I have a toothache. It's not that bad, just a mild ache when I bite or when I jump or walk to hard. This tooth is always sensitive to sweets and I've had mild pain in it before. Around 7 or 8 years ago, I knew for sure I had a cavity in it, but the dentist came to the decision that it just is because I clinch my teeth when stressed and it takes most of the pressure from that. And so I have been aware of the clinching and soreness since and it does become sore when I'm stressed and clinching. Last year, I again decided I had a cavity because there was pain there (not mild soreness), but it turned out I had my first and only sinus infection. The pain went away when the sinus infection cleared up. It's been sore again for the past week. Quite a lot has happened lately. I had a miscarriage, got a cold, and started having multiple sclerosis symptoms again that I had not had since before I was pregnant with DS. I have noticed that I am clinching my jaw again and haven't gotten fully over the cold yet. But I'm worried about this tooth still. The surface isn't as shiney feeling as the others. Could be I'm just paranoid. Should I go to the doctor to see if I have a sinus infection? Or to the dentist to see if the tooth is okay? Or just do some yoga to try to relax? I've read through a lot of archives and chewed on a clove to try to make it a little less sore. Was that ever strong. I still feel something when I step to hard.
