Do I have unilateral TMJ disorder? Is this normal?

The right side of my jaw muscles are mildly atrophied/ smaller than my left side.
The right jaw joint cracks (non painful) when I open it widely or when I bite into an apple and I have difficulty moving my jaw side to side ( it only gets stuck when move it towards the right side ( the smaller side) .

I noticed that I predominantly chew on my left side.. and it feels slightly uncomfortable when I chew on my right side.

Could my “right tmj” progressively wear out and become painful in the future if I don’t seek treatment now or is this considered normal?
