My teeth are driving me insane!

I think last week I clenched my teeth in my sleep for a couple of nights. Painful jaw, sore teeth and lots of pain... it seemed to ease and then the last few days the pain in about 3 or 4 of my teeth has gone crazy... MEGA sensitive... breathing hurts and don't even ask me to eat some thing hard or cold cause I'll scream.

Anyone else experienced this?

I will have to book an appointment with a dentist after payday but I don't think I will survive. Never had anything like this before.
