Unsightly spaces between the teeth, known as black triangles, are often caused by botched cosmetic dental procedures involving porcelain veneers, gum recession, bone loss and gingivitis. The black triangles can expose the gumline to bacteria and plaque that will eventually lead to permanent decay and possible tooth loss. There are no simple, at-home solutions for fixing black triangles between teeth, and cosmetic dental surgery is often required to repair the receding gums and replace lost bone.
Gently clean the gumline to help reduce inflammation due to gum disease. Occasionally, black triangles will result after gum disease sets in and irritates the gums, causing unsightly gaps between the teeth.
Consult with a cosmetic dentist to determine how severe the damage is. During your consultation, the dentist will recommend different surgical procedures based on the severity of your gum recession and black triangles. In the event that the black triangles were caused by an improperly performed prior dental procedure, a new cosmetic dentist may be able to repair the problem.
Repair improperly performed crown or porcelain veneers. This could mean having the old crowns or veneers removed and completely replaced if the original procedure was performed improperly.
Undergo corrective surgery, like papilla regeneration, which regrafts the gumline and repairs the soft tissue between the teeth. This surgery will not only fix black triangles, but can help cut root exposure to permanent damage.
Prevent future gum damage once the black triangles have been repaired, by properly caring for your teeth. Regular brushing and flossing can help reduce the risk of gum disease that may result in the gumline receding again, causing a recurrence of black triangles.
