There is a hole in one of my upper teeth on the right side. Up until recently it hadn't caused me any trouble but a few days ago it started up in the middle of the night and worsened over the next day or so. I needed to take some Panadol to ease the discomfort. At the same time, the gaping hole where a tooth used to be on the upper left side of my mouth also become inflamed. I was having difficulty eating.
I suspect I walked too far on the day preceding my oral woes but I can't remember the exact chronology. Nowadays, when I push my body too far, I seem to suffer a general collapse. Today, after a couple of days of not walking, my teeth troubles have largely subsided. I have to accept that my body is not what it used to be and I have to "exercise" more caution.
