Several of my portraits lately have included toothy smiles (some at the parents' request, some were posthumous portraits from existing photos, etc). I didn't charge extra.
For me the key is not to make the teeth too bright. I found the best "color" for teeth is varying mixtures of burnt umber and white. That way they're not too yellow and not to grey.
The drawing of the teeth has to be perfect (each tooth exactly the right size and shape, etc) or it won't look right. It's as time consuming as doing the eyes, if not more!
Of course, many people feel that a portrait should show a more subtle, timeless expression than what you get from a toothy grin. I guess that's up to each artist and client to decide.
