How Are Sinus Infections  And Toothaches Connected?

Have you ever experienced a toothache that doesn't seem to have a dental cause? The connection between sinus infections and toothaches might be the answer to your problem. Understanding this link can help you manage your symptoms and seek the right treatment.

The sinuses are air-filled cavities located in your skull, particularly around the nasal and forehead areas. The maxillary sinuses, that are just above your upper teeth, play a crucial role in this connection. When you have a sinus infection, also known as sinusitis, these cavities become inflamed and swollen. This inflammation can create pressure that is felt in the roots of your upper teeth, leading to pain that feels like a toothache.

Sinus infections and toothaches share several symptoms, which can make it challenging to distinguish between the two. Common overlapping symptoms include:


  • Pain or pressure in the upper jaw and teeth

  • Sensitivity when chewing or biting

  • Swelling and tenderness around the cheeks and eyes

  • Nasal congestion and discharge

  • Fever and fatigue in severe cases

Sinus-induced toothaches typically affect multiple teeth in the upper jaw, while dental issues usually cause pain in a specific tooth. If your toothache is accompanied by nasal congestion, a runny nose, or sinus pressure, it is likely related to a sinus infection. Sinus-related tooth pain often intensifies when you tilt your head forward or lie down due to the change in sinus pressure.

Some common treatments for treating sinus include over the counter medications, however these are only to be taken after consulting with a dentist. Nasal irrigation can also help clean nasal passages and reduce sinus inflammation. A cordless water flosser by ORACURA® comes with various tips including a nasal tip which can help you clean nasal passages with ease every single day. It is also the one stop shop for the best electric toothbrush that you can buy. These advanced oral care essentials will not only help in improving your oral health but will also provide you with sinus relief.  Drinking plenty of fluids and getting enough rest can also help in your recovery. 

Understanding the connection between sinus infections and toothaches can help you seek appropriate care and find relief more effectively. By addressing the root cause of your pain, you can get back to feeling your best.
