The
interdental papilla, also known as the
interdental gingiva, is the part of the
gingiva that exists
coronal to the
free gingival margin on the buccal and lingual surfaces of the
teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the anterior teeth and a blunted shape buccolingually for the posterior teeth.
