Sinus Infections Can Cause Toothaches

Sinus Infections Can Cause Toothaches

Infections of teeth and sinuses are sometimes interconnected. An aching tooth can be caused by an infection in and around that tooth, or from a sinus infection near the tooth, or from both sources.

Sinuses are large air cavities located in your upper jaw above your upper teeth. Membranes that line these cavities can become infected. If the roots of upper teeth near these sinuses are close to such an infection, you may experience a toothache.

To locate the source of pain, a dentist will usually take an x-ray to look for infected roots. If the roots appear normal, he or she will look at how close the sinus cavity is to the base of the roots and seek evidence of an infected sinus.

The tooth also may be tested for sensitivity by tapping lightly on the surface and exposing it to hot and cold temperatures. If a tooth is very sensitive, it’s likely the tooth is the source of the problem. A continual dull ache or throbbing sensation, combined with a lack of response to these tests, may point to a sinus infection.

Treatment for a sinus infection includes antibiotics and decongestants. In some cases, your dentist may refer you to an ear-nose-and-throat specialist. If you are experiencing a toothache, contact your Dentist at Signal Hill Dental Centre as they would be happy to help.
