What would be the best way to treat my black triangles? (Photo)

Black triangles can be treated in various ways depending on the cause and severity. It's essential to first determine the underlying reason for these spaces between your teeth. They can result from gum recession, bone loss, or simply the natural shape of your teeth.
Here are a few potential treatments:
Cosmetic Bonding: For mild cases, composite bonding can fill in the spaces between teeth, improving aesthetics.
1. Orthodontics: Braces or clear aligners can help if the black triangles are due to misalignment. Aligning the teeth can reduce or eliminate these spaces.
2. Gum Recontouring: In cases where gum recession is the cause, gum recontouring procedures can be performed to reshape the gumline, reducing the gaps.
3. Dental Veneers or Crowns: These restorative options can be used to cover and fill in spaces between teeth for a more uniform appearance.
Periodontal Treatment: If the cause is gum disease or bone loss, addressing the underlying periodontal issues may help prevent further recession and reduce the size of the black triangles.
It's crucial to consult with a dental professional like myself to assess your specific situation and determine the most suitable treatment option for you. The best approach will depend on the cause, your oral health, and your aesthetic goals.

Hello. Although there are alternative ways of treatment for closing those gaps, the most reasonable method is mostly prosthetic which consists of Emax laminate veneers or crowns. Composite fillings (a.k.a. bonding) are easily discolorated long term and have less strength.
