How long does it take a sinus communication to heal?
Sinus communication: A sinus communication occurs when a very small hole is made in your sinus lining. Sinus communications are the most commonly experienced side effect of a root canal.

A hissing noise from air leakage through the maxillary sinus and nose indicates a positive test.
What causes oroantral communication?
An oroantral communication (OAC) is an unnatural space that forms between the maxillary sinus and oral cavity following extraction of antral teeth, infection, or several different complications. If left untreated, an OAC can develop into an oroantral fistula (OAF) or chronic sinus disease.
How is OAC diagnosed?
Depending on the size of the potential communication and in what context, a small radiograph inside the mouth may be sufficient (a periapical) to assess for any break in the bone of the sinus floor which may indicate an OAC. – Panoramic radiographs can also be used to confirm the presence of an OAC.
