Cause #8: Dental Infections
Another possible cause of sinus infections are dental problems. The maxillary sinus, which is also the largest of the sinuses, is usually involved due to the fact that it is located very close to the maxillary teeth. Any problem with maxillary teeth allows the infection to spread easily to the maxillary sinus.
According to some estimates, odontogenic sinusitis, the one originating from teeth, is thought to account for up to 40% of all maxillary sinusitis cases. Sinusitis is also common following dental surgery when the Schneiderian membranes are ruptured.
