Q. I recently(3 months ago) had a crown done. When my dentist put the final crown on, the back side could not be flossed. After 30 minutes of trying he ended up drilling between the two teeth to make a gap. I now have what feels like a huge gap between my two back teeth. I can’t eat on that side because the teeth now are to sensitive. They weren’t that way with the temp crown. I went back to him and he told me I have pulpitis. What I want to know is this common to drill between two teeth?
