These pictures are ~5 years apart. I am trying to figure out if the changes in my face are natural aging, one round of cheek fillers that possibly migrated (I don't know this for a fact but speculating), weight gain, TMJ related (I have arthritis in my jaw, grind my teeth, and wear a mouth guard at night) or something else. What would help? Jaw surgery? A facelift? I'm 43.
