What causes the appearance of black triangles between teeth? And how can porcelain veneers conceal them?

Five Causes of Black Triangles

  1. Tooth Shape: Some people have teeth that are shaped at a slant, and it causes them to fit tightly at the base but have spaces between them at the top.
  2. Gum Recession: Gum recession can be caused by several factors, including age, gum disease, and aggressively brushing teeth. With less gum tissue to cover the tooth structure, black triangles can form.
  3. Bone Loss: Bone loss is often caused by advanced gum disease, although there some medical conditions or other factors that might cause it.
  4. Deep Cleanings: Severe, untreated gum disease (periodontal disease) causes a build-up of debris on teeth, localized infections, and inflammation. After a deep cleaning, also called scaling and root planing, the inflammation improves and gums get healthier. As the inflammation decreases, gaps between teeth, including black triangles, might become noticeable.
  5. Trauma: Trauma to your gum tissue from excessive brushing; regularly using sharp or blunt objects to pick or floss between your teeth; or aggressive dental work can damage the gum tissue and leave spaces between your teeth.
