Related?: The maxillary sinuses are only separated from the roots of the upper molars by 2 layers of cells. If sinuses become inflamed/infected, the swelling pushes on the nerves of the teeth, causing the teeth to hurt. If you have an abscessed upper molar, the spreading infection can irritate the sinuses. So see both your Dentist or an Endodontists, and your Physician or an ENT.
