Can chronic sinusitis cause severe upper molar pain?

Yes: The "upper teeth" or mandibular teeth.. Not just molars are just under the maxillary sinus cavity. An infection of the sinuses can cause tooth pain. In fact i ask my patients with sinusitis if they have tooth pain as a symptom. However, severe tooth pain could also be a dental infection... Best to get both checked out.

Yes: The roots of the upper molars can go up into the sinuses. When the lining of the sinus is inflamed the roots can also be inflamed causing pain.

Yes: The upper molars often terminate in the sinus, and with chronic sinus infections this will put pressure on these molars causing pain.

Very common: also called a dental sinus. Very common when the roots of the upper molar teeth are in close proximity with the sinus area. Removing the dental and gum infection is the only successful treatment for a dental sinus. See your dentist for consultation and treatment.

Yup: See it all the time. Patient is confident there is a dental problem when in fact there is none. Pain is referred from the floor of the sinus to the teeth.

Yes: The last three or four teeth in the upper jaw have roots that are in close relationship to the floor of the maxillary sinuses. It is not uncommon for patients with chronic sinusitis to have pain radiate into the maxillary teeth. Likewise, patients with dental problems in the maxillary teeth that lie in close contact with the floor of the sinus can refer pain to the sinuses.

Yes, and vice versa: Yes, and an infected upper molar can cause sinusitis. See a dentist to check the teeth out. If teeth ok, see an ENT doc to help with the sinusitis.
