I just found out that one of the sinus nerves runs right next to the roots for your teeth. Immediately explained why teeth hurt when you have a sinus issue. Last time I had a sinus infection my teeth didn't hurt so much as I thought my nose was broken. It was one of the convenient times having a dentist in the family to get a prescription.
