Can I do anything with my chin protruding when I smile? (Photo)

Anytime i smile my chin is sticking out or protruding and it makes my smile really ugly or just not appealing to look at and i always hated it, im also worried that if i lose fat on m face then it will be visible even when im not smiling. I wanna know if theres anything i can do about it to make it look normal and round not sticking out when smiling or other times.
