That's all you need on top of everything else, but it sounds like you need to see the Dentist. I have a twisted bite from an accident when I was a child, fell of my Horse and dislocated my jaw, every now and then I have to have a brace to pull it back, not as much now as I did when I was a child. I was told once you have a dislocation the joint is weak and can come back from time to time.
Hope you feel better soon and dont let it get to bad as you need to eat.
