black triangles are part of broader cosmetic concerns, such as uneven spacing, worn edges, or discoloration, Dr. Marina may recommend combining correction with other treatments like porcelain veneers for a more comprehensive transformation. Each treatment plan is tailored to the individual, ensuring the final result is cohesive, natural, and aligned with the patient’s vision for their smile.
Cost and Insurance
Cosmetic treatment is planned tooth by tooth, so the fee depends on what you choose to change. You receive a written estimate after your consultation and before any treatment starts.
What affects the cost
The number of teeth being treated
The material chosen, such as composite or porcelain
Any preparatory care needed first, such as a cleaning, whitening or gum contouring
Laboratory work for custom restorations
Treatment done for appearance alone is usually not covered by dental insurance. Restorations that also repair damage may be covered in part. Our team can check your benefits and explain your options before treatment begins.
