Bruxism is the unintentional grinding and/or clenching of the teeth. It is often associated with activities related to stress such as concentration, exercise, computer work, driving, anxiety, lack of sleep.
So says this bright pink flyer they gave me at the dental clinic today. Apparently this is the cause of my headaches and ears ringing and pain while yawning. Heh. The dentist advised that I should avoid the "unintentional grinding and clenching". Unintentional being the key word there. I don't know if he understood.
You know how they say "DO NOT think of an elephant" and... Yeah. Ever since I came back from the dentist all I've been doing is clenching and grinding. My teeth, you sickos.
