Can Tooth Decay & Infection Cause Sinus Congestion?

When the cavities around the nasal passages (also called the sinuses) become inflamed or swollen, a sinus infection and congestion result. Breathing will be difficult, a headache can occur and pain around the eyes and the nose may be present. There are many causes, and sometimes the teeth are to blame.

Significance

• Sinus congestion and infections are most often caused by a cold. Bacteria, allergies and fungal infection are also causes. Also, the sinus cavities can become inflamed by tooth cavities resulting in blocked and congested sinuses.

Considerations

• Some health conditions can cause sinus congestion. A tooth infection or other dental problems are a cause of sinus congestion, and both are often overlooked as the culprit.

Identification

• Many people who suffer from sinus congestion breathe through their mouth making their mouth dry. This can cause bacteria to grow, plaque to form and tarter to build up resulting in tooth decay and worsening existing sinus congestion.

Function

• There are seven sinuses in the head and the one associated with tooth infections and dental conditions is the maxillary sinus. TMJ (improper bite), a tooth fracture, periodontal disease, endodontic (nerve, gum, tissue) problems and bruxium (grinding or clenching of teeth) can all lead to sinus congestion.

Warning

• A reoccurring tooth infection after an extraction can lead to sinus congestion. The sinus cavities may not heal and close, or the trauma from removal can result in sinus congestion.

Expert Insight

• The sinuses sit on the upper jaw, and when they become infected they can cause tooth pain. It works both ways. A tooth infection can cause sinus congestion and pain, and congested sinuses can result in tooth aches.
