Not sure if this is a dental issue but....

My jaw is uneven. The left side has more muscle then the right. I’m not sure if it’s just genetics or because I chew food more on my left side of the mouth. Please help.

 

Because of this my lips are slightly uneven and there is more of an indent coming off the nose of my right cheek.

 

Very few people have perfectly symmetrical faces. If you take a straight on photo of your face then split it down the middle and then double up each side, you'll end up with different faces. Movie stars and TV presenters are often selected for their facial symmetry, the rest of us are a bit different (mutants!). That's life.

 

I mean, you can build muscle in other parts of your body. Is there really no way to even out facial muscles?

 

No. Facial muscles can't be worked separately. They work together.
