Some years ago I developed what I thought was a mouth ulcer on the gums on the inside of my lower jaw - except it felt hard. As days went by, so this progressed until I could feel something sharp with my tongue and, inspecting it using a torch and mirror, it appeared white. Eventually a small splinter of bone found its way to the surface. Within days, exactly the same thing happened on the other side. I kept both pieces of bone to show the dentist, who was intrigued because he had never seen anything like it.
I think the same thing is happening again. Has anyone else suffered this freakish condition?
