1 weeks post. Will my black triangles fill in? (photo)

Gums take 3-4 weeks to fully heal after any treatment. I would wait at least that long to see what the final result will be. The black triangles are minimal. There are procedures that can be done like fillers, but that wears off over time and needs to be redone.

Hi:The gums appear to be inflamed.  I would wait another 2-4 weeks to see where the gums end up prior to deciding as the next step.Best,Dr. Maddahi

These will most likely not resolve. Only option is to redo and recontour the crowns. Be sure and check them before cementation to be sure you are happy with them.  I believe you could get a better cosmetic result.

 Hello The black triangles won’t close by themself so; the only option is to repeat the crown or adapt to the triangles that don’t look bad.
