Papilla (Interdental)

The interdental papilla is the small, triangular wedge of gum tissue that occupies the space between neighboring teeth. It helps seal the area against bacteria and food particles, supports the contact point between teeth, and contributes to gum contour and overall smile aesthetics.

Damage or loss of the papilla can result from periodontal disease, bone loss, tooth migration or spacing, and poorly fitting restorations; this can lead to food impaction, sensitivity, and visible black triangles between teeth. Management depends on the cause and may include improved oral hygiene and periodontal therapy, orthodontic or restorative adjustments, or surgical procedures aimed at papilla preservation or reconstruction when feasible.
