What Are Black Triangles Between Your Teeth?

22 February 2024

Have you looked in the mirror recently, and noticed small black triangles in between your teeth when you smile? These gaps can be both a cosmetic concern and an indicator of oral health issues. 

Black triangles are triangle-shaped gaps that form between your teeth when your gum tissue doesn’t fill the space. Approximately 67% of people over 20 years old have these gaps. They have several different causes:

  • Gum Recession: Healthy gum tissue normally hugs your teeth, but age, smoking, and gum disease can cause gums to recede. Exposed roots become vulnerable to bacteria and cavities.
  • Bone Loss: Conditions like gum disease and osteoporosis can lead to bone loss near the base of a tooth, resulting in gum recession and black triangles.
  • Dental Hygiene Habits: Aggressive brushing or using oversized dental hygiene cleaners can damage gums and create gaps.
  • Tooth Shape: Some people have triangular-shaped teeth, making them more prone to these gaps.
  • Thin Gum Tissue: Thin gum tissue is less resilient, especially after procedures like crowns, dental implants, or periodontal surgery.

So, what can you do about black triangles?

Have a chat with your dentist or orthodontist. If you notice gaps forming between your teeth, discuss these concerns. Treatment options will generally include a combination of orthodontic treatment like braces or clear aligners such as Invisalign which can close gaps by adjusting tooth positions. 

Cosmetic procedures such as dental bonding or veneers can help to mask black triangles. In some cases, gum contouring, or reshaping gum tissue can also reduce gaps. You should aim to maintain healthy gums to prevent further recession. This includes being gentle when you brush and floss your teeth, as well as visiting your dentist regularly to monitor progress and address any concerns.

Remember, addressing black triangles isn’t just about aesthetics—it’s essential for your overall oral health. So, whether you seek treatment for confidence or health reasons, explore your options and embrace your smile journey!
