question: my sinus is very close to my gum line on the upper right side of my mouth and a couple of my teeth feel like the nerve is running through it, feeling like a terrible toothache. My dentist see that it is my sinus. I wish there was a warning when the pain will occur and if there is any thing to help relieve the pain (though it does last for @ 15 min each time it happens) I feel like pulling my hair (and teeth) out while the pain occurs :
