I’ve had a dodgy tooth for a while now but my dentist assured me there was nothing wrong that a bout of using mouthwash and diligent flossing wouldn’t cure.  So I embarked on a course of oral hygiene and thought things were moving along swimmingly when, the day before yesterday, I made the mistake of masticating a bowl of chilled yogurt using both sides of my mouth and a sudden jolt of pain hit me in the temples.

Since then, life has been lived on the precipice.
