Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus , which is in close proximity to the upper teeth .
Dental pain can also occur. A way to distinguish between toothache and sinusitis is that sinusitis-related pain is usually worsened by tilting the head forward or performing the Valsalva maneuver. [21] Chronic sinusitis presents with more subtle symptoms of nasal obstruction, with less fever and pain complaints.
Less commonly, non-dental conditions can cause toothache, such as maxillary sinusitis, which can cause pain in the upper back teeth, or angina pectoris, which can cause pain in the lower teeth. Correct diagnosis can sometimes be challenging. Proper oral hygiene helps to prevent toothache by preventing dental disease.
Causes of tooth pain If your teeth hurt, it could be a dental problem, a general health problem completely unrelated to your mouth, or something else. Before you start to treat your tooth pain, it ...
Infections associated with teeth may be responsible for approximately 20% of cases of maxillary sinusitis. [7] The cause of this situation is usually a periapical or periodontal infection of a maxillary posterior tooth, where the inflammatory exudate has eroded through the bone superiorly to drain into the maxillary sinus .
Pain can also be referred to the upper teeth and be mistaken for toothache. [4] Another symptom is the movement of fluid from the mouth through the communication and into the maxillary sinus, as the maxillary sinus is connected to the nose and therefore fluid can come out of the nostrils when drinking.

ATN pain can be described as heavy, aching, stabbing, and burning. Some patients have a constant migraine-like headache. Others may experience intense pain in one or in all three trigeminal nerve branches, affecting teeth, ears, sinuses, cheeks, forehead, upper and lower jaws, behind the eyes, and scalp.
Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [1] Furthermore, the drainage orifice lies near the roof of the sinus, and so the maxillary sinus does not drain well, and infection develops more easily.
