Tooth Pain from Sinus Pressure: How to Help


Do you suffer from sinus pressure? If so, you’ll know that the pain can sometimes be unbearable. Sinus pressure isn’t just an inconvenience; it can make you lose sleep, cause pain when you’re eating, and overall discomfort. 


As the season changes, more of us are getting infections and colds. However, it’s not just sinus infections that cause sinus pressure, but also seasonal allergies; and they both can cause toothache if the sinus cavities become swollen. The swelling can cause pressure to push onto the teeth below your nasal passage, causing tooth pain. This usually affects the upper teeth towards the back of your mouth. If your pain is getting super uncomfortable, it is best to speak to your doctor or dentists Porthmadog for extra suggestions. 


What is the difference between a normal toothache and a sinus toothache?


More often than not, a toothache which is not sinus related will only affect one tooth. However, when experiencing a sinus toothache, you’ll feel the pain in a few teeth. This is usually the top molars (back teeth) and is often alongside the following symptoms:

  • Pressure and pain on your eyes are forehead

  • Postnasal drip

  • Discolored mucus

  • Ear pain 

  • A sore throat 

  • Lack of taste or smell 


These symptoms all happen due to the nasal cavity affecting our whole face, head, and neck area. A single toothache is usually caused by decay, sensitivity, or damage on one tooth. 


How do I relieve tooth pain from sinus problems?


When you have tooth pain of any sort, it is best to see your dentist and get it checked. They will see if your diagnosis is correct and it isn’t a dental issue. They might even be able to prescribe you something for the pain. 


However, if you can’t get to the dentist, here is what you can do to help in the meantime:

  • Keep yourself hydrated and drink a lot of water

  • Eat foods with anti-inflammatory properties, as this is the main cause of the pain

  • Get calcium and vitamin C in your diet too

  • Eat food which is rich in Omega-3 fatty acids

  • Breathe in steam - this will open your nasal passage and relieve pressure

  • Rinse out your sinuses with a saline solution to add moisture and clear blockages


If your infection goes away, but you are still experiencing pain, there could be something else going on which is causing the issue. Your dentist can rule out any dental problems, and your doctor can see if anything other medical issues are causing the pain.
