Guys: Is it unattractive when a girl doesn't have a pretty smile? (underbite, over bite etc)

Do you guys instantly not find a girl attractive when her smile isn't very pretty? In other words she has an underbite, or not straight teeth etc.

I have an underbite but no lisp and my smile is pretty normal but you can tell i have an underbite but its not severe in my opinion. You just know that i have an underbite if i talk or smile.
