An essential part of anyone’s smile is not just the teeth but also the gums that surround the teeth. There should be a maximum of 2mm of gum showing when smiling widely for the look to not appear too gummy. These people have their lips, gums, and teeth relationships on different levels. In order to create the ideal gum line gum sometimes needs to be added (cosmetic tissue grafting) of removing (gum lifts) to give the ideal result to your smile.
