So my dentist removed the filling and placed a
crown. The
crown has a short
margin and exposed root on the outside, because of previous gum surgery. The crown took a week to settle down, then I felt fine and could chew and eat anything. After a couple of months, I felt sharp momentary sensitivity to sour and cold and also some momentry pain when chewing dense or crunchy foods. Went back to dentist, he did the biting stick test, again I could not reproduce the pain.
