Is it normal for you??? I’d say YES!!!
Is it normal for me??? Nope.
NOT everybody shows teeth when they smile & I’ve NEVER heard that showing teeth is a requirement…it’s just natural for me!!! Since it doesn’t seem normal for you, forcing it would give you a FAKE smile which is WORSE than not smiling at all.
Do what feels normal for you!!!
When I smile, I usually don’t show my teeth that much. I don’t have the greatest teeth in the world so it might be some sort of subconscious desire to hide that fact, but I just don’t smile that way. My brother, on the other hand, in every picture I’ve seen of him on Facebook, insists on having this huge grin on his face with all his teeth showing. Somebody’s got to tell him at some point that that smile not only really looks fake but is a bit frightening, lol!
A lot really depends on how big your teeth are. My teeth are small and while I have no problem showing them, it just doesn’t naturally happen when I smile.
