How can an endodontist trace recurring drainage after retreatment?
If a small gum boil or recurring bad taste appears near a retreated tooth, how does an endodontist work out where the drainage is coming from? I’m interested in how the opening’s location and whether it keeps returning fit with findings from the exam and imaging, and whether tracing the drainage tract can help distinguish a persistent endodontic source from a crack or another nearby source.
What changes would make it sensible to contact the endodontist promptly rather than wait for a scheduled follow-up? I wouldn’t want to infer the cause from appearance alone.

The opening’s position on the gum can be misleading. If the tract is accessible, an endodontist may gently place a radiopaque gutta-percha point into it and take a radiograph to see where it leads. That can help identify a likely source tooth, but it’s one clue to interpret alongside the exam and imaging, not a diagnosis from the surface location alone.
Increasing pain or swelling, more drainage, fever, or facial swelling are reasons to contact the endodontist promptly rather than wait for a routine follow-up. Trouble swallowing or breathing calls for urgent medical care. If the drainage is localized and there’s no worsening or fever, the endodontist can advise on appropriate follow-up based on the exam and your situation.
