Interesting, if true.

I think I'm teething.

Not my wisdom teeth; genetically speaking, I'm not due for that for another twenty years (my mom didn't get hers done until I was in high school).

At first I thought it was a canker sore, or I bit it or something. I couldn't understand why it would be sore on the red mark.
And then I got to playing with some mirrors, to get a good look at it, and then I did some googling of infants teething, and, lo and behold, they look more similar than I would like. And I'm not pleased.

Damn, no wonder those tots cry so much.

To top it all off, a pacifier won't help things.

Insert your own sucking/oral fixation joke here.

After talking to Steve,he suggested that it could be an adult-onset tongue thrust, which is caused by years of improper swallowing.

If that's the case, you can insert your own "bad homo, doesn't know how to swallow" joke.
