Can air pressure changes cause sinus headaches? and cause pain in teeth ? having big rain storm last 4 days...having pressure behind eye every night with swelling and noticed teeth below eye are hurting. had a root canal 2yrs ago, thought it might help wi

A : A differential in pressure between the sinuses and the atmosphere most certainly can cause pain and headaches. Allergy sufferers will attest to that. Often, sinus pain will also manefest itself as a toothache on the maxillay (upper) posterior teeth. It is the way your brain is interpreting pain impulses. Can't tell sight unseen if you have any problems with your teeth, but if your teeth check out without a problem, then it is most likely your sinuses.

Yes: Changes in air pressure, flying etc can cause sinus pain that feels like tooth pain. The upper molar tooth roots are very close to the sinus and can falsely be diagnosed as tooth related pain. A good differential diagnosis is important!

Absolutely: If pressure builds up in sinuses, it can cause pain. Many of the upper back teeth, especially, have roots that extend into the sinus area. Imagine taking a water baloon filled with very cold water. Press your fingers into it. They will feel the cold, even though they are not in the water. Similar situation with the tooth roots. Fluid in sinuses can cause tooth pain. Good luck.

Tooth pain: Do all the teeth hurt on that side? If they do - try a small test - take some antihistamine and if it still hurts see you dentist - if it doesn't see your doctor.

Dr Ali agreed

Yes: Barometric low pressure systems can cause headaches. A proper diagnosis should be made, avoiding un- necessary root canals. Decongestants are best in those situations. If sinusitis is diagnosed, antibiotics along w decongestants are usually given.
