Black triangles, the small gaps near the gum line between teeth, are often caused by gum recession, bone loss, periodontal disease, or orthodontic treatments like braces. While not harmful on their own, they can trap food and cause oral problems.
Causes：
- Gum Recession：Common as we age, it’s the loss of gum tissue around teeth.
- Bone Loss：Reduces tooth support, resulting in gaps.
- Periodontal Disease：Damages gums and bone.
- Orthodontics：Braces can change gum lines, creating black triangles.
Prevention：
- Good Oral Hygiene：Floss daily to prevent gum disease.
- Regular Dental Visits：Early detection helps avoid issues.
- Avoid Tobacco：Smoking speeds up gum recession.
Treatment Options：
- Orthodontic Correction：Braces or Invisalign can close gaps.
- Gum Grafting：Restores gum tissue to fill gaps.
- Veneers or Bonding：Cosmetic solutions to cover gaps.
- Hyaluronic Acid：May improve appearance.
Conclusion：Black triangles can affect your smile, but with proper care and treatment, you can fix your smile and keep good oral health. Talk to your dentist to find the best solution for you.
