The jaw line seems to be aligned, but there seems to be more "fat" on the left side than my right? (photo)

It is almost like the left is "swollen", because other features of my face (i.e. mouth and eyes) seems to be pushed away due to the extra "fat". My left ear also feels itchy. My initial hypothesis was that excess chewing on left side made it muscular, but I don't think this is the case, because chewing on the right for 3 years made no difference. Could this have been caused by something, like dental work (from taking out 4 adult teeth all at once!), because I never had an issue like this before.
