Black triangles are the small dark gaps that can appear between teeth near the gumline. They are common and there are several ways to close them.
Quick answer
Black triangles are dark spaces between teeth at the gumline, caused by gum recession, bone loss, tooth shape or after orthodontics. They can be closed with composite bonding, veneers, or by moving the teeth with aligners. Treating any gum disease first is important. Bonding is the quickest, most common fix.
Why they form
- Gum recession or bone loss.
- Triangular tooth shape.
- After braces or aligners as teeth straighten.
How to close them
- Composite bonding - adds material to fill the space, quick and affordable.
- Veneers - reshape the teeth for a lasting result.
- Aligners - move teeth closer in suitable cases.
