Allright, I don't know what's going on. For the past two weeks I've been experiencing severe tooth/jaw pain in my left jaw area. Back in October I had a cleaning and some xrays done, which showed nothing but an old amalgamate filling. The dentist replaced it with a composite filling, and all was fine. I had been experiencing some minor sensitivity on both sides to cold (sometimes) and sweets, but that's "normal", I guess.
