Canals not filled or treated.
If the canals were not properly filled during treatment , then bacteria can infiltrate the space. Part of the root canal treatment is shaping and restoring the core. If something goes awry in this process, bacteria can get into the root canal space and cause infection.
However, if you have a pain in the back of your mouth, unusually sensitive tooth, toothache or noticed a similar change in your dental health we advise visiting your local dentist. A dental abscess is a long term infection at the tip of the root that often goes unnoticed. The infection produces puss that builds up pressure until it finds a place to drain out.
In an upper tooth the root tips are so close to the sinus that the puss can drain into the sinus. The roots of the upper teeth are actually quite close to the sinus membrane, which is very thin and delicate.
During the process of a root canal , specialized tools are used to scrape away infected tooth pulp.
