For a non-vital tooth with an associated fistula, which treatment is appropriate?

In the case of a non-vital tooth exhibiting a fistula, the most appropriate treatment involves performing root canal procedures without necessitating additional interventions specifically for the fistula. This approach addresses the underlying issue, which is often an infection within the pulp of the tooth. The root canal treatment effectively removes the infected pulp tissue and cleans the canal system, thereby alleviating the source of infection that could contribute to the formation of the fistula.

Once the root canal procedure is completed and the tooth is sealed properly, the fistula typically resolves as the source of the infection has been eliminated. It’s important to note that while the fistula may drain pus or fluid, treating the tooth itself is the priority, as this is where the infection originates.

While antibiotic coverage may be useful in managing infection prior to or in conjunction with the treatment, it does not resolve the problem of a non-vital tooth nor does it cure the underlying cause. Surgical intervention may be required in some cases but is not the first line of treatment when a root canal can effectively treat the issue. Peripheral filling procedures do not address the essential problem within the pulp and would not effectively treat a non-vital tooth with a fistula.
