A few yrs ago I had my back molar removed. I had a lot of pain down to my jaw and was very sensitive. They didn't know what was causing it. due to that, I only chewed on the opposite side for years. Now 6 years later I noticed my face is asymmetrical. My massester on the side I didn't chew on seems Nonexistent. the side I did chew on looks much larger. Could this be massester atrophy due to how I was chewing all these years or something more serious? Or related to never getting a fake molar?
