I either have the beginnings of a tooth going bad or I managed to ding the ligaments in my jaw. I think/hope it's the latter; not only is the nearest tooth to the ache a crown I've had for about eight years, there wasn't even a twinge when I ate dinner (beef and veggie stir-fry). The ache is fading so I hope I'm right; I *really* cannot afford any major dental work right now.
