About 12-13 years ago I had a crown on a back tooth. The dentist took the top of the tooth off, took a cast, then covered it with a temporary filling for a week or two whilst the crown was being made.
Within 36 hours I had a foul taste in my mouth, and when I rubbed the top of the temporary filling, the tip of my finger smelt exactly like I'd just put it up my bum. No smell from anywhere else in my mouth, just the temporary filling. I went straight back but just got told to clean my teeth more carefully by a smirking dentist. I hadn't been cleaning that tooth any differently for the last 48 hours than I'd been cleaning all my teeth for the previous 50 odd years, so it was hardly surprising that upping my dental hygiene made no difference at all. I went to another dentist for a second opinion, and got a second lecture on cleaning my teeth, so I've just lived with it for over a decade now.
Three months ago the crown fell off, and there on the underside of the crown was that familiar smell of sh!t....
