I recently got all my teeth done due to a collapsed bite with porcelain crowns. I have been waking up with a cut right in the middle of my upper lip. I'm guessing it's from my 2 front teeth because the cut is right in between both? Also, When the work was all done my back bottom tooth crown was on for a while but then started to come out. I had it re cemented but since then I have been tasting a weird taste in my mouth only in that area. Almost like it wasnt sealed properly? Is that normal?
