The visual display [presence] of the interdental papillae, that is, pink tissues, is notably preferred to the absence of the interdental papillae when replaced by either a "black triangle" or long contact area in the commonly known low smile line. This emphasizes the need to assess the Interdental Smile Line (ie, visual display of interdental papillae during smiling) in all patients and the importance to preserve and/or re-establishment of the interdental papillae, that is, pink tissues, even in patients with a low smile line.
