Toothache Caused By Sinuses And How To Treat It

What Are Sinuses?

Sinuses are the cavities filled with air in the skull.  There are a number of sinuses, but the pair of sinuses which are associated with toothaches are located behind the cheekbones in the upper jaw. The tips of the roots of the upper molar teeth are very close to the sinus cavity.  This close proximity is why sinusitis is often mistaken for a toothache. When the sinuses become inflamed, this is called sinusitis.  Fluid also builds up in the sinuses which can increase the pressure in the sinuses and cause pain.

What Are Some Signs Of A Sinus Toothache?

  • Pain in a number of the upper teeth.  A toothache caused by sinusitis if often hard to pinpoint to a specific tooth as a number of teeth can feel sore
  • If you have or recently had a cold, flu, stuffy nose, or a runny nose
  • You suffer from allergies
  • Headache or earache
  • Tender cheeks or a feeling of heaviness in the sinuses
  • Sinus pain worsens when you move your head, such as walking, jumping or nodding your head up and down.

How To Treat A Sinus Toothache?

A sinus toothache will often go away on its own as the sinuses become less inflamed.  However, a persistent sinus infection may require a course of antibiotics to clear it up.  Nasal sprays or other medications may also be recommended to help clear up the infection.  Always seek the advice of a medical professional before taking medication to treat a sinus infection.

Sinus Toothache


A sinus toothache may feel very similar to toothaches you’ve had in the past that weren’t related to the sinuses.  A visit to your dentist for a checkup and x-rays can rule out any problems with the teeth, such as tooth infections or cavities.  A doctor can diagnose sinusitis and treat it with the appropriate medications such as antibiotics and nasal decongestants.
