Thanks for the tips guys.The pain is actually in the side of my face, head and neck, practically nothing near the teeth, which is why it took me so long to realise what was up ( never said I was bright, did I?).I've never actually had anything wrong with my teeth before and so was feeling a bit stocked and shunned this morning, and no idea how to treat it, but I've just done an afternoons work so it's not that awful.
