Take a photo of someone and see what kind of smile they give you: smirk, closed lips, partial smile or wide grin.  A smile says a lot about someone and how they feel about their teeth usually has a lot to do with their confidence level.  If someone likes how their teeth look, a large toothy smile is usually what you will get.  In contrast, someone who doesn’t like their teeth often has a closed or partial lip smirk.
