Gingival Embrasures: What Are The Black Triangles Between Your Teeth?

Written by Danica Lacson on September 27, 2018

What are the black triangles between the teeth?

Also known as gingival embrasures, the black triangles develop between the teeth, leaving them looking old and dark because of the contrast of the teeth, pink gums, and the dark space.

Why do black triangles form between the teeth?

  • Teeth shape. When the teeth are triangular, there is a tendency of a large teeth gap to develop as the teeth connect only at the chewing surface and not near the gum line.
  • Gum recession occurs when the margin of the gum tissue surrounding the teeth wears away due to periodontal diseases, genetics, overbrushing, inadequate dental care, hormonal changes, tobacco use, teeth grinding or clenching, a misaligned bite, or tongue or lip piercing.

How can the black triangles between teeth be removed?

Gingival embrasures are unpleasing and age the smile. They are also more susceptible to food debris accumulation and plaque buildup.

Veneers or bonds can change the shape of your teeth and eliminate dark triangles. Teeth reshaping or interproximal reduction can also be made to fill the sides of rounded or triangular teeth to close them together.

If gum recession causes the black triangles, it is necessary that the cause of the gum recession must be addressed. Mild cases of recession can be treated through a deep cleaning where plaque and tartar on teeth and root surfaces are removed and smoothed to prevent bacteria from attacking them.

Your dentist may also recommend antibiotics to rid you of the remaining bacteria. If the gum recession has reached a severe level such that there is excessive bone loss and pockets have become too deep, a gum surgery may be needed.

Gum surgeries can be open flap scaling and root planing, regeneration, and soft tissue graft. Consult us at Hawaii Family Dental for the best procedure to use based on your condition and needs.

How can I prevent black triangles from forming?

We also advise the practice of proper oral hygiene like brushing, flossing, and visiting us at least twice a year. If you have misaligned bite, our orthodontist can help correct the problem.

Be wary of your lifestyle. If you are smoking, quit the habit as early as possible. A well-balanced and healthy diet is also necessary for maintaining oral health. You can eat foods like cheese, apple, cashew, yogurt, and the like for your oral health as these foods provide nutrients to your teeth.
