Why do my teeth hurt when i am congested? went to the dentist recently teeth are fine

Sinus: Sinus pressure can press downward on the roots of the top back teeth, and this can throw the bite off and make your mouth hurt until the sinus problem clears up.

Maxillary sinuses: Sit just above the roots of your upper teeth and signals from one can be misinterpreted by the body as from the other. So symptom relief for your sinuses (antihistamine, decongestant, nasal saline or lavage, nasal steroid or chromolyn) can improve symptoms and reduce pain.

Sinusitis: Inflammation of the sinuses can cause pain on your maxillary teeth since the nerves innervating those teeth run along the floor of the sinus.
