Right or left?

I'm a right-sided chewer.

right-chewer, right-handed. I'm the average Joe,...

I don't get it.

I chew on both sides, swishing it back and forth. Doesn't everyone? I mean, that's how chewing works.

Wait... I tried it out, and I tend to start out on the right and then move onto the left when the right gets tired, alternating.

I chew on the right because I'm missing a tooth on the left.

Right.

I'm a right-sided chewer, if you know what I mean.
