The interdental papilla, also known as the gingival papilla, is the part of the gingiva that exists coronal to the free gingival margin on the buccal and lingual surfaces of the teeth.

A missing papilla is often visible as a small triangular gap between adjacent teeth.

The intradental papillae become red and inflamed in the early stages of scurvy.
