Whitening, Failing-Bonding Removal & Black-Triangle Closure
Teeth whitening, failing-bonding removal, and black-triangle closure combined in one cosmetic case — before and after.
Bleaching & Excess Failing Bonding Removal & Black Triangle Space Closure
This case combines three cosmetic steps — professional whitening, removal of failing bonding, and black triangle space closure in Maspeth, Queens — to refresh and rebalance the smile. Worn or discolored composite is replaced, while small dark gaps near the gumline are closed with carefully contoured bonding for a brighter, more even result.
Black triangles are the small dark spaces that can appear between teeth near the gumline, often after gum changes or orthodontic treatment. When older bonding has discolored or begun to fail, replacing it at the same time as whitening allows the new restorations to be matched to the brighter shade. The result is a smile that looks cleaner, more uniform, and more youthful while preserving healthy tooth structure.

Final shaping, finishing and polish
Sequencing whitening before bonding allows the new restorations to be matched to the final, brighter tooth shade.
Q1. What causes black triangles between teeth?
They are usually caused by gum recession or changes in tooth shape and position, which leave a small open space near the gumline.
Q2. Should I whiten before or after bonding?
Whitening is generally done first, so new bonding can be matched to the final, brighter shade. Bonding itself does not change color with whitening.
Q3. Can old bonding be replaced?
Yes. Bonding that has discolored, chipped, or worn can be removed and replaced to refresh the smile.
