slight ow, general worry

On my upper left side where my wisdom tooth was until 3 weeks ago, if you run your finger back along the gumline on the cheek side, above the teeth, there's something really sharp at the far back. Like, sharp like metal or bone sticking out of my gum. There's sort of a generalized ache there, too, but that may be psychosomatic due to the trauma of having practically pricked my finger on my GUMS.

So, I guess I call the oral surgeon in the morning and get it looked at, right? Anybody know anything about this? Dr. Google is giving me no love; it's not in the standard lists of wisdom tooth complications.
