Can my nasal sinuses cause tooth pain?

Yes: The roots of the bicuspid and molar teeth sit just below the lower portion of the maxillary sinus, and inflammation in the sinuses can produce dental pain. But often, if there is apical root disease in those teeth this can result in secondary sinus infection. See a good ENT doctor and they will work this out.

Yes: The upper molars have roots that develop in close proximity to the maxillary sinus. Infection and congestion the maxillary sinus may cause the upper molars to become extremely sensitive to cold and biting.

Yes?: I assume that you meant the nasal sinuses are the maxillary sinuses. The roots of the back upper teeth can protrude or are in close proximity to the maxillary sinuses. If the sinuses are flaring up, this can cause your teeth to be sensitive.

Sinus Tooth Pain: Because in many instances the roots of the maxillary molars and bicuspids sit near or into the nasal sinuses, when there is a sinus infection, the teeth can become very sensitive mimicking tooth nerve pain. It is very important to inform your dentist if you just got over a cold or flu. Many times this is when this condition appears. If a dentist rules out a tooth nerve problem, see your md.

Yes, and vice versa: Maxillary sinusitis can cause upper posterior tooth pain. Infected upper posterior teeth can cause sinus infection and pain. See your dentist to sort things out.

If top back teeth, yes. If other teeth, no. Sit down. lean over and put your head between your knees. If pain gets worse, probable sinus involvement. If pain level remains the same, probably a dental problem. May be both. See both your Dentist and Physician for screening exams.
