I actually think there's a little more going on than a simple grin cut into his face. Mutilation wouldn't explain the dimming bulbs, the fact that he couldn't feel that he was grinning with his fingertips, the phrase "I never knew my mouth was so wide" or that he's continuing to count past 38 teeth in the smile when humans only have a total of 32 teeth.

A lot of legends suggest worlds and creatures that're visable through mirrors, often considered gateways for ghosts and spirits. Chances are the author was suggesting the man's reflection was no longer his reflection, but rather something that looked similar enough to him that he wouldn't catch it right away; except for the grin on its face.
