Why do people not show teeth when smiling?
While the smile is considered the most important feature for selfie shots, more than one in three (36%) do not believe their teeth should feature in their best camera-ready smile and in many cases (33%) say this is because they feel uncomfortable with how their teeth look.
How should your teeth sit when you smile?
FROM THE FRONT: your upper front teeth should fall in front of your lower teeth (toward your lip), and should overlap them by about 2 mm. Upper and lower front teeth should hit lightly. FROM THE TOP (OR BOTTOM): The back teeth should be upright, NOT tipped toward the cheek or tongue.
