Can an inflamed tooth cause a sinus infection?

Inflammation of the teeth may lead to sinusitis, especially the upper teeth, and there are clinical reports related to odontogenic sinusitis.

Since the oral cavity and nasal cavity are only separated by the maxillary bone, if the wall of the maxillary sinus is too thin, when the bacterial virulence increases or the body’s resistance decreases, the local inflammation can spread from the oral cavity to the maxillary sinus, thus inducing sinusitis, and the serious condition can also appear systemic symptoms.
