Do you think it is possible to have stress manifest itself in jaw pain?

I've been clenching my teeth for years (all day and night) and my jaw always aches, but it is a familiar ache.

All of a sudden though, behind my wisdom tooth in the back, it is very sore. Like it used to feel when I "teethed" in my last wisdom tooth. (other side)

Grrrr. I don't need the threat of going to a dentist on top of everything else. I'm hoping it is just stress.
