It started on Thursday, when I took a nap and woke up with a mild, general tooth pain in a lateral incisor, and had slightly affected my central incisor. I thought I had been grinding my teeth in my sleep, as I often do, so I swished around warm salt water, took a Tylenol, and called it a day.
Friday, it was more prominent but not painful or obstructive. I did notice a numbness in my upper lip, and it was a tad swollen.
