What is that bad smell during a root canal?

Bad odor: If you smelled a bad odor coming from your tooth during treatment it is probably infected, and that is why it had a bad smell.

Bad Smell: That is the decayed or necrotic tissue caused by bacteria inside the tooth.

Abscess: If your tooth was necrotic when the treatment was started, it is very likely that the bad smell is coming from the pus that was present inside your tooth.
