Is my chin too large whenever I smile?

I know that I am a male, and I am aware that I am only 18 and still have the developing to continue... I just don't feel comfortable with how large and full my chin looks whenever I show my teeth. I was wondering if there is a surgery to shave it down maybe a centimeter or so.. Or any other thoughts or suggestions are welcome. Except chin implants, I am not too sure about those. I have read very mixed reviews. Thank you, in advance to whomever responds. I know these photos aren't the best.
