What Is A Dental Black Triangle? Causes And Treatments

A black triangle is not just an aesthetic problem. As the BDJ article explains, food particles and plaque can accumulate in the gap. The Mayo Clinic notes that plaque accumulation can lead to cavities, as well as more severe oral problems, such as dental abscesses. That's why it's important to get an assessment from a dental professional if you notice these spaces between your teeth.

Because of the complex nature of the dental black triangle, treatment often requires an interdisciplinary approach. This means that your family dentist may need to coordinate treatment for this condition with various specialists — most likely a periodontist or an orthodontist.

According to the BDJ article, management of black triangles may involve:

• Surgical approaches: There are a variety of surgical techniques that can help to preserve the gum tissue between teeth.
• Tissue engineering: Tissue engineering involves the injection of regenerative cells to help regrow the missing gum tissue.
• Tissue volumizing: Similar to the technique used for facial tissue regeneration, tissue volumizing uses hyaluronic acid to reduce black triangles.
• Tooth or restoration reshaping: Altering the shape of the teeth through cosmetic recontouring, bonding or fabricating new crowns or veneers can help to eliminate black triangles.
• Pink restorative materials: Pink shades of porcelain and composite materials can sometimes be used to hide or reduce black triangles.
• Gingival veneers: A removable gingival veneer or mask is a gum-colored acrylic or silicone device that can be used to cover black triangles. This can be a cost-effective way of temporarily covering the spaces between teeth, but it requires excellent oral hygiene and manual dexterity.
• Orthodontic treatment: Although orthodontic treatment can sometimes have the unintended consequence of creating black triangles, it can also help to eliminate the problem in certain cases by repositioning teeth and their roots.

The best way to prevent black triangles from forming between your teeth is to take care of your teeth and gums by brushing twice a day, flossing once daily and visiting your dentist for checkups regularly. While there's no guarantee that you won't see black triangles at some point, you can rest assured knowing that your dental health providers will be able to help you if they appear.
