Okay February 18th of this year had molar extracted on the top. I felt something sharp on my gum where tooth was taken out. Told dentist. He exrayed it and said the tooth was totally removed. He felt of my gum and said there was a sharp piece of bone in it, and it would wear away in time.
It is still there and very sore. Feels like it is irritating my sinuses. So where could this sharp piece of bone come from?
