Can A Toothache Cause Sinus Pain?

Posted on October 14, 2021

We wake up after a sleepless night with a headache and pain across the top of our faces. We feel a little dizzy. When we go to brush our teeth; the upper back teeth are tender to the touch. The brushing itself sounds loud and discomforting. What’s going on? Is this a monumental toothache? Or is it something else?

If the discomfort radiates to more than one tooth or is present on both sides of your mouth the chances are that the primary cause of your toothache is not from the tooth itself. It is from your sinus. Inflammation and infection of the sinus is called sinusitis.

The swelling of the lining of the sinus along with mucus production can place pressure on the tips of the roots on our posterior teeth. These roots are in close proximity to the bottom floor of the sinus. This pressure can cause a lot of pain.

What is a Sinus?

  • A sinus is a large space connected to our nasal cavity
  • There are four sinuses that lie behind the eyes, cheekbones, and forehead
  • They moisten and warm air as we breathe
  • They produce mucus which filters out debris and dust from entering our lungs
  • Molars can be in very close contact to the sinus, at times separated by just a thin tissue called the Schneiderian Membrane

Toothaches Caused by Sinus Problems

Due to the proximity of the roots of the upper posterior molars and the floor of the sinus, infections of the sinus can cause tooth pain. Conversely, an infected tooth can cause an infection in the sinus.

If one tooth is very tender, if that tooth has had a history of decay, large restorations, or trauma, if swelling is present, if the tooth is hyperreactive to heat, then there is a good chance that you need to see us at 209 NYC Dental.

If the pain is spread over several back teeth or present on both sides, if you had an upper respiratory infection recently or suffer from allergies, then there is a good chance that your problem is coming from your sinus. Sinusitis is best treated by your physician.
