What this video covers:

The effects of contaminates leaking from a tooth's root canal system.

We've selected just a small segment of this video for viewing and are using it to illustrate how contaminates harbored inside a tooth (like those that exist after coronal leakage has occurred) can serve as a persistent source of irritation to the tissues that surround the tooth's roots.

As mentioned in the video, most of the time this irritation may exist as low-grade, mostly asymptomatic, chronic inflammation. But at times it may flare-up in the form of an acute tooth abscess (pain, swelling).

Either way, due to the fact that the coronal leakage has occurred the tooth's previous root canal treatment must now be considered a failure. Extraction or endodontic retreatment are the only two clinical choices.
