Uneven chin and jowl - advice? (photos)

I have noticed in recent years that the right side of my face (left in photo) has a line that extends from the chin to beside my mouth. It is especially noticeable in photos. I believe it is because I have TMJ disorder and my jaw is uneven. I am not entirely sure what to call the line I am seeing and therefore it has been hard to find recommendations online for treatment. I also attached a photo of my mouth open to show how my chin is uneven. I appreciate any advice I can get.
