Why is one of my cheeks larger than the other? Can I fix it? (Photo)

I am 16 years old and one of my cheeks are larger than the other.I do not know if this is apart of growing up and losing baby fat and one is just quicker than the other or something else.I did have braces around 11 and had them removed at 13 and maybe my teeth might have affected my face growth in some way.I would really like to know if I can fix it in any way or slim down the other or it might be a medical problem.
