Hello,
in November 2015 I developed caries on the upper left first premolar, at the edge of that tooth (right next to the second premolar). My dentist drilled quite deeply into the first premolar and then placed a white filling. Since then I have had the feeling that there is a large “gap” between the first and second premolars; every time I eat (it does not matter whether it is just an apple, bread,...) food remains in that gap. I also have an unpleasant feeling as if I can feel the filling, as if the tooth is “heavier or foreign”... even if I floss the food out, I still feel as though something is between the teeth. At first I thought it would somehow close up, but it has not and the sensation remains very unpleasant. If I run my tongue along the back of the first premolar, the edge is very sharp, as if it were chipped. This is not my first filling (the others are all fine).  If I floss on the left side between the first premolar (with the filling) and the second premolar, the floss passes through very easily... whereas on the other side between the first and second premolars it barely passes through, and the same is true between my other teeth.
Before the caries developed on tooth 4 and the subsequent white filling, everything was fine. Food never collected there in a way that bothered me or that I could feel, and the edge was not sharp... just a normal tooth :)
I would like to know whether the filling may have been made poorly or “incorrectly”? Or did the dentist grind away too much of the first premolar?  I am also considering having another dentist remove this filling and make a new one.
Thank you very much for your answer.
