Is There Any Way to Create the Illusion of a Bigger Mouth on a 17 Year Old? (photo)

I am very self conscious about my mouth and lips. My upper lip has only the middle part sticking out and my bottom lip is full and big. I feel this overall, creates the impression of a small mouth. I am not the only one who has noticed this as my close friends initially pointed it out a few years ago, as they said I have a small mouth and resemble a koala. Would it be possible to create the illusion of a wider mouth? I am not by any means overweight.
