Even though I had 4 teeth extracted and braces when I was in high school, my mouth still feels like it's protruding...
And it's always hard to close my mouth. I have to be conscious
of it and close it . If I'm not conscious of it, it opens up and when I close my mouth, it looks like a walnut.
I wonder if it's because I have a chinless jaw, or if it's just a weak muscle or a protruding mouth.
