Cracking Jaw?

Hi - I have this too - it has periods of almost disappearing and others of being really annoying - sometimes its hard to get my jaw back into position. I asked the dentist about it on monday and she said if it causes pain then they investigate but if not then they don't. She said that eating lots of tough food aggravates it and also sleeping at a funny angle on your face, pushing your jaw out does as well - so perhaps try sleeping differently? Let me know if you find a solution!
