Back from the dentist, the left side of my jaw numb, I do what I had been advised: I eat an ice-cream, pop a painkiller and swallow a mouthful of water to chase the painkiller down.
Ten minutes later, I drink water again, and as the water moves about in my mouth, I suddenly feel a cuboidal something in my mouth. WTF. Did my teeth come loose?
Turned out, it was the painkiller, with my mouth numb, I didn’t do a good job of swallowing, and then didn’t notice while the pill nested itself in the far back of my mouth.
