Black Triangle Closure: see it on your own smile first
Fill the dark triangular gaps between the front teeth.
Black triangles are the small dark gaps that appear between teeth near the gumline when the gum papilla no longer fills the space — commonly after gum recession, periodontal treatment, or orthodontics in adulthood.
The mainstream fix is additive: composite is shaped onto the sides of the teeth to broaden their contact and fill the triangle with tooth rather than shadow. Done well it's genuinely hard to spot; the gum itself isn't 'grown back', which honest dentists will tell you upfront.
What your Smyly™ preview shows
Smyly™ previews your smile with the triangles reduced and with them closed, so you can see how much of the change you actually want before anyone touches a tooth.
You'll see 2 versions side by side: Reduced, Closed .

The honest limits of this preview
Filled with tooth-coloured material. Cannot regrow lost gum tissue. A preview can't see bone, bite, gum health or anything beneath the surface — only a clinical exam can. Treat it as a conversation starter for your dentist, never as a promised result.
Worth asking your dentist
- Why did my papillae recede, and is the underlying gum condition stable?
- Will closing the triangles with composite create areas that trap floss or plaque?
- How do you keep the reshaped teeth from looking bulky at the gumline?
