Lock Jaw

Yesterday I locked my jaw open when I yawned in speech class. Felt a snap when I tried to put it back in place, and its feeling slightly tender up to now. I can only open my mouth so much when I brush my teeth coz it feels like it could lock again and it makes clicking sounds when I chew. If this gets any worse, I'm seeing my dentist. Otherwise, my next boyfriend's cock can't be thicker than a Sharpie.
