Black Triangles
What is a black triangle:
A black triangle, also known as an open gingival embrasure, is a term used in dentistry to describe a space or gap between the base of two adjacent teeth near the gumline. This triangular-shaped space appears as a dark or shadowy area, which can be more noticeable when smiling or speaking.
Black triangles can be a cosmetic concern for some individuals as they can affect the appearance of the smile. Additionally, they may contribute to difficulties in maintaining oral hygiene as food particles and plaque can get trapped in the gaps, leading to potential gum inflammation and dental issues.
What causes black triangles?
- Gum recession: When the gums recede or pull back from the teeth, the triangular space can become exposed.
- Bone loss: Loss of bone support around the teeth can cause the gums to pull away and create black triangles.
- Tooth shape and size discrepancies: If the teeth are naturally small or have irregular shapes (usually triangular), there may be gaps between them.
- Orthodontic treatment: In some cases, orthodontic treatment can result in the formation of black triangles due to changes in tooth position and alignment. This typically occurs after correction of moderate-severely crowded teeth.
How can you treat black triangles?
Dr. Yi specializes in treating black triangles and small gaps with composite resin (dental bonding). This advanced technique involves no drilling and usually no anesthetic. It is an additive procedure using composite resin to alter the shape of your teeth and close black triangles and gaps.
Below are some of the options for treating black triangles:
- Dental bonding: Using tooth-colored composite resin, a cosmetic dentist can fill in the space to minimize the appearance of black triangles. Oftentimes without anesthetic and without removal of tooth structure.
- Porcelain veneers: Custom-made porcelain veneers can be placed on the affected teeth to close the gaps and improve the overall aesthetics. Usually requires a small amount of tooth structure removal on the front surface of the tooth.
- Orthodontic treatment: In some cases, orthodontic treatment, such as braces or clear aligners like Invisalign, may be recommended to reposition the teeth and reduce the size of black triangles.
