Naturally, teeth should sit in a way that is both aesthetically pleasing and functionally optimal. Ideally, the edges of the upper front teeth should be parallel to the curve of your lower lip when you smile.
Here's a breakdown of the key elements:
-
Upper Incisal Edge Position: The biting edges of your upper front teeth should gracefully follow the contour of your lower lip line when you smile. This creates a balanced and harmonious appearance.
-
Gum Display: The amount of gum visible when you smile is also important. Too much gum showing can make the upper teeth appear too long.
-
Midline Alignment: The center line between your two upper front teeth (the upper midline) should ideally line up with the middle of your upper lip. Furthermore, this upper midline should align with the lower midline (the center between your lower front teeth).
In summary, naturally sitting teeth exhibit alignment that harmonizes with the lips, appropriate gum display, and proper midline coordination. This contributes to a pleasing and functional smile.
