I have been having pain in the gum below the very last tooth on the left side of my face (it is on the tongue side). I had a dentist look at it today but he did not seeing anything.
On further examination on my own I worked my finger lower down the gum line (kind of hard because the tongue gets in the way) and felt a tiny pin-size hard protrusion. Almost like you would feel when a nail get pounded too far into a board and barely comes out the other side.
This appears to be at least a part of the cause of the pain, although the gum in that whole area is sore, especially when eating.
Any thoughts on what this could be? I wish I had noticed it before my dentist appointment so I could have shown him.
