Black triangle closure
How BioClear helps treat the spaces between the teeth and gumline.
Black triangles are triangular spaces between the teeth near the gums. They can appear after orthodontic treatment, with gum recession, or because of natural tooth shape. These spaces often create an aging effect and can make the smile look less complete. BioClear addresses this by using specialized anatomic forms and heated composite to add shape exactly where it is needed. Rather than shaving down otherwise healthy teeth, the method focuses on rebuilding the contour so the dark space is closed and the smile looks fuller and more balanced.
