Several times this year I've woken up at 2am with HORRIBLE throbbing dental pain (upper left). For someone with a high tolerance for pain, I would put this at something like an 8.5 on a scale of 1-10. Each time my dentist came to the conclusion that since there wasn't anything wrong with my teeth that it had to be from sinus pressure.

I had this happen last night - it actually impacts that entire upper left of my mouth, all teeth, and indeed even touching one of the affected teeth, running my tongue over any of the teeth, or even drawing in a deep breath so that AIR touches that portion of my mouth causes increased pain. If I force myself to lay there and relax my jaw, the pain goes away after about 15 minutes, or at least relents enough that I get back to sleep. One or two of those teeth are typically still sore at breakfast, all signs of pain/discomfort gone by mid-morning and that, is that, until the next time. Thankfully it's only happened two other times this year, and my dentist can't find anything wrong.

I found myself clenching my jaws yesterday, and even had the though before bed that perhaps this might be the cause of it. Then, lo and behold, it happened last night - though not QUITE as bad as in the past. Only a 6-7 rather than an 8, but bad enough.

Has anyone experienced this? If you do sometimes clench your jaws, do you have symptoms like this? I've been though a few different types of stress lately so am wondering if this is actually what is going on. My sinuses seem fine... If this is the problem, it actually makes sense that it is only affecting one side - there are differences between the two.
