Well, the dentist did say that if we left things a few days then the guilty tooth might announce itself. And lo, so it has done. I went fairly suddenly from having intermittent intense pain throughout one side of my jaw to having classic toothache in one specific place. Oddly my mouth also went from being intensely sensitive to heat to being intensely sensitive to cold at the same time. A very strange thing, the human nervous system.

Of course this doesn’t mean the problem is solved. To start with I have to live with this until Monday morning when I can get the dentist to do something about the offending tooth. In addition I don’t know how serious the problem is. Last time I had a tooth go bad it went from filling replacement to emergency root canal to gold tooth in the space of a week. That gets expensive very fast.
