The interdental papilla is a small cartilaginous or fibrous projection in the gum between the teeth that is used to hold food between them. It helps prevent bacteria and food from accumulating between teeth and maintain healthy gums.
There are upper and lower interdental papillae, which can have different sizes and shapes. Interdental papillae can be of different shapes, colors and sizes. Size and shape depend on individual characteristics. Usually the color of the interarticular papillae does not change and they should be the same as the gums. This does not signal pathology. Interdental papillae create chewing efficiency that can be reduced by improperly aligned teeth. Sometimes dentists use a pin between the teeth instead of a pin
