What is the interdental papilla?

1. Projection of the tongue

2. Projection of gingiva between the teeth

3. A type of dental filling

4. Membrane adjacent to the gums

The correct answer is: Projection of gingiva between the teeth

The interdental papilla is a small, triangular piece of soft tissue that fills the space between two adjacent teeth. It is an important part of the gingival tissue and plays a critical role in oral health by maintaining the barrier against bacteria and food particles that can lead to periodontal disease. The interdental papilla helps to protect the underlying structures of the teeth and gums, promoting both aesthetics and function. Its presence is key in providing a proper interproximal contact point between teeth, contributing to the overall stability of the dental arch. In contrast, the other options refer to different anatomical structures or dental components—such as the projection of the tongue, which is not related to the gingiva; a type of dental filling, which involves restorative material used to treat cavities; and membranes adjacent to the gums, which could refer to various types of oral mucosa but do not specifically define the interdental papilla.
