can a sinus infection cause tooth pain
How a sinus infection causes a sinus toothache? Sinuses are air filled cavities inside the human skull, lined with a mucous membrane. When someone develops a sinus infection, one of the symptoms may be a throbbing tooth pain which is referred as a sinus toothache. Sinus related toothaches affect the upper back teeth (usually several or all teeth) which are closer to the maxillary sinuses.
