La sinusitis Is an inflammatory process manifested by headache especially in the morning, localized on the root of the nose and on the eye sockets, but also with nasal secretions: sometimes it can be caused by dental problems!
Indeed the roots of our upper molars and premolars end near the maxillary sinus, an air-filled cavity located at the level of the cheekbones.
If one of these molars or premolars becomes infected, it is not uncommon that the infection spreads to the sinus itself, causing secondary sinusitis (o odontogenic sinusitis).
How to tell if Sinusitis is thus caused by a dental infection (which - apart from the typical manifestations of sinusitis - can be asymptomatic and therefore even more difficult to diagnose)?
Patients with Odontogenic sinusitis does not improve with antibiotic use and with the therapies that typically work with sinusitis; therefore, in such cases, dentists are called in to evaluate patients with sinusitis symptoms who have not found benefit, other than temporary, from antibiotic therapies.
