Strange (awful) odor after root canal
I've been experiencing a strange odor since about a week after a root canal I had a month or so ago. I'm going in for the crown soon. The odor is akin to rotting meat and is triggered by some smells, but more substantially by a few specific ones. Diesel exhaust, for instance, is probably the worst, and my body odor is noticeably more potent, but only noticeable by me. I have a bit of pain if I bite down on the tooth, but only a tiny bit. Currently the tooth is cemented over awaiting the crown. I've read a few things saying it could be bacteria under my tooth from the root canal and I'm wondering if that's the case. If that is the case, would I have to pay for more dental work and potentially a new crown? That's the worst case scenario, second only I suppose to a brain tumor.
Thanks for reading.
