When/why did baring your upper teeth become equated with smiling?Watch
- Study Helper
Are they trying to show off that they went to the orthodentist, had their teeth aligned, and whitened?
Are they trying to growl and smile simultanesouly, baring their canines?
Or are they just incapable of smiling?
My current hypothesis is that it started as a fashion trend after the Bee Gees.
And hmm interesting question, not sure but smiling with teeth open is closer to laughing so maybe it's just a 'bigger' smile?
